Definitions
- the present invention relates to the breeding of swiftlets of the genus Aerodramus and/or Collocalia in an edible bird's nests production facility for producing large quantities of nests. Provision of shelter, food, water, safety and security at a single point of communal congregation; pandering to satisfy the sensory perceptions, innate and instinctive preferences of swiftlets to attract and persuade them to colonize specially configured man made shelters.
- An improved structural configuration derived from utilizing novel production features comprising extracted essence of newly disclosed features; refining and improving features of previously disclosed appliances by means of new inventive steps; and eliminating non-value added components. Utilizing these features in a concentrated manner and deploying them extensively. Such a specialized production facility configured to breed swiftlets for their nests helps in conserving wild species of endangered swiftlets.
- Present method of obtaining edible bird's nest involves collecting and harvesting nests of wild swiftlets in their natural habitats such as mountain caves and limestone cliffs for consumption causing irreversible disruptions and damages to the dwindling populations of endemic wild swiftlets.
- Poachers have been known to raid established roosts of protected and endangered species of swiftlets in national parks and wildlife preserves at night to steal edible bird's nests.
- Nest poachers indiscriminately destroys un-hatched eggs, killing swiftlets chicks too young to fly to safety, disrupting their reproductive life-cycle, threatening their very survival such that some species of swiftlets in South East Asia are fast approaching extinction.
- Cave Swiftlets are contained within the four genera of Aerodramus (formerly Collocalia ), Hydrochous, Collocalia and Schoutedenapus . They form the collocaliini tribe within the family Apodidae. Geographically the genus Aerodramus comprises around 30 species with a habitat range covering southern Asia, south pacific islands and north eastern Australia located within the tropical and sub-tropical regions. Edible bird's nests are derived from cave swiftlets of the genus Aerodramus and/or Collocalia . In particular four species comprising A. unicolor, A. fuciphagus, A. maximus and A. germani are the most prized. A. unicolor and A. fuciphagus (also known as Collocalia fuciphaga ) produces high grade white nests while A. maximus ( C. maxima ) produces lower grade black nests containing more feathers, particles and other impurities.
- A. unicolor and A. fuciphagus also known as Collocalia fuciphag
- Aerodramus unicolor Aerodramus fuciphagus
- Aerodramus maximus Aerodramus germani
- swiftlets Due to the inherent shortness of their legs swiftlets are not able to stand upright, perch horizontally on level surface, or take off from stationary positions by flapping their wings like other species of birds. They must cling vertically at height by gripping the sheer cliff or cave wall with sharp claws to roost. To take off swiftlets releases their claw grips, drop from the vertical clinging surface at height, free fall, spread their wings to glide before flying away.
- the lowest, minimum height that swiftlets will ever “land” or settle down to rest vertically is one meter above level surface. Anything lower and they will not be able to drop, glide and fly away safely. And if they ever land on level ground in the wild, they are as good as dead.
- birds of the avian species comprising swifts and swiftlets lacks such a universal ability to stand upright, and are incapable of self-propelled movement across level ground or horizontal surfaces. They attach themselves high up on sheer cliffs, vertical walls and ceilings of caves to roost.
- Clinging onto the vertical walls and roosting boards 196 is relatively easier than clinging onto the bottom surface of the horizontal dimension/or the ceiling 194 structure; hanging with their bodies upside down from the ceiling. Dangling with their body weight hanging in the air, suspended from the overhead ceiling 194 which forms the lower level surface of the ceiling-floor 194 - 195 structural framework 192 .
- the claws of their feet gripping, grasping and clinging securely onto appendages and anchoring points 500 affixed directly onto the ceiling/or roof.
- This inventive step of providing anchoring apparatus 500 , 501 , 502 enables swiftlets to nests and roosts directly from/or, on the overhead ceiling 194 ; which forms the bottom level surface of substrate 192 ; even without the provision or use of nesting boards 196 .
- present invention provides a method to breed and domesticate swiftlets in an edible bird's nest farm and production facility comprising of: a wholly man made artificial caves system 100 ; a dedicated swiftlets housing structure 200 , and/or converted natural relief such as caves, valleys, cliffs forming the roosting habitat and artificial eco-system 356 , including vacated man made shelters 11 and 14 ; and associated supporting sub-facilities; methods, systems, specialized techniques, equipment and apparatus.
- swiftlets may also roost directly on the overhead ceiling 194 formed by floor 195 boards 192 ; with their bodies hanging upside down, in a horizontally disposed position parallel to ceiling-floor 194 - 195 boards 192 which acts directly as the roosting substrate.
- This swiftlets nesting and roosting niche had until now been left unused; a wasted resource which is non-productive. Utilization of this unproductive space in present invention ensures 100% utility of an available resource which should not have been wasted. Turning an unproductive resource into productive use is a new structural configuration and inventive step which present invention seek to disclose, promote and improve upon.
- a dedicated facility specially configured with new structural configurations and inventive steps comprising horizontally disposed overhead ceiling/or roof equipped with new gripping and clinging apparatus(es) 500 for roosting swiftlets to anchor their bodies securely using their beaks (bills/or mouth-parts) and the sharp claws of their feet; their bodies hanging upside down from beneath the horizontally disposed overhead roosting substrate.
- beaks bills/or mouth-parts
- the sharp claws of their feet Just like cave bats at rest with their bodies hanging upside down from the cave roof; secured to the roosting substrate by the sharp claws of their feet/legs!
- their bodies are aligned with and parallel to the horizontally disposed substrate comprising the ceilings of roosting shelters or cave roofs.
- Present invention also discloses a method of providing a manipulated breeding environment conducive to the birds, such as the replication and re-creation of a natural cave's micro-habitat environment with a temperature of 26 to 28 degrees C., relative humidity of 75 to 90%, darkness with a low luminous intensity of between 1 to 2 lux and provision of suitably configured artificial nesting substrate located at height for swiftlets to: alight, cling onto with their claws to rest; build nests, mate, lays eggs, incubate, brood their young; enables paragliding take off by pushing their legs against the nesting substrate and at the same time releasing their claw grips to drop from height, open their wings to glide and fly away safely.
- Present invention replicated and recreated a man made artificial swiftlets roosting environment, said features being simulative and emulative of a natural cave 77 (refer FIG. 1O ) macro and micro environment comprising speleothems and/or speleogens.
- Speleothems are secondary mineral deposit formed in a cave comprising: dripstones and flowstones. Drip stones comprise of stalactites, stalagmites, columns; while flow stone comprise of draperies, rim-stone dams, stone waterfall formation.
- An object of the present invention is to provide an improved method and system including facilities, apparatus and techniques for the large scale domestication, breeding and rearing of swiftlets for their nests, commercial production techniques and safe collection of edible bird's nests.

Providing a common flight passage way linking together different levels in the cave like housing structures 100 , 200 , 356 .
- FIG. 8E illustrates a structural configuration in which still-well 510 is connected by means of cave-tunnel like passage-ways 79 a to swiftlets housing structure 200 ; passage-ways 79 a are in turn connected to rectangular shaped vertical chasms 432 located at the side and/or a square shaped vertical chasm 432 at the centre of the structure 200 .
- Vertical chasms 432 similar to still wells 510 are empty spaces devoid of any obstruction, configured into the internal structure, starting vertically from the ground to the top of the building. Chasm 432 may have an open top structure for vertical entry-exit; or covered by solid roof 97 .
- FIG. 8F illustrates another embodiment in which housing structure 200 may be constructed in an encircling manner and/or arrangement in which the macro-habitat structure surrounds a large empty space purposely left alone in the middle. This empty space forms a natural still well 510 which regulates airflow and wind speed; and for swiftlets to enter and exit their habitat. All access-ways 12 may be configured to face this internal still well 510 .
- the enclosed encircling outer wall of structure 200 provides a natural wind break preventing the entry of turbulent and high speed wind.
- a pond built at the centre of the still well 510 may be equipped with a water fountain and sprinkling system/or mist generator. Evaporating water provides saturated air with a humidity of 80%-100% which enters the encircling structure and habitat 200 .
- still-well 510 may also be connected to the external environment by means of a chasm 432 for ease of access by swiftlets; with the external entrance shielded by a wind-breaker comprising wall 512 .
- Wall 512 configured with top and bottom mounted wheels running in groves 405 may be moved by means of mechanized systems into desirable positions and secured; to deflect and prevent strong winds from directly entering chasm 432 .
- Such a structural configuration drastically reduces and/or eliminates external wind turbulence.
- Chasms 432 may also be configured with bends, twists and turns to reduce wind speed.
- structure 200 may be built in segments over time.
- An advantage of such a segmented construction lies in costs and economics. farmers only need to build portions of the structure 200 as and when required.
- Segment (a) may be used for establishing an initial breeding stock of swiftlets while segment (b) is kept empty. When the swiftlets population increases over time; and before segment (a) nears full capacity, segment (c) is built and readied before segment (b) is opened for occupation by swiftlets.
- segments (d) to (h) are built as and when needed until the whole structure 200 completely surrounds the stilling well 510 .
- FIG. 8G illustrates a chimney like still-well 510 integrated into the swiftlets housing structure 200 .
- the chimney like still-well 510 is located at one side of the building protected by wind shields 512 on both sides, and inter-connected with the tubular chasms 432 located in the middle of the structure by means of tunnels/or passage ways 79 a .
- FIG. 8H illustrates a method of utilizing a series of bends, twists and turns configured into the passage way 79 a located in the roof of housing structure 11 , and/or 14 leading from access-way 12 a into the internal micro-habitat 17 a where swiftlets roosts.
- Speakers and tweeters 211 may be installed inside and outside the housing structure to broadcast bird calls making the atmosphere cozy and home-like.
- the above bends, twists and turns oriented horizontally or vertically, may also be used in combination with wind diversion chutes 79 x ; mesh screen 513 and pressure activated louvers 514 .
- Mesh screen 513 may be substituted with fixed louvers 514 .
- Such an arrangement is designed to minimize entry of light; slow down external wind currents entering the habitat 17 a and to regulate air speed.
- the internal habitat 17 a environment should not have any strong/or turbulent air current.
- Micro-habitat 17 a comprises rows of suitably configured roosting/nesting apparatus 196 affixed onto the ceiling structure 194 ; and apparatus 500 which may be directly affixed onto ceiling 194 ; including suitable temperature, humidity and darkness.
- High speed wind entering access way 12 a from the side marked “L” may be dissipated, dispersed and reduced drastically by means of an arrangement of diversion chutes 79 x , perforated screens 513 and wind louvers 514 . Such that the little amount of wind entering habitat 17 a causes minimal turbulence for roosting swiftlets.
- Diversion chute 79 x located opposite access-way 12 a , lies directly in the path of incoming wind; diverts high speed wind by channeling it away from the bends, twists and turns that swiftlets enters; while perforated screen 513 at the entrance keeps swiftlets from entering diversion chute 79 x .
- High speed wind exiting from chute 79 x pushes against self-opening louvers 514 . Without the pushing force from the wind, louvers 514 close back. This prevents wind blowing from the side marked “R” from entering access way 79 a , and thus does not affect swiftlets habitat 17 a .
- Wind vanes 118 mounted on the roof may be configured to provide signals for operating variable louvers 514 ; such that during windy conditions, the energy of high winds turning the wind vanes 118 may be converted into an electrical signal used to activate an electrical switch supplying power to adjust the angular variation of louvers 514 .

