For the Machine: The Identiflyer Lyric solves the problem of learning bird song with Learning Lyrics, words and phrases that help connect the music to the bird. For example, "Drink your tea" sounds just like the Eastern Towhees song. The songs are so rich and crystal clear that birds will even recognize their songs. It's fun to call in birds so you can take better pictures but be sure to use ABA guidelines for using bird song recordings. In Lyric Mode you hear the birds name, see its picture, hear a verbal description of the song (lyrics) and then hear its song. You can learn 10 unique bird songs in 10 minutes!
