The Mountain Chickadee is a small songbird, a passerine bird in the tit family Paridae. Often, it is still placed in the genus Parus with most other tits, but mtDNA cytochrome b sequence data and morphology suggest that separating Poecile more adequately expresses these birds' relationships . The American Ornithologists' Union has been treating Poecile as a distinct genus for some time.
The Bailey's chickadee is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
* Bailey's chickadee is named after Florence Bailey (1863-1948), the first woman to become a member of the American Ornithologist's Union in 1929. She was strongly opposed to the use of bird feathers in women's fashions, and encouraged the use of binoculars rather than guns to be aimed at birds. More
