The Black-capped Chickadee is easily recognized by its short plump body, solid black cap and bib, and white cheeks.
Animal foods consist mainly of insects and spiders.
Catepillars are preferred in the breeding season. Chickadees have been observed eating deer or skunk fat and fish. The female builds the nest alone, as well as incubating the eggs exclusively. Pairs have set territories, ranging from 1.5 to 5.3 ha. Most pairs persist together for several years.
