Mountain chickadee
species of bird

The mountain chickadee (Poecile gambeli) is a small songbird, a passerine bird in the tit family Paridae.
Taxonomy
The specific name honors naturalist William Gambel. The mountain chickadee was formerly 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. Molecular phylogenetic studies have shown that the mountain chickadee is sister to the black-capped chickadee (Poecile atricapillus).
Description
Adults of both sexes have a black cap joining a black postocular stripe behind distinctive white eyebrows. Their backs and flanks are gray and they have paler gray underparts; they have a short black bill, and a black bib. The typical adult wingspan is 7.5 in (19 cm), and the overall length is 5–6 in (13–15 cm). The Mountain Chickadee is one of 55 species of chickadees and tits. The mountain chickadee can be distinguished from other North American chickadees because mountain chickadees are marked with a white line through the side of their black cap, whereas all other North American chickadees have a solid black-cap. Another difference between the mountain chickadee and the 55 other species of chickadees is their location, range, and habitat.

Why this record matters
“Mountain chickadee” is worth following because a concise public description often conceals a longer documentary argument. Here, Mountain, chickadee and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 18, 2026. The linked authority identifier is Q973320. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
