The Carolina Chickadee is a small songbird, related to other species of chickadee and tit. The species is very similar to the Black-capped Chickadee, which generally lives further north. Where the ranges overlap, they are very difficult to tell apart.
Carolina Chickadees are cavity nesters, which means they will use nest boxes if they are provided. They are year-round residents and will form large flocks in the winter with other small birds like titmice and nuthatches.
