eastern Oregon, Idaho, Utah, eastern Arizona, northern New Mexico, Colorado,
portions of Great Plains and Great Lakes states, and New England. Winters mainly
through breeding range.
Habitat:
Found in coniferous
and mixed coniferous/deciduous
forests (primarily spruce),
including open and partly-open woodlands and around bogs. Often found around
campgrounds. In preliminary results of northern Idaho study, Gray Jays were
more abundant in fragmented than in continuous stands of old-growth forest.
Diet:
Omnivorous
. Feeds on insects, berries,
lichen
, mice, carrion
