Canadensis Group - Gray Jay (Northern)

P. c. pacificus:

central Alaska through southwestern Alaska, USA, to central-coastal British Columbia, Canada

P. c. canadensis:

northeastern Alaska, USA, and northern Canada (Yukon and Northwest Territories south to southern British Columbia and southwestern Alberta, east across Canada to Quebec, and south into northern portions of Minnesota, Wisconsin, and Michigan, northern New York, and northern New England (all USA)

P. c. albescens:

western Canada east of the Rocky Mountains from northeastern British Columbia and northwestern Alberta south to north central United States (Black Hills, western South Dakota)

P. c. nigricapillus:

Eastern Canada (northern Quebec to Newfoundland and Nova Scotia)

Gray Jay (Rocky Mountains)

P. c. bicolor:

Rocky Mountains from southeastern British Columbia and southwestern Alberta (Canada) south to eastern Washington, central Idaho, and western Montana (USA)

P. c. capitalis:

Rocky Mountains of western United States (central Idaho and southern Montana to northern New Mexico, also disjunctly in east central Arizona)

obscurus Group - Gray Jay (Pacific)

P. c. griseus:

South-western British Columbia and Vancouver Island to north-eastern California

P. c. obscurus:

Coastal north-western US (Washington to north-western California)

Habitat

Coniferous and mixed forest of the taiga and high mountain elevations. Recorded at 2440 - 3050m in the Rocky Mountains.

Behaviour

They travel in small flocks and are very tame and often approach people.

Diet

Feeds on beetles, bugs, other insects, spiders, berries, fungi and sometimes on small birds, frogs, snakes, mice or other vertebrates. Takes also carrion. Produces a sticky saliva with which it glues together berries and other food items into balls for easier winter storage, like its relative the Siberian Jay.

Breeding

Breeding season starts already in late winter (February) and goes to April. Two birds stay permanently together. The nest is a bulky platform made of twigs and well insulated. It's placed 1.7 to 15m above the ground, close to the trunk of a spruce or fir tree. Lays 3 - 4 eggs.

Movements

A resident species. Most pairs stay in their territory for their whole life.