- FIG. 8I illustrates a structure 200 with a still well 510 in the middle incorporating a spherically shaped flight chamber 259 a and/or, a square shaped flight chamber 259 b for exiting swiftlets to circle around to orientate themselves.
- Swiftlets may circle to build up flight speed as they ascended, before finally shooting upwards vertically to exit the top of access way 12 a .
- Swiftlets may also exit from horizontal access-ways 12 b and tunnel passage-ways 79 a located at various heights of the structure.
- Access ways 12 a and 12 b built on the sides of structure 200 provides a horizontal passage-way 79 a linking still well 510 to the external environment. Apart from regulating wind speed, still wells also reduce light from entering the structure; internal habitat darkness with a luminous factor of between 1 to 2 lux is preferred. In the wild, the natural propensity of cave swiftlets (and cave dwelling bats too) to circle around natural cave entrances demonstrates an inherent need for provision of such a facility within the habitat.
- a forced draught fan 515 powered by prime mover 409 may be used to create an upward draft of air current to provide artificial assistance to carry exiting swiftlets through the top access way 12 a .
- the top portion of still well 510 may be constricted to increase the speed of airflow passing through, carrying swiftlets exiting the habitat.
- Perforated screen 513 may be used to keep out birds from the fan 515 .
- Fan 515 may also be mounted vertically at the bottom of chasm 432 facing skyward; together with the injection of fine jets of water droplets which is speedily vaporized by the forced draught. Air saturated with water vapor, being lighter than dry air, rises naturally. When water vaporizes from liquid form into vapor form, its volume increases exponentially by 1760 times.
- Insects may be injected into chamber 259 a for feeding swiftlets by means of pneumatic systems via pipes and carried upwards by the artificial thermals.
- the bottom of structure 200 may be excavated during construction such that the basement portion may be partially buried underground; increasing the roosting and production capacity of the farm.
- FIG. 8K illustrates a variant form of the embodiment of FIG. 8I and FIG. 8J in which an artificial vertical chasm or crevasse-like valley 432 built in the middle of one side of the structure 200 leads to a still well 510 (vertical shaft) located in the centre of structure 200 with flight chambers 259 a .
- Chasm/or crevasse 432 functions like the tunnels of passage-way 79 ; but provides an extremely large empty flight space rising from the ground to the roof top, surrounded on three sides, hemmed in by; and kept within the steep vertical walls of shelter 200 .
- a vertical wall 512 a may be erected some distance away from the huge gaping open access way 12 e to prevent wind from blowing directly into access way 12 e and crevasse 432 .
- the top of crevasse 432 and flight chamber 259 a may be covered; or it may be left open just like the open top still well 510 .
- Access-way 12 e illustrates a large rectangular passage way or opening; spanning from the ground level right up to the top of building 200 with a width of 2-3 meters.
- Air flow patterns may be projected, anticipated, forecast and established in production facilities by means of studies and experiments, including live testing with large industrial fans in combination with 3-D computerized simulation.
- stilling wells 510 and 511 also controls/reduces the amount of light admitted into the internals of structure 100 , 200 , 356 .
- the required amount of light is preferably regulated to a low luminous intensity of between 1 to 2 lux; though total darkness may provide a sense of security preferred by swiftlets in the natural cave environment. All such nesting structures of present application are specially designed solely for swifts and swiftlets to occupy.
- Such a structural configuration is not inhabitable for other terrestrial based humans and animals such as cats, dogs; birds such as chicken, ducks, poultry, fowls, etc. as there is no light and no significant level or horizontal portions to occupy.
- edible nests may be treated with a sulfite solution to remove bacteria and pathogens; in particular, Clostridium spp.
- nests may be treated with other disinfection systems to kill, inactivate, incapacitate and eliminate clostridium bacteria and their spores.
- One such method may comprise the use of an electrochemically produced mixed-oxidant solution for disinfection of hardy pathogens such as Clostridium spp.
- edible nests of swiftlets may be dried in an enclosed apparatus 152 ; or, a confined room using dry air in combination with a vacuuming compressor.
- a vacuuming compressor Such a method creates a partial vacuum in the confined room which in combination with dried air, vaporizes water on the wet nests speedily.

Description
- This application is a continuation of U.S. application Ser. No. 13/218,197, filed Aug. 25, 2011, which is a continuation-in-part of U.S. application Ser. No. 11/949,695, filed Dec. 3, 2007, which claims priority to Singapore Application 200718112-6, filed Nov. 23, 2007 and Singapore Application 200608249-9, filed Dec. 1, 2006.
- The present invention relates to the breeding of swiftlets of the genus Aerodramus and/or Collocalia in an edible bird's nests production facility for producing large quantities of nests. Provision of shelter, food, water, safety and security at a single point of communal congregation; pandering to satisfy the sensory perceptions, innate and instinctive preferences of swiftlets to attract and persuade them to colonize specially configured man made shelters. An improved structural configuration derived from utilizing novel production features comprising extracted essence of newly disclosed features; refining and improving features of previously disclosed appliances by means of new inventive steps; and eliminating non-value added components. Utilizing these features in a concentrated manner and deploying them extensively. Such a specialized production facility configured to breed swiftlets for their nests helps in conserving wild species of endangered swiftlets.
- Present method of obtaining edible bird's nest involves collecting and harvesting nests of wild swiftlets in their natural habitats such as mountain caves and limestone cliffs for consumption causing irreversible disruptions and damages to the dwindling populations of endemic wild swiftlets. Poachers have been known to raid established roosts of protected and endangered species of swiftlets in national parks and wildlife preserves at night to steal edible bird's nests. Nest poachers indiscriminately destroys un-hatched eggs, killing swiftlets chicks too young to fly to safety, disrupting their reproductive life-cycle, threatening their very survival such that some species of swiftlets in South East Asia are fast approaching extinction.
- The birds called Cave Swiftlets or Swiftlets are contained within the four genera of Aerodramus (formerly Collocalia), Hydrochous, Collocalia and Schoutedenapus. They form the collocaliini tribe within the family Apodidae. Geographically the genus Aerodramus comprises around 30 species with a habitat range covering southern Asia, south pacific islands and north eastern Australia located within the tropical and sub-tropical regions. Edible bird's nests are derived from cave swiftlets of the genus Aerodramus and/or Collocalia. In particular four species comprising A. unicolor, A. fuciphagus, A. maximus and A. germani are the most prized. A. unicolor and A. fuciphagus (also known as Collocalia fuciphaga) produces high grade white nests while A. maximus (C. maxima) produces lower grade black nests containing more feathers, particles and other impurities.
- Scientific classification of these avian species being:
- Kingdom: Animalia
- Phyllum: Chordata
- Class: Ayes
- Order: Apodiformes
- Family: Apodidae
- Genus: Aerodramus
- Species: A. unicolor, A. fuciphagus, A. maximus and A. germani
- Binominal name: Aerodramus unicolor, Aerodramus fuciphagus, Aerodramus maximus and Aerodramus germani
- Common name: Indian Swiftlet, Edible-nest Swiftlet, Black-nest Swiftlet and German's Swiftlet
- Due to the inherent shortness of their legs swiftlets are not able to stand upright, perch horizontally on level surface, or take off from stationary positions by flapping their wings like other species of birds. They must cling vertically at height by gripping the sheer cliff or cave wall with sharp claws to roost. To take off swiftlets releases their claw grips, drop from the vertical clinging surface at height, free fall, spread their wings to glide before flying away. The lowest, minimum height that swiftlets will ever “land” or settle down to rest vertically is one meter above level surface. Anything lower and they will not be able to drop, glide and fly away safely. And if they ever land on level ground in the wild, they are as good as dead. Certain death awaits fallen, stranded and grounded swiftlets as they are attacked and devoured by cave creatures such as snakes, cockroaches, crickets, centipedes, crabs, ants, etc. or, other carnivorous creatures. Or, simply die of starvation. Swiftlets only adapt horizontal positions during the nesting season: mating, eggs laying, incubating eggs, brooding and feeding young chicks; all at great heights.
- The majority of bird species on earth such as chicken, ducks, etc. and other farmed poultry stand upright while foraging, feeding, walking, running, makes their nests and breeds on top of horizontal surfaces on level ground, floor of shelters or level surfaces of structures. However, birds of the avian species comprising swifts and swiftlets lacks such a universal ability to stand upright, and are incapable of self-propelled movement across level ground or horizontal surfaces. They attach themselves high up on sheer cliffs, vertical walls and ceilings of caves to roost. Swiftlets clings to the uneven, jagged, pitted, craggy, pock-marked, calloused and roughened surfaces of vertical walls high up, seeking out small ledges, concave faces, crevices, cavities, clefts, hollows, concavities; protrusions and extensions sticking out from the cave walls; indentations, grooves, surface deformations and depressions in the cave walls or cliff walls upon which to anchor their body and their nests firmly and securely. They had adapted themselves well to a life of living in the vertical dimension and the overhead dimension; clinging vertically onto the high walls to rest, sleep and breed. Attaching their nests securely to and bringing up their young, high up on the
vertical cave walls 16 and nestingpanels 69; including from overhead cave ceiling, stalactites,ceiling beams 193 andoverhead nesting panels 196 of the shelter; even building into a concavity, dome shaped chamber in the overhead cave ceiling—at times, clinging and dangling with their bodies hanging upside down. In fact, anywhere, on any calloused vertical or overhead substrate located at height on which they can get a secure beak-hold; a firm foothold/or claw grips. This is an ecological niche, a realm that swifts and swiftlets had evolved to occupy over the eons. Chicken, ducks and farmed poultry live and breed in the horizontal dimension, on the floor/or a large area of flat level surfaces. Like the majority of terrestrial animals on earth, their living space is on top of the horizontal dimension; their body weight resting on the level upper surface of thefloor 195; capable of standing upright and propelling themselves across the relatively flat areas they occupy. Unlike small light-weight swiftlets, they are not capable of and do not live or breed from the vertical walls and overhead ceilings/or roofs. For swiftlets their living space are in (i) the vertical dimension (its body in a vertical position) and; (ii) the bottom surface of the horizontal dimension/or overhead ceiling 194 (its body in upside down, inverted, horizontal position). Clinging onto the vertical walls and roostingboards 196 is relatively easier than clinging onto the bottom surface of the horizontal dimension/or theceiling 194 structure; hanging with their bodies upside down from the ceiling. Dangling with their body weight hanging in the air, suspended from theoverhead ceiling 194 which forms the lower level surface of the ceiling-floor 194-195structural framework 192. The claws of their feet gripping, grasping and clinging securely onto appendages and anchoringpoints 500 affixed directly onto the ceiling/or roof. This inventive step of providinganchoring apparatus overhead ceiling 194; which forms the bottom level surface ofsubstrate 192; even without the provision or use ofnesting boards 196. This is a new structural configuration enabling 100 percent utilization of the roosting niche comprisingoverhead ceilings 194. - To this end present invention provides a method to breed and domesticate swiftlets in an edible bird's nest farm and production facility comprising of: a wholly man made
