Adults of 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 typical adult wingspan is 7.25 inches (18.4 cm), and their overall length is 5 inches (12.7 cm).

Mexico's only chickadee is a permanent resident of wooded highlands, and its range extends north into southern Arizona and New Mexico. Although primarily nonmigratory, Mexican Chickadees sometimes fly to lower elevations during the cold of winter.

The Mexican Chickadee, Poecile sclateri, is a small songbird, a passerine bird in the tit family Paridae.

The American Ornithologists' Union has been treating Poecile as distinct genus for some time already.

The nest is constructed by the female and consists of grasses, moss, strips of bark, and is lined with animal fur. 5 - 8 ovate white eggs, marked with fine reddish brown spots, are laid and are incubated for 11 to 14 days by the female. The young fledge in 18 to 21 days.
