The Mexican Chickadee (*Poecile sclateri*) is a small, charismatic songbird, measuring approximately 12-13 cm (4.7-5.1 inches) in length with a weight of 10.5-12 grams (0.37-0.42 oz). It is characterized by its distinctive black cap and expansive black bib, sharply contrasting with prominent white cheek patches that extend to the nape.

This species primarily inhabits high-elevation pine-oak and mixed coniferous forests, typically found between 2,000 and 3,500 meters (6,500-11,500 feet) above sea level.
Their diet primarily consists of insects and spiders, including caterpillars, beetles, and insect larvae, supplemented by seeds, especially those from conifers, and occasionally small fruits or berries. They mainly forage by gleaning from vegetation.
Mexican Chickadees are highly active, diurnal birds, spending their nights roosting in tree cavities or dense foliage to conserve warmth. Foraging involves acrobatic gleaning from bark, twigs, and needles, often hanging upside down to access hidden insects and seeds. They are known for caching fo...