artificial caves system 100; a dedicatedswiftlets housing structure 200, and/or converted natural relief such as caves, valleys, cliffs forming the roosting habitat andartificial eco-system 356, including vacated man madeshelters overhead ceiling 194 formed byfloor 195boards 192; with their bodies hanging upside down, in a horizontally disposed position parallel to ceiling-floor 194-195boards 192 which acts directly as the roosting substrate. This swiftlets nesting and roosting niche had until now been left unused; a wasted resource which is non-productive. Utilization of this unproductive space in present invention ensures 100% utility of an available resource which should not have been wasted. Turning an unproductive resource into productive use is a new structural configuration and inventive step which present invention seek to disclose, promote and improve upon. A dedicated facility specially configured with new structural configurations and inventive steps comprising horizontally disposed overhead ceiling/or roof equipped with new gripping and clinging apparatus(es) 500 for roosting swiftlets to anchor their bodies securely using their beaks (bills/or mouth-parts) and the sharp claws of their feet; their bodies hanging upside down from beneath the horizontally disposed overhead roosting substrate. Just like cave bats at rest with their bodies hanging upside down from the cave roof; secured to the roosting substrate by the sharp claws of their feet/legs! Except that in the case of swiftlets, due to their inherently short legs, their bodies are aligned with and parallel to the horizontally disposed substrate comprising the ceilings of roosting shelters or cave roofs. A dedicated facility specially configured for the commercial production of edible bird's nest including persuasive inducement of providing shelter, food and water for wild swiftlets. Provision of the five basic necessities of live comprising shelter, food, water, safety and security at one singular gathering point is an extremely convenient and user-friendly feature of present invention which is beneficial to swiftlets conservation. A life of comfort and luxury provided and accorded in exchange for their abandoned nests. Present invention also discloses a method of providing a manipulated breeding environment conducive to the birds, such as the replication and re-creation of a natural cave's micro-habitat environment with a temperature of 26 to 28 degrees C., relative humidity of 75 to 90%, darkness with a low luminous intensity of between 1 to 2 lux and provision of suitably configured artificial nesting substrate located at height for swiftlets to: alight, cling onto with their claws to rest; build nests, mate, lays eggs, incubate, brood their young; enables paragliding take off by pushing their legs against the nesting substrate and at the same time releasing their claw grips to drop from height, open their wings to glide and fly away safely. Present invention replicated and recreated a man made artificial swiftlets roosting environment, said features being simulative and emulative of a natural cave 77 (referFIG. 1O ) macro and micro environment comprising speleothems and/or speleogens. Speleothems are secondary mineral deposit formed in a cave comprising: dripstones and flowstones. Drip stones comprise of stalactites, stalagmites, columns; while flow stone comprise of draperies, rim-stone dams, stone waterfall formation. The functions and utilitarian purposes of draperies in the form ofcave curtains formation 16 is replicated by man-made vertical wall and verticallyinclined wall overhead apparatus cave pillars 398 by thestructural pillars 98 supporting the building;cave stalagmites 397 by ground basedearthen structure 15. Cave domes 396 by artificial dome 370; halfdomed structure 431;cave tunnels 394 byartificial tunnel 372,half tunnel 430;vegetative growth 399 by strings andcords 502. Speleogens are technically distinct from speleothems, as they are created by the removal of bed rock comprising: pillars; scallops; bone yard; box work; composites. - An object of the present invention is to provide an improved method and system including facilities, apparatus and techniques for the large scale domestication, breeding and rearing of swiftlets for their nests, commercial production techniques and safe collection of edible bird's nests. Wherein, by virtue of superior design and structural configuration in the construction and lay out of production facilities; use of mechanized systems, hi-tech. harvesting equipment and safety apparatus; productivity and efficiency may be augmented tremendously to produce large quantities of clean edible nests of high quality, market value and net worth at much lower production costs than the disclosures of parents Singapore Pat. 135977, U.S. Pat. No. 7,661,391; and U.S. patent application Ser. No. 11/949,695. For example, one hundred units of “A” shaped
nesting structures 400 built compactly, densely packed together in one portion ofshelter such shelters 11 built on level ground, thus saving considerable land area, space, construction and environmental costs. Non-useful features and components are eliminated right from the design stage. Such a method of extracting only the essence, the core ingredient(s); the most vital component of a structure for creation of edible nests, is applied to other features wherein; modified W-shaped ceiling-floor structure 420; semi-rounded and curved cave tunnel-roofs 430; semi-spherical domed cave-roofs 431; etc. may be built densely packed together, one unit next to another, one row on top of another; wherein, rows upon rows, layers upon layers of such roosting and nesting substrates are built in close proximity to each other; optimizing, improving efficiency and productivity, saving space and overhead costs of construction, maintenance; maximizing and optimizing land use; an ecologically friendly design which enhances environmental conservation. However, new structural configurations of the facilities such as “A-shaped”roofs 400, semi-tunnels 430,semi-domes 431,inclined walls floor structure 420, etc. and inventive steps requires new methods, systems, equipment and apparatus for accessing and harvesting nests created at height by swiftlets. Specially configured apparatus such as mobile elevated working platforms comprising: motorized “A”-shapedladder 410,climbing pole 425, “V”-shapedsuspension apparatus 425 v, “Y”-shapedharvesting apparatus 425 y; zip-lines 90; “troglodyte” man-lifts ladder bridge inclined ladders pulley stairs 474,cart 475; vertically disposedharvesting beam 480 andchair 490;inclined harvesting beam 480 a and chair 490 a; etc. as disclosed herein, includingvehicles 444, 444 a; anchoringapparatus 450,harvesting pole 460; are required to work on these novel structures. - Achievement of the desired micro-habitat environ/or parameters comprising: a temperature of 26 to 28 deg. C., relative humidity of 75 to 90%, darkness with a low luminous intensity of between 1 to 2 lux; and provision of suitably configured artificial nesting substrate located at height for swiftlets to alight, cling onto with their claws to rest; build nests, mate, lays eggs, incubate, brood their young; enables paragliding take off by pushing the substrate with their legs, releasing their claw grips, dropping from height, opening their wings to glide and fly away safely. All these may be enabled by means of: extracting the essence, the most important and vital component of a structure, then concentrate on extensive utilization and deployment of these unique property(ies); inventive steps, novel structural arrangements, configuration, fundamental concepts and innovative engineering designs as illustrated in
FIG. 3A toFIG. 3L . New conceptual designs should be used to address and to achieve the ultimate objective of providing a swiftlets shelter with a compatible micro-habitat environment. Not the use of additional auxiliary equipment to achieve removal of micro-habitat limitations created by short comings in design configuration, even though such additional equipment may be used to complement design strategy and to overcome limitations and shortcomings in structural configurations, as they impose additional overhead, recurring operating costs and maintenance costs. As increased production costs reduce cost-efficiency ratio and profitability of farm 113 and 23.

All embodiments disclosed herein works towards provisioning, providing for and making available; fulfilling, gratifying, humoring, satisfying, pleasing, bowing to and catering for the needs of swiftlets; providing the 5 basic necessities of suitable shelter, food, water, safety and security at a single locality for the colony of swiftlets. Such that residential swiftlets are pampered, their every needs, whims and fancy satisfied, gratified and exceeded. A life of comfort and luxury provided and accorded in exchange for their abandoned nests. A swiftlets “paradise” in contrast with the vagaries of natural wilderness! Swiftlets will not move in to occupy shelters that are not conducive and compatible to their requirements, expectations and needs. They have been known to abandon established roosts en-mass if habitat conditions changes, (predators, external disturbances, etc.) by migrating to new shelters. To take off swiftlets pushes their short legs against the roosting substrate and at the same time, releases their claw grips; drop from the vertical clinging surface at height, free fall, spread their wings to glide before flying away—a paragliding maneuver peculiar to swiftlets. Such suitable roosting substrates for paragliding take-offs are provided by embodiments of present invention.

FIG. 1A illustrates the detailed view of the roofing structure 11 (referFIG. 2U ) wherein, a row of “A” shapednesting structures 400 based on and comprising the extracted shape and design of the sharpridged roofs 11 andattics 401 located high up, on top ofartificial shelters 11; in which empty attic-space 401 (lying in between theoverhead ceiling 402 and roofing structure 11) forms amicro-habitat area 17 a in which swiftlets resides in said man-made enclosure 11 (FIG. 2U ). The overhead ceiling 402 (denoted by dotted lines) is omitted from the design configuration as it is not useful in present embodiment. Such a sharpridged roofing design 11 is commonly adapted in the equatorial climate of South East Asia, which experiences heavy rainfall throughout the year. Such a man-made enclosure as disclosed in U.S. Pat. No. 7,661,391 by the applicant and as illustrated inFIG. 2U ; inparticular roofing structure 11; may be used in an extracted and concentrated manner in present embodiment. Since only the top upper portion of the roofing structure comprising theroof 11 and empty space of theattics 401 directly beneath the roof is useful for providing swiftlets with a roosting substrate for clinging, nesting and paragliding take off; a plurality of suchuseful structures 11 may be constructed in close proximity to each other. The bottom, lower portion of the housing structure comprising theceiling 402, walls and floor of theshelter 11, which may not be useful for producing edible nests, may be excluded from the present design configuration. This lower housing structure is substituted by the confined habitat and enclosure 17 provided by the main swiftlets macro-habitat housingstructure comprising shelter natural relief 356 transformed into an eco-farm for breeding swiftlets. Speakers andtweeters 211 may be installed on the structures to broadcast swiftlet's bird calls externally to attract roaming swiftlets to visit the habitat. Tweeters broadcasting swiftlet's chirping sounds may be used internally; together with swiftlets pheromones applied on to the nesting substrate to attract, entice and persuade swiftlets to move in to stay; to make the shelter their roosting habitat. Such recorded bird calls may be broadcast by means of high technology electronics comprising: computerized musical-audio-visual equipment including stereo, hi-fi sound systems, speakers, amplifiers, tweeters; fixed analog and digital musical-audio-visual home entertainment systems; and/or portable mobile musical systems. Such systems may be specifically configured for the sole purpose of attractingswiftlets 61 by means of non-stop repeated playback and broadcast of pre-recorded bird chirps. - The
A-shaped roofing structure 400 forms a structural framework on which may be mounted triangularshaped apparatus Roof structure 11 may also be used as a nesting substrate directly by means of clingingapparatus 407 a; clingingapparatus 500 affixed ontobeam 403. The structure is supported by three lateral/horizontal beams 403; two beams at either sides at the bottom and one beam at the apex; and vertical beams or struts 404. Twoinclined struts 408 may also form an A-shaped support forroofing structure 11.

Otherlike nesting apparatus roofing structure 400 for use. Due to the inclined structural configuration of a nearly vertical drop; nesting structures and apparatus may be built closer together, reducing empty space in between. Thus utilizing valuable space which otherwise would have been wasted. More roosting structures means a higher population density per unit volume of space leading to increased productivity and efficiency. For comparison between theoverhead board 196 affixed to horizontal level comprising ceiling-floor 194-195substrate 192 andbeam 193; and the vertically inclined structures of present embodiment. The empty space in between the roosting substrates may be reduced from between 8-10 feet; to between 4-5 feet. The space saving configuration of the vertically inclined structures doubles the roosting and production capacity of the same macro-habitat comprising infra-structures roof 11 may be configured with a smooth, mirrored orglazed finish 361 to discourage nesting of swiftlets and to enable easy removal of bird feces during cleaning operations. While the inclined downward facingsurface 11 b may be configured with a roughened surface and a variety of gripping surfaces for clinging by the sharp claws of roosting swiftlets comprising: verticaloverhead planks 196; verticallyinclined structure 196 a;multi-tiered roosting structure 196 b; small and short pieces ofextension 360;conical stalactites 375;cylindrical stalactites 376; long pieces of horizontally arranged wide protrudingplank 407; long pieces of horizontally arranged narrowprotruding plank 407 a.

