Chestnut-backed Chickadee

Chestnut-backed Chickadees are found along the west coasts of North America, from Alaska to southern California. Evolutionary studies suggest, although their crowns are black, they are closely related to Boreal Chickadees (Dahlsten et al. 2002). Although seeds and other plant materials are consumed, these chickadees specialize on insects and arthropods. They are particularly fond of insects on Douglas Firs. This photo was taken in Lacey, Washington.
