Chestnut-backed Chickadee

The Chestnut-backed Chickadee, Parus pubescens, is found in the
Pacific Northwest of the United States, as well as western Canada and southern Alaska through central California. It is a permanent resident within its range.

Its habitat is low elevation coniferous and mixed coniferous/deciduous forests. It is a cavity-nester, usually utilizing an abandoned woodpecker hole, but sometimes excavating on its own. It lays 5-9 eggs per clutch.

Its food is largely insects and other invertebrates. Chestnut-backed
Chickadees take some seeds, especially those of conifers, and fruit.