FIG. 1J illustrates a sectional view andFIG. 1K illustrates a perspective view of a method in which the flat, horizontally disposed ceiling-floor 194-195structure 192 may be modified into a wave like pattern forming a “W”-shapedstructural framework 420 for mountingoverhead nesting apparatus 420 a; a wavy undulating structure configured for breeding swiftlets devoid of any significant horizontal/or level surface. The horizontal ceiling-floor 194-195structure 192 is replaced by modified “W” shapedstructure 420. From the diagram and physical appearance, this embodiment may appear similar to the “A” shapednesting apparatus 400 as disclosed above. But in actual fact the “W” shaped infra-structure 420 is based on a conceptual configuration simulative and emulative of the convoluted and heavily folded skin lining the internal surface of our stomach, intestines and the villi; providing an exponential increase in the available surface area in a given volume for absorption of nutrients.Roosting apparatus structural framework 420. Such a structural configuration in which a plurality of levels comprising multiple interlinked units of the W-shapedstructural framework 420 may be built closely packed together inproduction facility roosting apparatus 420 a; and serves to optimize and maximize production of edible nests while saving valuable space.FIG. 1N illustrates a modified triangular shaped (X-section view)apparatus 196 b with the top portion and one side (196 x marked by dotted lines) removed; leaving one stepped-inclined side 420 a.Component 420 a comprises the essence ofapparatus 196 b; which is extracted and used extensively in present embodiment. Several pre-fabricated units ofsuch apparatus 420 a may be mounted on an inclined side of the “W” shapedstructural framework 420.Enlarged structures 420 measuring for example 10 meters in height may be configured with reduced empty space in between the upper and lower levels. Removal of significant horizontal ceiling-flooring 194-195 in betweenstructural framework 420 at the same level (forming a wavy and undulating pattern) provides a multi-fold increase in surface area (similar to the undulating pattern of our stomach) for mountingroosting apparatus 420 a; and additional flight space in the form of “V” shapedvoid 401 b following the “W” contour of the “W”-shaped structure 420 (refer to dotted lines of 192 x, 194 x and 195 x). Such a design configuration creates a large V-shapedempty space 401 b which also serves as a flight space for swiftlets. Thus saving valuable space and construction costs while improving productivity, profitability and the cost effectiveness of the swiftlet's farm! This is an optimization and improvement in the usage of limited space inenclosure 200 which had not been available previously (as disclosed in U.S. pat. application Ser. Nos. 11/949,695; 12/624,995). In fact, the larger in dimension are thestructures 420, the more efficient may be the utilization in a given space. For example: for a large “W”-shapedstructure 420 measuring 10 meters in height, the closer may the distance between the upper and lower levels ofstructure 420 be brought together; such that a vertical gap of 1.5 meter in between the upper and the lowerstructural framework 420 may suffice (compared to the normal height of 3 meters); as the total vertically inclined flight space measures 11.5 meters in height.Apparatus 500 may be affixed onceiling work platforms 410 ofFIG. 1H andFIG. 1I ;troglodyte 440 ofFIG. 4A ,FIG. 4B ;vehicle 444, 444 a ofFIG. 4C toFIG. 4E ; may also be used to access the roosting structures to harvest nests. - In one embodiment, climbing apparatus comprising rappelling equipment such as
ropes 414 may be attached to overhead rail 415 by means of slidingclips 416. Overhead rail 415 may be mounted onhorizontal beam 403 located at the overhead apex of the W-shaped apparatus by means of embedded metal bars 417. Such a method and system of using an overhead mounted sliding apparatus enables a farmer orharvester 378 to move to different parts of the system ofoverhead nesting apparatus 420 to access the edible nests built at height. Equipment, apparatus, systems, methods and techniques for ascending and descending vertical structures such as abseiling and rappelling, traditionally used for sports and leisure in mountaineering, caving, rock climbing, etc; may be employed for occupational tasks and work purposes in the ediblenests production facilities clips 416; or tied ontorope 414. The overheadroller wheel apparatus FIG. 6G may also be used. In another embodiment, a modified variant of embedded metal bar 417 a with a protruding ringed end hanging down frombeam 403 may be configured to provide a “zip line” comprisingcables 90 or rappellingropes 414 strung through the eyes of the ringed end of embedded metal bar 417 a. A multitude of such bars 417 a affixed length-wise alongoverhead beam 403 provides anchoring points for stringing a zip line from one portion of the production facility to another.Harvester 378 may access thezip line 90 orrope 414 at height, hook himself securely to the line by means of detachable sliding carabiner clips, hooks, pulley wheels, safety harness and body suit; in order to harvestnests 62. Slidingboard 490 b may also be used for harvesting.Board 490 b may be ergonomically shaped to fit the contour of the human body to maximize comfort. He may move himself along the length of zip line by pulling the line with his hands, or by gripping and pushing the line with his feet. Triple or quadruple lengths of lanyards may be securely hooked to the zip line; such that at an anchoring point 417 a he may transfer his detachable sliding clips, hooks, pulley wheels and safety harness safely across the fixed rings of bar 417 a to the adjacent joints ofzip line 90. Commonly available over the counter rappelling equipment used for mountaineering may be employed. In another embodiment, aclimbing pole 425 may be affixed securely to overhead mounted rail 415 by means of a mobile slidingclip 416. On thepole 425 may be affixed gripping bars andfoot plates 418 which acts as climbing hand-holds and stepping foot-holds for the farmer orharvester 378 to climb upwards/or downwards. Manual methods of harvesting may also be used in whichfarmer 378 climbs up and down ladders to pluck nests by hand. -
FIG. 1L illustrates a sectional view whileFIG. 1M illustrates the side view of the bottom portion ofpole 425. Thebottom-most foot bar 418 ofhollow pole 425 may be affixed to a specially configuredbar 419 which is in turn affixed to an extendable slidingload bar 421 residing inside ofpole 425. Spring 422 loaded lockingbar 419 which also works as a locking pin, acts as a pinion to keep spring 422 in position.Farmer 378 steps on thebottom-most foot bar 418 to push thelocking pin 419 and extendable slidingload bar 421 vertically downwards. Lockingbar 419 slides down the vertical portion of an L-shapedlocking slot 423; compressing the extended spring 422.Climbing pole 425 is then twisted clockwise by means ofbar 418 to lock thelocking pin 419 into position in the horizontal portion of the L-shapedlocking slot 423. Theclimbing pole 425 withextendable load bar 421 resting onhorizontal beam 403 is now ready for use as illustrated inFIG. 1M . Nearly all the weight offarmer 378 rests on the bottom extendable slidingload bar 421, and on the foot-plate 424.Farmer 378 climbing thepole 425 to harvestedible nests 62 may be safely secured topole 425 by means of ancillary fall arrest equipment cum personal protective equipment such as safety belts, safety harnesses, etc. for working at height. Safety life-line 85 provides another layer of safety. To retract the extended slidingload bar 421, thebar 421 is kept in position by the foot/or weight offarmer 378, while lockingpin 419 is disengaged from the horizontal portion of L-shapedslot 423 by twisting theclimbing pole 425 anti-clockwise usingbar 418. Compressed spring 422 extends, pushingpinion 419 and slidingbar 421 upwards; lifting foot-plate 424 upwards, free from the top surface ofbeam 403.Suspended pole 425 hanging down freely from rail 415 and slidingclip 416; may then be moved, pushed and slid to a new location. The bottom portion ofpole 425 may also be configured withwheels 411 moving inruts 405 built intobeam 403; includingmotor 409 enabling self-propulsion.Poles 425 may be used for accessing roosting structures with shorter heights; whereas, heavy-dutyvertical beam 480 and verticallyinclined beam 480 a may be used for wholly vertical and/or vertically inclined roosting structures rising from the ground level right up to the top-most ceilings and roof tops. - In another embodiment, mechanized “A” shaped staircase-
ladder 410 may be inversely configured to form asuspension climbing apparatus 425 v hanging down from the ceiling beams.Roller clip mechanisms roller wheel apparatus FIG. 6G may also be used to support the weight of the climbing apparatus andharvesters 378. Such a mechanized “V”-shaped stair-case ladder 425 v configured to follow the contour and suit the “W”-shapednesting apparatus 420 may be used to accessedible nests 62 built on the roosting apparatus.Motorized components FIG. 6K may also be used to enable the apparatus to be self-propelled. In an alternative arrangement the bottom part of the “V”-shapedsuspension ladder 425 v may also be supported byharvesting pole 425; thus forming a “Y”-shapedladder 425 y. The bottom ofpole 425 may rest onwheels 411 running inruts 405 configured into thebeam 403. Other features as disclosed inFIG. 6G comprising components FIG. 6K comprising components harvester 378 may climb up and downvertical pole 425 to access the suspended “V”-shaped portion of the “Y”-shapedladder 425 y.Suspended rods 478 may also be flexibly connected to the body of the “V”-shaped ladder to enable rapid dismantling and reassembly of the apparatus in mid-air; in order to bypassvertical beams Harvester 378 may be securely tethered to the rings of anchoring apparatus 417 a while carrying out such maneuvers. Such an apparatus may also be adapted for use withA-shaped roosting structures 400 ofFIG. 1A toFIG. 1C andFIG. 1E . -

A multitude of clinging and gripping apparatus may be installed onwall 69 g comprising: long pieces of widerectangular planks 196 affixed perpendicularly to the wall; short individual pieces ofattachment 360; 360 c with saw-tooth claw grips 204; short and narrow pieces of triangular attachment 360 d; long pieces ofwide boards 407 and long pieces ofnarrow rafters 407 a may be installed lengthwise in a horizontal position relative to wall 69 g.FIG. 2S illustrates aninclined stalagmite 15 a similar in utility purpose to apillar 98 in providing a roosting and nesting substrate.FIG. 2T illustrates anenclosed tunnel 372 a. Flight space comprising empty,void chasm 432 left in betweennesting structures FIG. 2G toFIG. 2L ; to the inclined structures (FIG. 2O toFIG. 2T ) of present application; though the inclined structures may be less productive in terms of quantity per roosting apparatus (e.g. only the bottom side ofwall 69 g is useful); the cleanliness, high quality and high economic value of edible nests produced are guaranteed. However, in comparison with the roostingstructures 196 mounted on horizontal ceiling-floor (194-195) arrangement as illustrated inFIG. 1D , housed in the buildings ofFIG. 2U and/orFIG. 2V ; with the availability of vertical flight space provided by the vertically inclined structural configuration, the distance in between nesting floors (of 8 to 10 feet forconcrete layer 192 cum ceiling-floor 194-195) may be reduced by half to (4 to 5 feet) in between the inclined roosting apparatus (e.g. wall 69 g). Therefore, the number of roosting apparatus may be doubled. Thus, while an inclined structure may be more productive than a horizontal structure; it may not be as productive as a wholly vertical structure due to the latter's dual surfaces production capability. However, should productivity be equated to the quality of the final product produced, the inclined structural configuration won hands down. -

In one form, a man-lift comprising troglodyte 440 a may incorporate self-balancing mechanisms in the form ofmobile counter-weights 437 and/or 438; while troglodyte 440 b may be configured with telescopichydraulic arms 435 mounted at the out-riggers 439 for better balance control; low centre of gravity and a wider base for stability.Counter weight 437 may comprise a miniaturized trolley propelled bycables 90; whilecounter weight 438 may comprise a stack of weigh mounted at the tip oftelescopic arm 412 a. Mobileplatform cum ladders 441 may be mounted inruts 405 enabling them to be moved around easily. Fixed steps/or staircase shapedreceptacles 443 may be affixed and constructed on top ofcurved beams 427. Long pieces of scaffold planks andboards 442 made of light-weight aluminum alloy may be placed onsteps 443; in between twoadjacent beams 427 at the same level or height to form a walk-way enabling harvesters 378 to stand securely while plucking nests built on the overhead roosting structures manually by hand as illustrated inFIG. 4C ;harvester 378 may also useharvesting pole 460 for nests built higher up thestructure 430.Swiftlets 61 may roost directly onceiling tiles 428 which forms the structural framework; by means ofapparatus 500. -
FIG. 4C illustrates a plurality of suitably configured work-carts 444 a propelled by means of aprime mover 444 running onwheels 411 inruts 405 or onlight rails 434 mounted onbeams 403. Such a motorized transportation system may be used to provide the main means of conveyance in the artificial cave system comprisingstructural framework harvesters 378; materials, equipment, products, goods; traveling on top of a multitude of the above said swiftlets roosting structures.Scaffold planks 442 resting onsteps 443 may also be used for harvesting or plucking edible nests by hand. In the confined enclosures and enclosed production systems of present invention, motorized apparatus comprising vehicles 444 a cumprime mover 444; and mobile aerial workplatforms comprising troglodyte 440; etc. running onwheels 411, orlight rail system 434; may be configured with an electrical propulsion system to provide the main mode of conveyance, including motorized staircase-bridges beam habitat environment 17, 17 a, 17 b. Sudden noise in the quietness of the enclosed caves systems may be amplified multi-fold; easily scaring swiftlets into sudden panicky “escape” flights, flights of survival ingrained into the instincts of the birds. Such escape flights might cause the loss of eggs held in between the legs of swiftlets; to be accidentally tossed out of the nests. This problem may be overcome with the use of swiftlets chirps and bird-calls broadcast over a system of speakers and tweeters during harvesting time to mask and avoid sudden noise from scaring the swiftlets into such panicky “escape” flights. But however careful, loud noise may still be caused byhuman harvesters 378,harvesting equipment vehicles 444, 444 a; unintentionally or accidentally in the conduct of work-related activities. All unnecessary audible disturbances should be kept to a minimum in the conduct of all activities inside any of the swiftlets nesting enclosures 17 at all times by all workers. All equipment, methods, systems, apparatus, techniques, etc. shall be configured to minimize generation of noise/or sound. Tools and equipment shall be covered/insulated with a layer of soft, pliable and impact absorbing materials to eliminate and minimize production of noise if dropped accidentally; shoes may be soft-soled; communication systems may be configured with ear phones/ear jacks/micro-phone speakers built into the head-gear/head-set.FIG. 4D illustrates a plan view of aman lift 440; its wheels resting inwheel ruts 405 built intohorizontal beams 403.

