Chickadees are active, acrobatic, curious, social birds that live in flocks, often associating with woodpeckers, nuthatches, warblers, vireos, and other small woodland species. They feed on insects and seeds, but seldom perch within several feet of one another while taking food or eating. Flocks have many calls with specific meanings, and they may contain some of the characteristics of human language. Overall populations increased slightly between 1966 and 2015, according to the North American Breeding Bird Survey. Their western populations slightly declined during this time, but the loss was made up by an increase in eastern populations.
