The Gray Jay is found in northern forests of the United States and Canada year-round. They do not migrate and store food through the winter by sticking it to branches with their saliva. Their diverse diet ranges from berries to small animals. They have even been seen attacking large animals and eating blood-filled ticks off the backs of moose. These birds nest only in late winter, when temperatures can reach -20˚F (-29˚C). Their dense feathers, which they can puff up to cover their legs, help to keep them warm. In northern Eurasia, the Siberian Jay fills the same ecological niche, also using sticky saliva to glue food to branches.