FIG. 5A ,FIG. 5B andFIG. 5C illustrates ananchoring apparatus 450.FIG. 5A illustrates the sectional side view of the apparatus whileFIG. 5B illustrates the plan view ofsection 5B-5B.FIG. 5C illustrates the removable handle bar 450 a ofanchoring pole 450. The apparatus comprises of two main components namely: a mobileremovable anchoring pole 450; and fixed anchoring apparatus 450 b installed in a stationary position. Anchoring apparatus 450 b may be securely affixed to the frame work structure ofhorizontal beam 403,main pillars 98,vertical beams 404,curved beams 427 and struts 406 by means of bolts and nuts 447. The hand-held end of theanchoring pole 450 may be slotted into handle bar 450 a withcontrol buttons 448 a and 448 b held in the hands of aharvester 378. While the opposite end which is free moving may be inserted into the recessed slot/orport 449 of fixed anchoring apparatus 450 b. The tip of the free moving end ofapparatus 450 may be configured with alocking pin 451 mounted on amovable pivot 452 for ease of docking with recessedslot 449. Thelocking pin 451 may be configured with an eye 451 a through which sliding pinion 453 passes to securely lock theanchoring pole 450 in place. Thelocking pin 451 may be slotted into the recessedslot 449 of the body 450 b and anchored by means of electro-magnet 454 b. Sliding pinion 453 activated by electro-magnet 454 a and 454 c securely keeps thelocking pin 451 in place by passing through the eye 451 a of thelocking pin 451. - To operate, the apparatus 450 b must first be unlocked. The free end of
mobile pole 450 may be manually brought near to the fixed apparatus 450 b byharvester 378. Pressing arelease button 448 a generates a release signal by a signalgenerator cum transmitter 455 mounted near to lockingpin 451 at the free end ofpole 450. Asignal receiver 455 a mounted on the body of apparatus 450 b receives this signal and acts to energize electro-magnet 454 a to attract movable pinion 453 which moves upwards, thus freeing the locking mechanism. The control mechanism/or signal may comprise remote control radio frequency, IR, UV, for short distance pin-point activation of the docking mechanism. The spade shaped lockingpin 451 mounted at the tip of the free moving end of theanchoring pole 450 is manually inserted into the recessed slot/orport 449 of apparatus 450 b by theharvester 378. Electro-magnet 454 b attracts lockingpin 451 into docking position inslot 449. To lock thepin 451 in position, locking button 448 b is pressed, sending a locking signal totransmitter 455. This locking signal is received bysignal receiver 455 a which acts as required. Electro-magnet 454 a is sequentially de-energized to release sliding pinion 453 which falls through the eye 451 a of lockingpin 451 into the securingslot 453 a. At the same time, electro-magnet 454 c located at the bottom of securingslot 453 a is energized to attract and securely hold sliding pinion 453 into a locked position. The locking mechanism is now activated, securely locking theanchoring pole 450 in position. The hand held end of theanchoring pole 450 is in turn pulled taunt, securely locked and clamped into position at designated anchoring points on the body of thetroglodyte 440. The intrinsic safety design of such an anchoring apparatus is advantageous because in case of power failure, the lockingpin 451 is securely locked in place by the movable pinion 453 which remains in its original position due to gravity. A plurality ofsuch anchoring poles 450 and anchoring apparatus 450 b may be used to lock and totally immobilize thetroglodyte 440, thus making the retractable andextendable arms 435 safe for use. Utility purpose made of a plurality ofsuch poles 450 in addition to thetwin lifting arms 435 gave man-lift 440 the appearance of the long extended appendages of cave spiders, cave centipedes, or cave crabs holding their bodies suspended in mid-air; thus the acronym “troglodyte.” For ease of visual sighting in the dark environment, luminous paint may be used tocoat locking pin 451, recessed slot 453, or apparatus 450 b. - After clearing an area of edible nests, the
arms 435 oftroglodyte 440 may be retracted andharvesters 378 dismounted fromwork cages 436. The anchoringpoles 450 may be unlocked, released and retrieved beforetroglodyte 440 is moved to another location further ahead. To unlock, release and retrieve theanchoring pole 450,release button 448 a is pressed. Electro-magnet 454 b and 454 c are de-energized while 454 a is energized. Movable sliding pinion 453 is pulled upwards by electro-magnet 454 a, thus freeing the lock-pin 451 andanchoring pole 450, which is then manually retrieved byharvester 378. Such a combination of components and mechanisms may be used to keep the lockingpin 451 securely in place. And to keep the mobileaerial work platforms 440 secure forfarmers 378 to work safely at height. - Anchoring
pole 450 may be configured as a complete, single piece for use with fixedcontrol buttons 448 a and 448 b; or with a detachable control handle bar 450 a as illustrated inFIG. 5C . Removable handle bar 450 a may be affixed onto the hand-held end of ananchoring pole 450 for operational use, then detached/or removed frompole 450 to be affixed to anotherpole 450 for use. Anchoringpole 450 may be powered by means of a battery pack carried on a strap/or waist belt worn byharvester 378; or by means of flexible electrical wires connected to the handle bar 450 a. The male coupling of the power cable may be plugged intofemale receiver ports 456 present on the handle 450 a ofanchoring pole 450. The activation switch may comprise ofdual buttons 448 a for “unlocking” and 448 b for “locking” operation; or configured as a single button with dual acting functions for use; such that pressing it once will activate an unlocking function, while pressing it another time will activate the locking function. It may also comprise of a sliding button with unlocking/locking functions. The control and activation mechanism for locking and unlocking ofapparatus 450 may also be directly mounted onanchoring pole 450. Anchoringpole 450 may also be configured with extendable and retractable joints operable by means of hydraulic or pneumatic systems commonly available over the counter. Only after the mobile work platforms had been securely and suitably anchored by means of a plurality ofsuch anchoring devices 450 mayharvesters 378 access the heights to collect nests from the roosting structures and nesting apparatus of present invention. Such anchoring apparatus 450 b and anchoringpoles 450 as disclosed may also be used together with other apparatus of present invention; including stair-case bridges 410; mobileladders cum platform 470; work carts andrail cars 444;work cage 436, etc. securing them into safe operating positions.FIG. 5D illustrates a variant form ofmobile anchoring device 450 used for securing mobile aerial work platforms such astroglodytes 440 andmobile ladders mobile metal plate 457 mounted at the end tip ofpole 450 adheres to a fixed electro-magnetic plate 454 securely affixed to backplate 459. Plate 457 slots easily into thereceptacle 458 and adheres securely to fixedplate 454.Pole 450 is securely locked onto/or attached to suitably designated locations on thetroglodytes 440 andmobile ladders -
FIG. 5E illustrates a high technology ediblenest harvesting apparatus 460 with a customized scrapper blade 460 a at the end: including grappling hooks 461; a swivel antenna 462 carrying a lamp, a micro-camera and a bar-code scanner/or reader; a telescopic swivel antenna carrying awater sprayer 463. Grappling hooks 461 may resemble the mandibles of cave centipedes, cave crickets, etc. The swivel antennas may be configured to be adjustable and tilt-able by means of electronic-pneumatic-hydraulic activation and controls.Harvesting apparatus 460 is essentially an extremely strong, light weight pole configured with nests harvesting paraphernalia at the free end; with a row ofcontrol buttons 448 at the hand held end to manipulate said gadgets. The scrapper blade 460 a may be configured with an adjustable/or tilt-able swivel joint 464; andtelescopic joints 465 on the body ofpole 460 which may be extended and retracted as desired; operable by means of electronic, hydraulic and/or pneumatic systems. Prior to use,harvesting pole 460 may operably be connected to supporting utility systems such as water, electrical, hydraulic or pneumatic systems by means of cables viaports 456 located at the rear of the handle.Pole 460 may be manually brought near to anedible nest 62. The lamp on antenna 462 is switched on and the micro-camera is used to check the nest for the presence of eggs and/or chicks to confirm that it is empty. Live display may be viewed byharvester 378 by means of asmall VDU screen 466 mounted onpole 460. Occupied nests are left alone. The bar code scanner on antenna 462 may be used to scan the identification tag next to the nest to be taken; to prevent over harvesting from a specific breeding pair. Apart from bar-codes, the scanner may be configured to read other forms of identification used for tagging nests, location and specific breeding pairs. Water may be sprayed by means ofsprayer 463 at the nesting substrate and nest attachment base to soften and loosen it, such that the nest may be easily detached from the substrate. The scrapper blade 460 a may be tilted by means of swivel joint 464 into a desirable position; and inserted at the point where the base ofnest 62 is attached to the nest building substrate. Scrapper blade 460 a is then slowly pushed, deeper and deeper in between the nest and the roosting substrate. The grappling hook 461 may be operated to grip thenest 62 before it becomes fully dislodged from the substrate. Thetelescopic joints 465 may then be retracted to retrieve the harvestednest 62. The utility design ofharvesting pole 460 focus on dexterity, maneuverability and practicability of using the apparatus for obtaining nests. Alternatively, a plain harvesting pole with a fixed scrapper blade at the end tip may also be used for harvesting; as practiced traditionally in harvesting cave nests from wild swiftlets in South East Asia. -
FIG. 6A illustrates a mobile aerial work platform in the form of a plain staircase-bridge cum ladder 470, which moves onwheels 411 in theruts 405 ofhorizontal beams 403 mounted on top ofartificial cave structure 430.Harvester 378 may move safely onsteps 410 a on top ofplatform 470 to harvest edible nests from overhead roosting structures andnesting apparatus harvesting poles 460. Such movable work platforms may be moved manually by pushing and pulling; or self-propelled by means of motorizedprime movers 409 mounted on the apparatus; or external motorized primemovers comprising vehicles 444 may be used to provide a means of propulsion on top of the artificial cave structures. Hand rails 467 may be installed for personal safety.Apparatus 500 may be affixed directly ontotiles 428,substrate Swiftlets 61 may roost on roostingapparatus semi-tunnel 430; or attach itself directly onto the structuralframework comprising beams tiles apparatus 500. - The staircase-
bridge 470 may also be immobilized by means of anchoringapparatus 450 at site.FIG. 6B andFIG. 6C illustrates a variant ofFIG. 6A in which mobileaerial work platform 470 a may be mounted on a variable wheel base by means of extendable and retractable jack-uplegs 412 b. Such a staircase-bridge 470 a operated by means of hydraulic systems may be raised up and lowered down when required; by extending/or retracting the jack-uplegs 412 b; and by means of adjusting the spread of the wheel base (narrow/or wide) and height of body from the floor by means of thehydraulic arms 412 a. During movement from one location to another, the platform may be lowered by means ofhydraulic legs 412 b; and the hydraulic legs spread out by means ofhydraulic arms 412 a. This enables the platform to have a lower centre of gravity (wider wheel base), improving stability and operational safety as shown inFIG. 6B . At the desired work location the extendablehydraulic legs 412 b may be raised to the appropriate height; the platform may also be raised by bringing the wheels closer together usinghydraulic arms 412 a as shown inFIG. 6C . The wheels may be locked by means of brakes forworkers 378 to carry out activities on the overhead ceiling such as edible nests harvesting, inspection, repair, etc.Work platform 470 a may also be anchored in position by means of anchoringpoles 450 and apparatus 450 b. -
