Chickadees are small, nonmigratory birds belonging to the family Paridae. They are easily recognized by their distinctive black caps and white cheeks. Common species include the Black-capped Chickadee and the Carolina Chickadee. These birds are known for their cheerful, whistled calls, which sound like "chick-a-dee-dee-dee," and they often visit backyard feeders. Chickadees primarily eat insects, seeds, and berries. They are social birds, often found in small flocks, and are known for their curious nature. During winter, they can be seen foraging for food and hiding it in tree crevices to eat later.
