There are seven species of Chickadee found in the United States. They are:
Black-capped Chickadee: These spunky little birds live across the northern United States, from coast to coast, and as far north as Alaska. As their name suggests, they are recognized by the black caps atop their heads. They are, by far, the most abundant Chickadee species in the United States.
Carolina Chickadee: Lives in the southeastern and south-central parts of United States. They are very similar to the Black-capped Chickadee in appearance. The two are easily confused in areas where they overlap, and they even interbreed.
Chestnut-backed Chickadee: If you live in the coastal Pacific Northwest and California you have a chance of seeing this bird. Their brown coloring distinguishes them from the Black-capped Chickadee.
Mountain Chickadee: Lives in the mountainous, western regions of the United States. While they may overlap with the Black-capped Chickadee in some areas, they are easy to tell apart thanks to the white stripe near their crown.
Boreal Chickadee: Common in Canada and Alaska, the Boreal Chickadee rarely makes an appearance in the lower 48. With their gray coloring, they are easy to identify.
Gray-headed Chickadee: While similar in appearance to the Boreal Chickadee, it isn’t likely you will confuse the two. The Gray-headed Chickadee lives in the frozen remotes of Alaska and is rarely seen.
Mexican Chickadee: As their name suggests, these birds live in Mexico, for the most part. Their northern range does extend slightly into the mountains of Arizona and New Mexico.
