Distribution

In most boreal regions of North America, meaning the coniferous forests of Canada, Alaska and northernmost parts of some US states such as Maine and Minnesota. Additional "islands" of habitat in the fir forests on mountain ranges in New York and New England.

Taxonomy

This is a polytypic species, consisting of five subspecies[1]:

  • P. h. stoneyi:
  • Northern Alaska to northern Yukon and north-western Mackenzie
  • P. h. hudsonicus:
  • P. h. columbianus:
  • P. h. farleyi:
  • P. h. littoralis:

The scientific name of this species has in the past been given as both Parus hudsonicus and Poecile hudsonica but most world wide checklists currently use Poecile hudsonicus.

Habitat

Dense coniferous woodland, especially spruce and fir.

Behaviour

Breeding

Monogomous. They nest in a tree hole which both sexes excavate.

Diet

The diet includes aphids, moths, insect larvae and conifer seeds.

Vocalisation

Call: tsik-a-dee-dee.

(Similar to the call of a black-capped chickadee, but usually described as less melodious.)