FIG. 6D illustrates an enlarged diagram of awheel 411 mounted inbody frame 469 withaxle 471 andball bearing 472 resting inrut 405 built into the top surface ofhorizontal beam 403. Such a wheel running inrut 405 may be used withladder Rut 405 may be covered with a layer of tractable material at the bottom to enable effective traction and braking. While a layer of metal sheet or othersuitable materials 473 may be used to cover and reinforce the sides ofrut 405.FIG. 6E illustrates a modifiedvariant wheel 411 ofFIG. 6D such that the modified wheels had an extendedhorizontal leg portion 468 attached toleg 412 b. This may be useful in a constricted area with narrow space between thehorizontal beams 403 and thevertical beams 404. Such a wheel configuration allows a larger space in between the body ofladder 470 c andmain pillars 98 orvertical beams 404, minimizing accidental collision or abrasion of ladder against the vertical beam. Dotted lines show avariant leg 412 c attached towheel 411 which may be used in a hanging form to support the suspended harvesting apparatus ofFIG. 6Q . -
FIG. 6F illustrates various variants of the ladder ofFIG. 6A ; including a shortmobile staircase 474; and awork cart 475 mounted on aninclined beam 408 propelled by a cable-pulley mechanism 160, pulling theharvesting apparatus beam 408 by means ofcable 90. The cable-pulley mechanism 160 may be mounted onmobile apparatus 167, which is securely affixed to rail 168 and moves by means ofball bearings 169. In another arrangement amobile ladder 470 b may be suspended from the bottom ofhorizontal beams 403. Thesuspension ladder 470 b may be attached to overhead C-channel groove 477 by means ofmetal bars 478 affixed tomovable roller wheels 433 andball bearings 472 running in the groove of C-channel 477 as illustrated inFIG. 6G . Such a suspension method may be used to support the ladder while it is being moved but may not be strong enough to fully support the weight of more than oneharvester 378. The weight of more harvesters may be supported by means of extendable and retractable jack uplegs 412 a powered by means of pneumatic or hydraulic systems which at the same time immobilizesladder 470 b during harvesting works.Anchoring apparatus 450 may also be used to secure and immobilizeladder 470 b. Also illustrated is a long harvesting pole orbeam 480 a, vertically inclined at an angulardisposition enabling harvester 378 lying onmobile work board 490 b (substitutes inclined work-chair 490 a), in order to harvest edible nests from beneath the vertically inclinednesting wall roof attics 400; W-shaped ceiling-floor 194-195structural framework 420.

Mobile work-chair 490 is mounted securely ontobeam 480 by means of slidingbrackets 481. A plurality ofrollers 479 mounted in thebrackets 481 provides sliding mobility for work-chair 490 to move up and down thebeam 480. Propulsion may be provided by means ofelectric motor 409 driving a loopedcable 90 mounted inside the hollow cavity ofbeam 480.Work chair 490 mounted on a thick metal back-plate 486 may be attached to securingbrackets 481 as illustrated inFIG. 6I andFIG. 6J .Brackets 481 may be configured to slide easily up and downbeam 480 by means of a plurality ofrollers 479 andball bearing 472 propelled by a loopedcable 90 mounted inside thehollow beam 480.Cable 90 may be powered by means ofelectric motor 409.Brackets 481 may be attached to liftingcable 90 by means ofextension metal piece 487; clamped by means ofclamps 487 a, bolts andnuts 447 onto liftingcable 90. -
FIG. 6K illustrates the front view of the top portion comprising the anchoring cum propulsion mechanism of themechanized harvesting beam 480.Vertical beam 480 may be affixed to a shorthorizontal piece 491. In turn,horizontal piece 491 may be suspended, hanging down frommetal bars 478 affixed to a pair ofmovable roller wheels 433 running in fixed C-channel 477 as illustrated inFIG. 6F andFIG. 6G . Suspension metal bars 478 may incorporate spring 422 to cushion and absorb the lateral movement ofbeam 480. The top portion ofmobile beam 480 may be powered by means ofmotor 409 andgear rail 493 which may be secured to C-channel 477 with holdingbars 493 a.Cables 90 may be wound around the pulley wheel 176. Wheel 176 may be securely affixed tobeam 480 by means ofshaft 471 and nuts 447. Disc brakes 488 affixed topulley shaft 471 incorporates brake pads 488 a mounted in abrake housing 484. Pulley wheel 176,cable 90,shaft 471,nut 447; braking system comprising brake disc 488, brake pads 488 a,brake housing 484; and acable 90 propulsion system may also be used in a similar arrangement at the bottom portion ofvertical beam 480. It may also be used together with thebroad wheel 411 apparatus ofFIG. 6O .Inclined beam 480 a ofFIG. 6F may also be used with such a configuration. -
FIG. 6L illustrates the front view whileFIG. 6M illustrates the sectional side view of the bottom-most portion of an inclinedmechanized harvesting beam 480 a. These two figures illustrate the bottom working mechanisms of theinclined beam 480 a enablingharvester 378 to pluck edible nests built high up on verticallyinclined walls FIG. 6F ,FIG. 6P ,FIG. 6Q ). In thisconfiguration beam 480 a rests on ahorizontal piece 491 with a plurality ofwheels 411 a running on top of a thin skate-blade rail 413. Such an apparatus avoids problems associated with deposits ofbird feces 224 which may require frequent cleaning of wheel ruts 405. Motive force provided by the prime mover, anelectric motor 409 is transmitted by means ofgear wheel 492 to a geartoothed rail 493 running parallel to the length of skate-blade 413. Geartoothed rail 493 is held in position by means of holdingbars 493 a connected along the length of skate-blade 413 at regular intervals.Motor 409 may also provide motive power to drive a winching mechanism 160 (167, 168, 169) as illustrated inFIG. 6F , and in movingcable 90 and work-chair 490 a carryingharvester 378 up and down the length and height of thebeam 480 a.Winching cables 90 bearing the load comprising work-chair 490 a andharvester 378 may be kept insidehollow beam 480 a. -
FIG. 6N illustrates the sectional side view of a variant wheel apparatus for supporting the angular load ofinclined beam 480 a, inclined work chair 490 a, orwork board 490 b,harvester 378 and other equipment as illustrated inFIG. 6L andFIG. 6M . Such an apparatus combines the use of anormal wheel 411 together with a roller-wheel 433. The roller-wheel 433 attached toshaft 468 mounted directly below thebeam 480 a bears the direct load; whileside wheel 411 mounted side-ways, takes the inclined load.Electric motor 409powered gear wheel 492 which in turn drovegear wheel 494.Gear wheel 494 turns ashaft 495 which propelledwheel 411. The apparatus ofFIG. 6L may also be used together with the broad wheel ofFIG. 6O .FIG. 6O illustrates a simplified apparatus configured to provide mobility for a vertically disposedharvesting beam 480 running onenlarged wheels 411 inrut 405. The heavy duty wheel is preferred to take the heavy load of a long and heavyvertical beam 480,work chair 490 andharvester 378. Such a broad wheel also provides increased contact surface area to maximize traction.Long harvesting beam 480 may provide a substitute for thelifting system 82 for accessingvertical walls 69 as disclosed in prior art and parent, U.S. Pat. No. 7,661,391. Alternatively,beam 480 may be substituted by atall monkey ladder 476; or anelongated harvesting pole 420 with the use of safety harness. In another embodiment, winchingcables 90 may be configured withoutbeam 480 andchair 490; but affixed to two anchoring pulley apparatus as illustrated byFIG. 6G andFIG. 6K ; includingpropulsion components FIG. 6L andFIG. 6M at the top and bottom portions of the nest harvesting apparatus. Such a cable pulley apparatus for harvestingedible nests 62 from the inclined roosting structure is illustrated inFIG. 6P .Harvester 378 may be moved up and down roosting substrates by means of thecable 90; securely attached tocable 90 by means of lanyards from his body harness. - Multiple layers of fall arrest protection systems configured into the
harvesting apparatus harvester 378.Seat belt 482 provides fall arrest protection forharvester 378 who may operate the harvesting apparatus from the integrated arm-restcum control apparatus 482 a built intoseat belt 482. A weight activatedemergency braking system 483 linked tomultiple brakes 484 mounted on securingbrackets 481 provides emergency braking whenever necessary. In case the liftingcable 90 breaks and theharvester 378 falls together with work-chair 490, the weight of free-fallingharvester 378 is lifted from the seat; spring loadedemergency breaking system 483 activates, locking and jammingemergency brakes 484.Emergency braking system 483 may employ limit switches, proximity switches, pressure switches or dead man's switches for activation. Such switches are triggered by means of physical contact, or due to the lack of physical contact. Position and weight ofseat belt 482cum control apparatus 482 a provides another activation mechanism; wherein, during a sudden fall, the arm-restcum control apparatus 482 a ofseat belt 482 became lighter and is lifted upward, activating theemergency braking system 483. The fail-safe safety system may be configured such that all units ofemergency brake 484 remains permanently locked in position/armed. Only when thebelt 482 is in a depressed position (due to weight of harvester 378) may theemergency brakes 484 be freed/or disarmed. Manual activation switches or buttons mounted on the work-chair 490 or arm-rest 482 a provides another layer of safety. Alimit switch 485 mounted at the ground level ensures thatharvester 378 is always buckled up; such that only when the harvester fully sits on work-chair/work-seat 490, depressing the spring loadedlimit switch 485 may the fail-safe logic of the PLC control mechanism be disarmed, allowingseat belt 482 to be unbuckled for theharvester 378 to get down. Likewise, only whenharvester 378 buckled up hisseat belt 482 and hooked on tosafety line 85 may the PLC allows power be supplied to theelectric motor 409 to winch the liftingcable 90 carrying work-chair 490 andharvester 490 upwards.Independent safety line 85 providesharvester 378 with the last line of fall arrest protection. Industrial fall arrest systems comprising air bags may be deployed at the bottom of the harvesting beams 480 to provide fall arrest protection in case of an accidental fall. The air bags may be powered by large bottled CO2; triggered by means of radio transmitters activated by means of electronic detectors detecting a high speed descent ofwork chair 490. A plurality of individual air bags attached together vertically may be inflated simultaneously, forming a multi-layered cushion stacked up, one on top of another to break the fall ofwork chair 490 andharvester 378. Such air-bags may be constructed of soft and pliable, yet tough, tear resistant materials comprising thick tarpaulin, Kevlar and other composites; providing adequate safety margin to ensure the safety ofharvesting crew 378. The design configuration of such industrial air-bags may incorporate a plurality of smaller bags (buds) branching off, attached to the sides of the main air-bag; internally segregated by a layer of thinner materials (between main air-bag and the buds) of different pressure ratings designed to rupture easily. Such that after inflation and upon impact, the sudden increase in the pressure of the main air-bag ruptures the layers of thinner materials progressively, releasing the main air-bag's content into the smaller bags attached side-wise, forming a plurality of buds. Such a “budding” configuration of the air-bag helps in absorbing the sudden impact of a fall by deflating partially; and yet, retains adequate inflatable capacity/or buoyancy to provide a soft cushion for landing. -

