Guide to Boreal Birds
Perching Birds Overview
These birds are constantly active -- hopping, often feeding upside down, clinging to the underside of twigs and branches in their search for insect eggs and larvae. Flocks of this tame and inquisitive bird spend the winter making the rounds of feeders in a neighborhood, often appearing at each feeder with striking regularity. Chickadees form the nucleus of mixed flocks of woodpeckers, nuthatches, creepers, and kinglets that move through the winter woods. In spring, chickadees disband into the woods to nest. Black-capped Chickadees usually prepare their own nesting hole in soft, rotting tree stumps. Enticing them into breeding boxes is difficult unless the boxes are filled with sawdust, which deceives the chickadees; they carry the sawdust out bit by bit and accept the box for nesting. The Black-capped Chickadee is also the official bird of New Brunswick and the state bird of Maine and Massachusetts.
