Canada jays are omnivorous. They hunt such prey as arthropods, small mammals including rodents, and nestling birds, and have even been recorded taking a magnolia warbler ( Dendroica magnolia) in flight. They have been reported to opportunistically hunt young amphibians such as the western chorus frog ( Pseudacris triseriata) in Chambers Lake, Colorado, and the long-toed salamander ( Ambystoma macrodactylum) in Whitehorse Bluff in Crater Lake National Park, Oregon. Canada jays have been seen landing on moose ( Alces alces) to remove and eat engorged winter ticks ( Dermacentor albipictus) during April and May in Algonquin Provincial Park. Researchers also found a Canada jay nest containing a brooding female, three hatchlings, and three warm, engorged winter deer ticks. Because the ticks were too large for the hatchlings to eat, it was hypothesized that the ticks may have served as " hot water bottles ", keeping hatchlings warm when parents were away from the nest.

How long do Canada jays stay in the nest?

Canada jay young are altricial. For the first three to four days after hatching, the female remains on the nest; when the male arrives with food, both parents help in feeding the nestlings. Nestling growth is most rapid from the fourth through the tenth day following hatching, during which time the female begins to participate in foraging. The parents carry food to the nest in their throats. The accompanying nonbreeding third bird does not help with feeding during this period but is driven away by the parents if it approaches the nest. Food is a dark brown, viscous paste containing primarily arthropods. Young Canada jays leave the nest between 22 and 24 days after hatching, after which the third bird begins to participate in foraging and feeding. Natal dispersal distance for the Canada jay is a median of 0.0 km for males, 2.8 km (1.7 mi) for females, and a maximum distance of 11.3 km (7.0 mi) for males and females.
