General Description: | |||||||||||
Global Reproduction Comments: | Clutch size 2-5 (usually 3-4). Incubation 16-18 days, by female. Young tended by both adults, capable of first flight when about 15 days old. In Ontario and Quebec, broods broke up in June, when the young were 55-65 days old; dominant brood member expelled siblings from natal territory, shared in food stored by parents (Strickland 1991). | ||||||||||
Global Ecology Comments: | Occupies, permanent, all-purpose territory. Usually seen in small family groups or in pairs. Gray Jays have home ranges of about 65-130 hectares in Ontario (Rutter 1969). | ||||||||||

Habitats: (Type / Subtype / Dependence) |

Global Habitat Comments: | Coniferous and mixed coniferous-deciduous forest (primarily spruce), including open and partly open woodland and around bogs (AOU 1983). Often around campgrounds. BREEDING: Usually nests in a conifer, 1-9 m (usually 2-3 m) above ground. | ||||||||||
Food Habits: |
Carnivore: Adult, Immature
Frugivore: Adult, Immature Granivore: Adult, Immature Invertivore: Adult, Immature |

Global Food Habits Comments: | Omnivorous. Feeds on insects, berries, lichen, mice, carrion, scraps from campsites. Probably eats birds' eggs. Stores hundreds of food items per day during summer; apparently relies heavily on that food in winter; food is cached (scatter-hoarded) in arboreal sites such as under a flake of bark, in a clump of lichen, or in a conifer needle-cluster (Condor 94:995-998). | ||||||||||