FIG. 8A illustrates a swiftlets housing cum breeding structure in the form ofproduction facility 200, which is connected to a still-well 510 by means of a plurality of interlinked tunnel like passage-ways 79 a; and the external environment by means of a plurality of access-ways well 510. Physical configuration of a still well 510 may measure 2 to 3 meters, optimally 6 meters in diameter providing a circlingchamber 259 a. Still well 510 comprises an empty void, a vertical shaft orchasm 432 rising from the ground level right up to the top of the chimney-like structure providing a flight space/or aerial passage connecting all levels ofstructure 200. The ceiling-floor 194-195substrate 192; devoid of vertically disposednesting boards 196 orwalls 69; may be directly configured for roosting byswiftlets 61. Clingingapparatus ceiling 194 to provide beak holds and claw holds forswiftlets 61 to cling onto.FIG. 8B illustrates a plan view of the still well 510 structure with a plurality ofaccess ways cum breeding structure 200 while minimizing the entry of external drafts of wind.Structure 200 may form a fully enclosed multi-storied swiftlets-housing structure rising a hundred meters high spread over hectares of land area. Externally such fortress-like-buildings 200 appears pock-marked with rows of neatly arrangedventilation ducts 197 and multiple aerial access-ways 12 of various structural configurations may also be built linking the roostinghabitat 17, 17 a, etc. -
FIG. 8C andFIG. 8D illustrates a modified variant ofFIG. 8A andFIG. 8B comprising miniaturized still-wells FIG. 8C illustrates a miniaturized still-well 511 with horizontally mountedopening 12 a constructed on top of roof-ceiling 11 requiring vertical entry and exit. Swiftlets flew in and out of such access-way 12 and/or passage-way 79 vertically.FIG. 8D illustrates a miniaturized still-well 511 a with vertically mountedopening 12 a and 12 b constructed on top of roof-ceiling 11 requiring horizontal entry and exit. Swiftlets flew in and out of such access-way 12 and/or passage-way 79 horizontally (normally), level to the ground. The access way may be shaped in the form of a square, rectangle, circular, oblong, etc. Such small scale still-wells ways 12 as shown inFIG. 8C andFIG. 8D may be roof mounted/or mounted on the walls of theshelters internal flight passages 79 a; or, it may be directly integrated into the nesting habitat 17. Such small stillwells structure - Aerial entrance to and exit from swiftlets shelters may also comprise of
apertures 12 mounted on the roof top or, high up on the vertical walls for swiftlets to enter and exit. Theaperture 12 may be configured as a square shapedhole 12 a/or, a round man hole 12 b; large enough for a plurality of swiftlets to enter/exit at any one time. Such airborne access-ways 12 which also serves as air intake or exhaust ports for the swiftlets-house ways 12 and caves-tunnels access-ways 79 forswiftlets housing structures openings 12 a; circular, round, elliptical or oval shaped orifices 12 b; rows upon rows of longvertical slits 12 c andhorizontal slits 12 d; built on the walls ofstructure ways 12 a or 12 b may measure: 3 feet by 3 feet wide; or five feet by five feet wide;vertical slits 12 c orhorizontal slits 12 d may measure 12 cm long×5 cm wide; with a multitude of such adequately sized openings for swiftlets to enter and exit. Large scale farms may also be configured withsuch access ways 12, cave-tunnel like passage-ways 79 a; including large scale still-wells 510. - Incorporation of a still-well 510, 511, 511 a into the construction of access-
ways 12 and flight tunnel passage-ways 79 may be used to stabilize air flow patterns and provide better control of the aerodynamics inside the enclosure 17. Such an apparatus in the form of a snout-like tunnel, or chimney may be used to minimize air turbulence in the swiftlets nesting enclosure 17 and micro-habitat 17 a, 17 b. A still-well constructed on top of and around a horizontally mountedopening 12 a on the roof-top may appear like a short snout or chimney sticking out from the roof-top as illustrated inFIG. 8C . While a still-well installed on a vertically mounted opening as illustrated inFIG. 8D may appear like a tunnel. The protruding portion may reside inside of the housing cum roofing structure. A combination of both vertical and level entry and exit may be used in swiftlets housing structures configured with a common specialized still-well 510 built at one corner of thestructure 200. Still well 510 may be connected to all of the plurality of nesting levels in thehousing structure 200. Such a structure reduces and minimizes external air turbulence/high wind currents from entering and affecting the internal micro-habitat 17 a. A slow moving air current or still air is preferred by swiftlets in their nesting habitat. Sudden drafts of fast moving air or gusts of wind at high speed should be avoided at all costs in the micro-habitat 17 a, 17 b. Access-ways 12 and cave-tunnel like passage-ways 79 provides a conduit between the point of entrance/exit and internally built vertical chasms orflight passage ways 432 connecting together the multi-tiered nesting structures stacked one on top of another. Providing a common flight passage way linking together different levels in the cave likehousing structures -
FIG. 8E illustrates a structural configuration in which still-well 510 is connected by means of cave-tunnel like passage-ways 79 a to swiftletshousing structure 200; passage-ways 79 a are in turn connected to rectangular shapedvertical chasms 432 located at the side and/or a square shapedvertical chasm 432 at the centre of thestructure 200.Vertical chasms 432, similar to stillwells 510 are empty spaces devoid of any obstruction, configured into the internal structure, starting vertically from the ground to the top of the building.Chasm 432 may have an open top structure for vertical entry-exit; or covered bysolid roof 97.Vertical chasms 432 provides an internal vertical flight space connecting horizontal flight spaces at all levels of the structure together, such that swiftlets may fly to any part of the internal habitat and enclosure it wishes to.FIG. 8F illustrates another embodiment in whichhousing structure 200 may be constructed in an encircling manner and/or arrangement in which the macro-habitat structure surrounds a large empty space purposely left alone in the middle. This empty space forms a natural still well 510 which regulates airflow and wind speed; and for swiftlets to enter and exit their habitat. All access-ways 12 may be configured to face this internal still well 510. The enclosed encircling outer wall ofstructure 200 provides a natural wind break preventing the entry of turbulent and high speed wind. A pond built at the centre of the still well 510 may be equipped with a water fountain and sprinkling system/or mist generator. Evaporating water provides saturated air with a humidity of 80%-100% which enters the encircling structure andhabitat 200. Alternatively, still-well 510 may also be connected to the external environment by means of achasm 432 for ease of access by swiftlets; with the external entrance shielded by a wind-breaker comprising wall 512.Wall 512 configured with top and bottom mounted wheels running ingroves 405 may be moved by means of mechanized systems into desirable positions and secured; to deflect and prevent strong winds from directly enteringchasm 432. Such a structural configuration drastically reduces and/or eliminates external wind turbulence.Chasms 432 may also be configured with bends, twists and turns to reduce wind speed. In this embodiment,structure 200 may be built in segments over time. An advantage of such a segmented construction lies in costs and economics. Farmers only need to build portions of thestructure 200 as and when required. To start with, only segment (a) and (b) of the macro-habitat structure needs to be built together with the internal wall of still-well 510. Segment (a) may be used for establishing an initial breeding stock of swiftlets while segment (b) is kept empty. When the swiftlets population increases over time; and before segment (a) nears full capacity, segment (c) is built and readied before segment (b) is opened for occupation by swiftlets. Similarly other segments (d) to (h) are built as and when needed until thewhole structure 200 completely surrounds the stilling well 510. -
FIG. 8G illustrates a chimney like still-well 510 integrated into theswiftlets housing structure 200. The chimney like still-well 510 is located at one side of the building protected bywind shields 512 on both sides, and inter-connected with thetubular chasms 432 located in the middle of the structure by means of tunnels/orpassage ways 79 a.FIG. 8H illustrates a method of utilizing a series of bends, twists and turns configured into thepassage way 79 a located in the roof ofhousing structure 11, and/or 14 leading from access-way 12 a into the internal micro-habitat 17 a where swiftlets roosts. Speakers andtweeters 211 may be installed inside and outside the housing structure to broadcast bird calls making the atmosphere cozy and home-like. The above bends, twists and turns oriented horizontally or vertically, may also be used in combination withwind diversion chutes 79 x;mesh screen 513 and pressure activatedlouvers 514.Mesh screen 513 may be substituted with fixedlouvers 514. Such an arrangement is designed to minimize entry of light; slow down external wind currents entering thehabitat 17 a and to regulate air speed. Theinternal habitat 17 a environment should not have any strong/or turbulent air current.Shelter 11 or building 14 serves as the macro-habitat for breeding swiftlets; micro-habitat 17 a comprises rows of suitably configured roosting/nesting apparatus 196 affixed onto theceiling structure 194; andapparatus 500 which may be directly affixed ontoceiling 194; including suitable temperature, humidity and darkness. High speed wind enteringaccess way 12 a from the side marked “L” may be dissipated, dispersed and reduced drastically by means of an arrangement ofdiversion chutes 79 x,perforated screens 513 andwind louvers 514. Such that the little amount ofwind entering habitat 17 a causes minimal turbulence for roosting swiftlets.Diversion chute 79 x located opposite access-way 12 a, lies directly in the path of incoming wind; diverts high speed wind by channeling it away from the bends, twists and turns that swiftlets enters; whileperforated screen 513 at the entrance keeps swiftlets from enteringdiversion chute 79 x. High speed wind exiting fromchute 79 x pushes against self-openinglouvers 514. Without the pushing force from the wind,louvers 514 close back. This prevents wind blowing from the side marked “R” from enteringaccess way 79 a, and thus does not affectswiftlets habitat 17 a.Wind vanes 118 mounted on the roof may be configured to provide signals for operatingvariable louvers 514; such that during windy conditions, the energy of high winds turning thewind vanes 118 may be converted into an electrical signal used to activate an electrical switch supplying power to adjust the angular variation oflouvers 514. -
