What habitat do blue jays live?

Answer 1

website states:

Blue Grouse breeds in montane forest communities with relatively open tree canopies, and may occupy adjacent shrub-steppe habitat out to 2 kilometers from the forest edge. Breeding habitat may be dominated by Ponderosa Pine, Douglas-fir, or true fir species, sometimes with an aspen component. This species winters almost exclusively in montane conifer forests, often at high elevations (Schroeder 1984, Cade and Hoffman 1990, Zwickel 1992).

Answer 2

Being an adaptable species, the bluejay can be found in forests, or suburban lawns. Very aggressive birds, blue jays often will dominate other species at feeders.
