Leucistic Black-Capped Chickadee

Jen Goellnitz

In some cases, partial leucism can lead to misidentification of the bird if the leucism is not recognized. This black-capped chickadee (Poecile atricapillus) has leucistic feathers on its crown, giving it a striped appearance that could be confused with a mountain chickadee (Poecile gambeli). The extent of the white, however, including how it protrudes into the black chin, identifies the bird as leucistic, and the extensive white on the wings is characteristic of black-capped chickadees rather than mountain chickadees.
