The Boreal Chickadee ("Poecile hudsonicus", formerly "Parus hudsonicus") is a small songbird, a passerine bird in the tit family Paridae.

Adults are 12.5–14.5 cm long with a weight of 7–12.4 g. They have grey-brown upperparts with a brown cap and greyish wings and tail; their face is mainly grey with white on the sides. Their underparts are white with brown on the flanks and a black throat. They have a short dark bill, short wings and a long notched tail.

Their breeding habitat is coniferous woods in Canada, Alaska and the northern edges of the United States. They nest in a hole in a tree; the pair excavates the nest, using a natural cavity or sometimes an old woodpecker nest. The pair remains together year round and may mate for life.

They are permanent residents, but sometimes move south in winter. They often forage with small flocks including other small birds in winter.

These birds forage on conifer branches or probe into the bark. They mainly eat insects and seeds. They will store food for later use.

The call is a husky "tsik-a-dee-dee", a variant on the call which gives chickadees their name.

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 (Gill "et al.", 2005). The American Ornithologists' Union has been treating "Poecile" as a distinct genus for some time already. The genus name "Poecile" has often been treated as feminine (giving the species name ending "hudsonica"); however, this was not specified by the original genus author Johann Jakob Kaup, and under the ICZN the genus name must therefore be treated by default as masculine, giving the name ending "hudsonicus" (del Hoyo et al. 2007).
