Would-be birders are often stymied in their attempts to identify a particular species. As in, you can hear the bird but not see it, and even if you can remember the bird’s call when you get home, it’s a not easy to find a match among the dozens of calls on a bird call CD. Mark Berres, CALS assistant professor of animal sciences, developed an alternative: a smartphone app called the Wisconsin Bird Identification Database, which allows users to record bird songs and identify them remotely. The app transmits a portion of the recorded call to a remote server, where it will be compared to a bird call database. If there’s a match, the server will send back info on the bird along with an image.
