Mountain Chickadee
Poecile gambeli
Adults of both sexes have a black cap joining a black postocular stripe behind distinctive white eyebrows. Their backs and flanks are gray and they have paler gray underparts; they have a short black bill, and a black bib. The typical adult wingspan is 7.5 in (19 cm), and the overall length is 5–6 in (13–15 cm). The Mountain Chickadee is one of 55 species of chickadees and tits. Voice: Their call is a throaty chick-adee-dee-dee, while their song is a 3- or 4-note descending whistle fee-bee-bay or fee-bee-fee-bee. Their song sounds like it is whistling the word "Cheeseburger". They travel in pairs or small groups, and may join multi-species feeding flocks after breeding season.
