Chestnut-backed Chickadee
Chestnut-backed Chickadee
Poecile rufescens
At a Glance
The most colorful of the chickadees, the Chestnut-backed is common in the Northwest. Inland, it may overlap in range with up to three other close relatives; but in the very humid coastal belt, in wet forests of hemlock and tamarack, this is the only chickadee present. In those surroundings its rich chestnut colors may be hard to see, but it can still be recognized by its husky, fast chick-a-dee calls.

Description
4 1/2 -5" (11-13 cm). Rich chestnut back and sides contrasting with gray wings; sooty brown cap (may look black). (In the form found along the central California coast, the sides are gray, not chestnut.)

Behavior
Eggs
6-7, sometimes 5-9. White, with fine reddish brown dots concentrated at larger end; sometimes unmarked white. Incubation is probably by female, but details not well known. If disturbed, adult on nest flutters wings and makes loud hissing noise.
Young
Probably cared for by both parents. Development of young and age at first flight not well known.
Feeding Behavior
Forages mostly by hopping among twigs and branches and gleaning food from surface, often hanging upside down to reach underside of branches. Often probes in crevices in bark, and sometimes takes food while hovering. Readily comes to bird feeders for seeds or suet. May store food, recovering it later.
Diet
Mostly insects, seeds, berries. Feeds on a wide variety of insects, including caterpillars, moths, beetles, leafhoppers, scale insects, small wasps, and others. Also eats spiders, seeds (especially of conifers), and berries.
Nesting
Nesting behavior is not well known. Members of pair may remain together all year. Nest site is in hole in tree, usually low, 2-20' above ground; can be much higher (reportedly up to 80"). Will nest in the same site more than one year. Uses natural cavity in dead or rotten wood, the chickadees often excavating or enlarging it themselves; also will nest in old woodpecker holes or in nest boxes. Nest has foundation of moss, lichens, feathers, bark fibers, plant down, lined with soft materials such as animal hair.
Climate Vulnerability
Conservation Status
Surveys indicate slight declines in population in recent decades, possibly because of loss of habitat.
