Description
Technical Field
The utility model relates to a protection beaver, especially a bionical cave of protection beaver.
Background
The beaver (known as Castor fiber) is the largest middle-sized amphibious animal in Rodentia, and belongs to the family of beaver and the genus of beaver. The beaver is fat and strong in body shape, has no obvious difference between female and male, and has short and blunt head, small eyes, small ears and short neck. The incisors are sharp, the masseter is developed, and a 40cm tree can be cut off in 2 hours. The forelimb is short and wide, without foreweb, the hindlimb is strong and powerful, the toe has full web, the tail is big and flat. The weight is 17-30 kg, the body length is 60-100 cm, and the tail length is 21-38 cm; the baby beaver just born is about 30-40 cm long and about 700g in weight.
A beaver moves at night, rarely goes out of a hole in the daytime, swims and dives well, does not sleep in winter, has weak self-defense capability, is small in gallbladder, likes a quiet environment, jumps into water when frightened and dangerous, and vigorously beats the water surface by using the tail to warn the same kind. The beaver likes to eat the tender branches, barks and roots of various plants, but also eats the aquatic plants, the tender branches, leaves and barks of the poplar and the willow. In summer, the beaver also eats herbaceous plants such as rhizoma Acori Calami, rhizoma Sparganii, herba Alii Fistulosi and Gramineae; in autumn, the beaver moves frequently in the morning and evening, cuts off branches into about 1 meter, and stores in deep water near the opening for later eating. The nutria inhabit the forest coastline in the cold and warm zone and the subarctic zone, inhabit on the shore, and select broadleaf dense forest, shrubbery and riverside valley with smooth and deep water flow as inhabit sites. The female nutria is bred for 1 time every year, mated for 1-2 months, farrowing for 4-5 months, 1-6 young baby per fetus, the gestation period is about 106 days, the lactation period is about 2 months, the young baby swims 2 days after birth, and sexual maturity is 3 years. The service life is 12-20 years. The natural enemies of the beaver are mainly wolfs, dogs, bears and foxes; in addition, the cattle usually step down the nest of the beaver in winter, so that the beaver is dead without home in winter; in order to obtain precious beaver fur and precious spice-beaver fragrance, people sometimes make hunting.
One unique feature of the beaver is that the beaver is a dam, and all the places where the beaver inhabits or inhabits are ponds, lakes or marshes. The beaver generally builds a nest near water, a nest room is built by branches and soil, and the height of the ground is 0.8-1.9 m. The dwelling mode of the beaver mainly comprises 3 types of hole dwelling, nest dwelling and hole nest dwelling combination. Holes are both permanent and temporary. In spring flood period every year, because ice and snow melt and river water flood, part of the beaver holes are submerged by flood, so that the beaver is forced to move in short distance, and simple holes are built on the branch channels or the small islands for temporary or refuge. The permanent cave is a place for the river raccoon to live through winter and breed, and the structure is relatively complex. The holes are generally distributed in a higher (more than 1.5m from the ice surface) section of the river bank; the hole-nest combination (i.e. underground with a hole system, and a nest with a civil structure added on the ground) is mostly distributed on a medium river bank with the height of below 1.5m from the ice surface. The simple nest is built in the marsh or on the island of the shallow water land. Many of the cave systems and the cave nests are in river bend sections with gentle water flow, the water depth is generally more than 2m, and the river width is about 15 m. Castors usually build 2-8 temporary caves near the nest for emergency refuge and temporary rest.
