"Black-capped Chickadee," Wikipedia, the free encyclopedia. The black-capped chickadee is found from coast to coast, from the northern half of the United States in the south, to James Bay, the southern edge of the Northwest Territories and the Yukon, and the southern half of Alaska in the north. In winter it may wander outside this range, both to the north and south. Its preferred habitat is deciduous woods or mixed (deciduous/coniferous) woods. It is also found in open woods, parks, and suburban areas. Habitat segregation is the principal factor that separates the black-capped chickadee from both the boreal chickadee in the north and the chestnut-backed chickadee in the Pacific northwest (these two species prefer strictly coniferous forests). Altitude also separates the black-capped chickadee from the (higher) mountain chickadee in the western mountains and the (lower) Carolina chickadee in the Great Smokey Mountains.
