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.
This is a polytypic species, consisting of five subspecies:
- P. h. stoneyi:
- P. h. hudsonicus:
- Central Alaska and Yukon to Minnesota, Labrador and Newfoundland
- P. h. columbianus:
- Southern Alaska to southern Yukon, British Columbia, Montana and Washington
- P. h. farleyi:
- North-eastern British Columbia and Alberta to Saskatchewan and Manitoba
- P. h. littoralis:
- South-eastern Canada (southern Quebec) to Nova Scotia and north-eastern US
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.
Dense coniferous woodland, especially spruce and fir.
Monogomous. They nest in a tree hole which both sexes excavate.
The diet includes aphids, moths, insect larvae and conifer seeds.
(Similar to the call of a black-capped chickadee, but usually described as less melodious.)
