´╗┐Backed Chickadee Pictures

Status and Distribution Common. Year round: Coniferous forests, especially of Douglas fir, and mixed and deciduous woodlands. Dispersal: postbreeding movements have been noted to higher elevations in British Columbia and to lower elevations in Oregon. Vagrant: wanders irregularly inland as far as southwestern Alberta and casually south of its usual range to southern California.

The chestnut backed chickadee is curious about humans, and spends the postbreeding and winter seasons foraging noisily in mixed species flocks. Unlike other parids (except for the mountain chickadee), it forages high in the canopies of tall conifers. This species is the smallest chickadee in North America. One of the 3 "brown backed" species (along with boreal and gray headed), its nominate subspecies is the most richly colored parid. Polytypic. Length 4.8" (12 cm).

Geographic Variation Three subspecies. The widely distributed rufescens is the most colorful, with a rich chestnut back, bright white edgings on the greater wing coverts, and extensively bright rufous flanks. The other 2 subspecies are restricted to coastal California; they differ notably on the underparts. In Marin County, the neglectus has reduced, pale chestnut flanks that do not contrast conspicuously with the whitish breast and belly; barlowi, found from San Francisco to northern Santa Barbara County, has grayish flanks, tinged with olive brown.

Voice Call: a hoarse, high pitched, rapid sik zee zee or just zee zee; also a characteristic sharp chek chek. Song: no whistled song is known.

Population Its range has expanded southward and eastward in recent decades from humid coastal regions to the drier eastern San Francisco Bay area and the forested Sierra Nevada in Women Canada Goose Montebello Parka Red Dublin California. Numbers appear to be stable in the northern portion of the range, but recent declines in the interior expansion area have raised conservation concerns.

Similar Species The boreal chickadee also has a dark brown cap and rich brown sides and flanks, but it has predominantly grayish cheeks, lacks a rufous tint on the back and rump, and shows no white wing edgings.
