Barlow's chickadee

The Chestnut-backed Chickadee is a small passerine bird in the tit family, Paridae.

The Barlow'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.

One would hardly expect Barlow's chickadee to differ materially in its habits from the other two races of the species, and this seems to be the case, though differences in environment may cause it to select unorthodox nesting sites, as the following quotations will show.
