The two most numerous chickadee species in North America are the black-capped chickadee found primarily throughout the northern U.S. and Canada, and the Carolina chickadee native to the southeast U.S. Both birds have a distinctive black cap and bib separated by white cheeks, and gray back and wings. Their bodies have an orange cast, but brighter on the black-cap and with more gray on the Carolina. Chickadees eat mainly insects during warm weather, supplementing their diet with seeds and berries in winter. The two species, which are so similar that they occasionally interbreed where their ranges overlap, don’t migrate. This house (from “Easy to Build Birdhouses“) is designed to meet the chickadee’s particular needs.
