@soph_sol okay but chickadees literally just say their name like pokemon, *surely* everyone can do that one
@Satsuma no that's the chickadee call! the song (at least for black-capped chickadee) is a two-note clear-toned whistle
@soph_sol that makes sense! what cool little birds
@Satsuma they really are! chickadees are a gift to us all ♥️ 
@Satsuma haha yes it does feel counterintuitive! but the complexity in chickadee calls is about communicating info on potential dangers! the most obvious being, the more dees at the end (chicke-dee-dee-dee-dee-dee-dee-dee-dee-dee...), the more worried other birds should be. and many other species of songbird pay attention to the warnings in chickadee calls, not just other chickadees!
