Here you can identify the sounds and bird song of the black-capped chickadee. Listen first for the two-note whistle of the male Black-capped Chickadee. It’s a very clear two-note song that drops in pitch and sounds like “fee-bee.” Now you know that THAT sound is! The males begin singing in mid-January, and the song increases in frequency as winter progresses. Females also sing occasionally. Then, listen for the chickadee call which sounds like “chickadee-dee-dee” using increasing numbers of dee notes when they are alarmed.
