The BirdSong IdentiFlyer from For the Birds adds a new dimension to your interest in birds because it makes it easier to identify birds by learning their songs. Most experts use the bird’s song as the primary way to identify the bird but it was hard for novice birders to learn bird songs because CDs and recordings were difficult to use. The portable IdentiFlyer solves that problem. Take it outside, insert a habitat SongCard (like YardBirds One) and press a few buttons until the song on the card matches the bird that is singing.