FIG. 8I illustrates a sectional view whileFIG. 8J illustrates a plan view ofhousing structure 200.FIG. 8I illustrates astructure 200 with a still well 510 in the middle incorporating a spherically shapedflight chamber 259 a and/or, a square shapedflight chamber 259 b for exiting swiftlets to circle around to orientate themselves. Swiftlets may circle to build up flight speed as they ascended, before finally shooting upwards vertically to exit the top ofaccess way 12 a. Swiftlets may also exit from horizontal access-ways 12 b and tunnel passage-ways 79 a located at various heights of the structure. It also provides a large internal flight chamber for incoming swiftlets to slow down their speed, orientate themselves relative to the internal access ways leading to the roosting habitat 17; or, to perform mating dance, socializing, etc.Access ways 12 a and 12 b built on the sides ofstructure 200 provides a horizontal passage-way 79 a linking still well 510 to the external environment. Apart from regulating wind speed, still wells also reduce light from entering the structure; internal habitat darkness with a luminous factor of between 1 to 2 lux is preferred. In the wild, the natural propensity of cave swiftlets (and cave dwelling bats too) to circle around natural cave entrances demonstrates an inherent need for provision of such a facility within the habitat. A forceddraught fan 515 powered byprime mover 409 may be used to create an upward draft of air current to provide artificial assistance to carry exiting swiftlets through thetop access way 12 a. The top portion of still well 510 may be constricted to increase the speed of airflow passing through, carrying swiftlets exiting the habitat.Perforated screen 513 may be used to keep out birds from thefan 515.Fan 515 may also be mounted vertically at the bottom ofchasm 432 facing skyward; together with the injection of fine jets of water droplets which is speedily vaporized by the forced draught. Air saturated with water vapor, being lighter than dry air, rises naturally. When water vaporizes from liquid form into vapor form, its volume increases exponentially by 1760 times. This uptake of a fixed volume of space in still well 510 plus its lighter specific gravity displaces and pushes out air outward and upward, creating a net natural outflow. Specific gravity of air=N2+O2=34 [79%]+16 [21%]=30; while the specific gravity of water H2O=1+1+16=18. This method of providing a forced draft as well as naturally induced draft is equivalent to the creation of an artificial thermal effect, just like a natural current of rising hot air. Such an artificial source of man-made aerial lift created using mechanical means and injected water vapor provides the equivalence of naturally rising thermals used by birds (including gliders bearing humans) to soar high up in the skies effortlessly. Insects may be injected intochamber 259 a for feeding swiftlets by means of pneumatic systems via pipes and carried upwards by the artificial thermals. The bottom ofstructure 200 may be excavated during construction such that the basement portion may be partially buried underground; increasing the roosting and production capacity of the farm. -
FIG. 8K illustrates a variant form of the embodiment ofFIG. 8I andFIG. 8J in which an artificial vertical chasm or crevasse-like valley 432 built in the middle of one side of thestructure 200 leads to a still well 510 (vertical shaft) located in the centre ofstructure 200 withflight chambers 259 a. Such a structural configuration provides an access way for swiftlets entering and exiting theshelter 200. Chasm/orcrevasse 432, functions like the tunnels of passage-way 79; but provides an extremely large empty flight space rising from the ground to the roof top, surrounded on three sides, hemmed in by; and kept within the steep vertical walls ofshelter 200. A vertical wall 512 a may be erected some distance away from the huge gapingopen access way 12 e to prevent wind from blowing directly intoaccess way 12 e andcrevasse 432. The top ofcrevasse 432 andflight chamber 259 a may be covered; or it may be left open just like the open top still well 510. Access-way 12 e illustrates a large rectangular passage way or opening; spanning from the ground level right up to the top of building 200 with a width of 2-3 meters. - In the open skies, swiftlets experiences and are used to the most severe air turbulence such as air current buffeting, thermals, vortices, vortexes, etc. that external atmospheric effects and weather conditions provides. But at rest in the shelters, nesting enclosure 17 and micro-habitat 17 a, 17 b, swiftlets inherently prefers slow moving and non-turbulent air flows. Suitable air flow patterns must be maintained in the nesting enclosures at all times. Extremely fast, and/or excessively turbulent air flows in the nesting enclosure may cause swiftlets to abandon their established roosts, seeking new habitats to colonize. Favorable air flow patterns suitably configured for breeding swiftlets shall be established in production facilities of present invention. Air flow patterns may be projected, anticipated, forecast and established in production facilities by means of studies and experiments, including live testing with large industrial fans in combination with 3-D computerized simulation. Besides regulating air flow within the swiftlets habitat, stilling
wells structure - In another embodiment of present invention, after cleaning, edible nests may be treated with a sulfite solution to remove bacteria and pathogens; in particular, Clostridium spp. Alternatively, nests may be treated with other disinfection systems to kill, inactivate, incapacitate and eliminate clostridium bacteria and their spores. One such method may comprise the use of an electrochemically produced mixed-oxidant solution for disinfection of hardy pathogens such as Clostridium spp. Quote: “The United States does not import raw nests because of the presence of a bacteria, clostridium. All nests destined for the North American market are washed in a sulfite solution and cleaned of impurities before export. (Source: The National Geographic January 1990, Nest Gatherers of Tiger Cave: Page 117)” Unquote.
- After cleaning, treatment and processing, edible nests of swiftlets may be dried in an enclosed apparatus 152; or, a confined room using dry air in combination with a vacuuming compressor. Such a method creates a partial vacuum in the confined room which in combination with dried air, vaporizes water on the wet nests speedily. Introduction of vacuum shifted the equilibrium of relative humidity, partial pressure of water vapor and the vaporization rate of water in the confined space. The cycle may be repeated with the injection of dry air and vacuuming several times in a batch drying process. Alternatively, a continuous process may be used in which continuous removal of air at one end may be combined with controlled injection of dried air into the confined room at the other end. When the required water content (specification) is reached, the process is stopped and processed nests are removed from the room for packaging.

FIG. 8L illustrates the plain view whileFIG. 8M illustrates the side view of the underground configuration of swiftlets shelter 200 in present invention in which safety and security features were incorporated right from the conceptual stage. All swiftlets shelters of present invention may be configured with such enhanced safety and security features to prevent illegal entry by poachers and nests robbers. To discourage nests robbers from tunneling into the shelters, the ground level cement flooring of thestructures concrete base 516; resting on top of large pieces of loose rocks 101. This horizontal base may be surrounded by a vertical reinforcedsubterranean wall 517, which encircles the underground perimeter of the base ofshelter 200. Breaking through thevertical wall 517 andhorizontal base 516 requires the use of heavy duty pneumatic jack hammers and heavy caliber tools. Thewall 517 may in turn be surrounded by anunderground dyke 518 with aplastic bag 519 containingchemicals 520 comprising diluted acids, alkalis and irritating gases. Theplastic bags 519 may be placed in the cavity formed between thevertical wall 517 and a thinretaining dyke wall 518; with the top portion covered by a sealedlid 522.Concrete floor 521 surrounds theshelter 200. The acids and alkalis may comprise hydrochloric acid, sulfuric acid, formic acid, sodium hydroxide, etc; while gases may comprise of sulfur-dioxide, chlorine, ammonia, hydrogen sulfide, etc. at various concentration. The plastic bags used to contain the chemicals are very thin, fragile and easily broken; thus easily releasing its content to repulse any intruders—irritate, itch, burn, choke, suffocate, knock out, incapacitate them to a certain degree. At the same time, released gases are easily detected by smell (human nose) and gas detectors installed in the vicinity which activates security alarms; to warn farm security guards of such underground security breaches. The dyke may also be configured to contain water and/or, linked to a large volume of water stored above ground level. Released fluids may then rush in to inundate the tunnels, flooding them; flushing out the tunneling intruders. If intruders evade and overcome the defenses of thesubterranean wall 517 and continued tunneling upwards from beneath thefloor 516, large pieces of rocks 101 will fall down into the tunnels to crash them. When the rocks dropped, fine strands of trip-wires are broken, activating alarms and sirens. As the reinforced concrete structures offloor 516 andwall 517 requires the use of heavy machineries to break; vibration sensors may be installed and seismic fluctuations monitored by the control centre. The bottom portion ofwall 191 may also be reinforced with heavy duty concrete; while the wall itself may comprise ofdual layers 191 with a thick layer (1 to 3 feet width) of earth 523 in between for insulation. -
FIG. 8N illustrates an insects 525breeding apparatus 530 comprising of an enclosed habitat provided by aplywood box 526 with vertically disposed climbing surface provided by sheets of plastics or old discardednewspapers 527 hanging down from arack 528 located at the upper portion ofapparatus 530.

Insects of appropriate size may be removed from thebreeding apparatus 530 for feeding swiftlets by means of air blown harvesting.Apparatus 530 may be used to breed insects such as cockroaches, crickets, etc. The structural configuration comprising vertically disposed climbingsurfaces 527; and/or vertically inclinedbreeding substrate 527 used inapparatus 530 may also be cross-applied for use in insects breeding apparatus 263, 265, and in containerized transportation apparatus 290 as disclosed in U.S. patent application Ser. Nos. 11/949,695; 12/630,309. - In their natural habitat and the wild environment, humans may be the worst enemies of
edible nest swiftlets 61. In the mutually beneficial symbiotic farmed environment of present invention, mankind may well be the saviour of edible nest swiftlets; their greatest benefactor cum beneficiary. Given private ownership of a resource, man-kind may be turned from destructive exploitation, from being the destroyer, the bane of edible nest swiftlets very survival; into champions of wildlife conservation and protectors of swiftlets! Edible bird's nests are derived from cave swiftlets of the genus Aerodramus; Collocalia; and Apus. In particular the species comprising: A. unicolor, A. fuciphagus, A. maximus, A. germani; C. unicolor, C. fuciphaga, C. maxima, C. germani, C. esculenta, C. linchi; Apus pacificus. - Features of present invention not only provides a conducive environment for full filling and meeting the habitat requirements of swiftlets; but far exceeded any naturally existing conditions for wild breeding swiftlets. The structures and apparatus disclosed herein are specially and specifically configured for this single purpose—to breed swiftlets for their edible nests. All features and individual components, apparatus, techniques, systems and methods as disclosed in present invention may be cross applied, used in combination and integrated with each other for breeding of
edible nest swiftlets 61 to produce edible bird'snests 62 for human consumption; including all related prior art disclosures of the parent applications, child applications, continuation-in-part applications, continuation applications and divisional applications. Finally, it is to be understood that various alterations, modifications and/or additions may be introduced into the constructions and arrangements of parts previously described without departing from the spirit or ambit of the invention.
