Abstract
ABSTRACT OF THE DISCLOSURE
A portable, compact, hand held, all weather apparatus for identifying of birds through audio recognition by the use of a built-in audio receiver and prerecorded and blank memory chips. A microprocessor is programmed to conduct a sonagraphic comparison of bird calls as recorded with sonagrams of a plurality of birds stored in memory. A built-in visual screen displays data from the memories library in both a text and graphic format upon a successful sonagraphic identification of the bird being made. It is also possible to use the apparatus as a recorder in order to digitally record and store in memory individual bird songs and information of the owner's choice.
A synthesized version of the bird's song can be produced for audio comparison. An internal power source supplies power to the components.

Description
~ 2089597 ` The present invention relates to an apparatus for identification o~ a bird through audio recognition.
., ¦ 5 BACKGROUND OF THE INVENTION
Persons engaged in bird watching, during the course of their observations, hear the calls of birds hidden by i vegetation. Amateur bird watchers have books to assist them ¦ in making visual identification, but no aids for audio 10 identification.
SUMMARY OF ~HE INVENTION
j~ What is required is a compact, portable and user friendly ;~ apparatus for field use by amateur bird watcher~ to aid in the 15 identification of a bird type through audio recognition.
~j According to the present invention there is provided an apparatus for the identification o~ a bird through audio comparison and recognition by the use of a built-in audio ~', 20 receiver and prerecorded and blank memory chips. The audio 3 receiver is connected to a microprocessor such that a call of a bird received is digitally recorded. A microprocessor is programmed to conduct an audiographic search and comparison of the sonagram of the bird call from preprogrammed or owner 25 imputed reference libraries containing data on a plurality of birds stored in their memories. The memory libraries will be in the form of separate purchase prerecorded chips containing either a selection of birds most common to a particular region or some other combination of birds or family of birds and in ~ 30 the form of separate purchase blank memory chips for the `I inputting of owner generated data. Both types will be purchased individually and installed on the modem board by the owner. Memory storage capacity can then be increased to meet the demand. A visual display sareen is provided whereby data 35 from the libraries is displayed in both a text and a graphic ~' format upon a successful sonagraphic identification of the bird being made. An internal power source supplies power to the components.

;l Z ` 2089~97 ~ ! 2 .. j, ; The apparatus as described enables an audio recognition of a bird to be made through a comparison of sonagr,~ms.
Although beneficial results are obtained through the use of the apparatus as described, bird watchers generally prefer some 5 ~Zorm of cross-checking be built into the identification to en~,ure that an error is not made. Bven more beneficial results may be obtained by having an audio synthesizer connected to the 7i microprocessor whereby an audio reproduction can be made of any -~i bird call stored in memory. This feature enables the bird ~`¦ 10 watcher to verify the result in two ways. Firstly, the ~' birdwatcher can produce a synthesized version of the sonagram for the bird call in order to verify what was digitally j recorded. Secondly, the birdwatcher can play a synthesized ~l version of the sonagram comparator call as stored in memory for ;~l 15 the bird species identified to verify that the comparator call from memory matches what he or she is hearing from the unidentified bird hidden by vegetation. An ear phone is provided for whenever muted listening is preferred.
~k~ ` .: .
~3; 20 Although beneficial results are obtained through the use ~, of the apparatus, as described, bird watchers generally like to keep a record of their bird s3ightings. Such records generally include such data as date, time, weather, location, together with a bird count. Even more beneficial results may, ~i~

Microprocessor 14 i8 connected to audio receiver 12 such that a call of a bird received is digitally reaorded as a sonagram. To facilitate the description of operation which follows the memories of microprocessor 14 will be described in termæ of accessible memory 13, read only or closed memory 16 and database 18. An example of a sonagram i8 illustrated in FIGURE 3. Microprocessor 14 is programmed to conduct a comparison of the æonagram of the bird call with sonagram call comparators for a plurality of species of birds stored in memorieæ 13 and 16. Microprocessor 14 also ha~ inccrporated within it a database 18, adapted for recording data with ~:~
respect to bird sightings. A visual display 20 i~ provided whereby data stored in memorieæ 13 and 16 relevant to a ~elected specieæ of bird is displayed upon a æonagrahic identification of the bird call being made. A keyboard 17 is connected to microprocessor 14 to enable data regarding bird sightingi to be input to the database. An audio synthesizer 22 is connected to microproceæsor 14 whereby an audio reproduction can be made of any bird call stored in memoryr 3S An ear phone adaptor 24 iæ connected to audio æyntheæizer 22 whereby ear phones (not shown) may be connected to audio syntheæizer 22 for the purpoæe of monitoring the audio '' '~
.. ~, :~' 2089~7 reproduction of a selected bird call. In the illustrated embodiment an internal speaker 25 is provided, which gives the ~i birdwatcher the option of listening with or without wParing ear j phones.
