Mexican chickadee

The Mexican chickadee (Poecile sclateri) is a small songbird, a passerine bird in the tit family Paridae. It is still often placed in the genus Parus with most other tits, but mtDNA cytochrome b sequence data and morphology suggest that separating Poecile more adequately expresses these birds' relationships (Gill et al., 2005). The American Ornithologists' Union had been treating Poecile as distinct genus for some time already.

Adults are 12.5–13.5 cm long with a wingspan of 18–21 cm and a weight of 7.5–11 g. Both sexes have a black cap, white cheeks, and a short black bill. Their backs and flanks are gray and they have paler grayish underparts. Similar in appearance to the black-capped chickadee and mountain chickadee, the Mexican chickadee can be distinguished by its longer black bib, which extends from its chin down onto its upper breast. A whitish band below the bib extends down the center of the belly.

The Mexican chickadee's song is distinct from other chickadees; it is a complex burry trilled whistle of chischu-wur and a rich cheelee. They travel in pairs or small groups, and may join multi-species feeding flocks.

The nest is constructed by the female in a snag or tree cavity up to 18 m above the ground, and consists of grasses, moss, strips of bark, and is lined with animal fur. She lays between five and eight ovate white eggs, marked with fine reddish brown spots. Their breeding biology is not well known, but it is estimated that eggs are incubated for 11–14 days by the female, and the altricial young fledge in 18–21 days.
