Abstract
A hand-held unit automatically identifies an animal sound, such as a bird call, by comparing an incoming sound with a stored database. The incoming sounds are divided into phrases, and each phrase is characterized by a finite set of parameters. These parameters are used to identify the nature of each phrase, and the animal is identified by searching a database for characteristic patterns of phrases. In another embodiment, a number of such units are located across a wide area, all of the units being connected to a central computer. The computer analyzes the information received from the various units, so as to track the migratory patterns of birds or other animals.
