Chiefly oak forest, but now also city parks and suburban yards, especially where oak trees predominate.


Resident east of Rockies, from southern Canada to Gulf of Mexico. Slowly encroaching westward.


Although sometimes disliked because they chase smaller birds away from feeders, Blue Jays are among the handsomest of birds. They often bury seeds and acorns, and since many are never retrieved they are, in effect, tree planters. They regularly mob predators, and their raucous screaming makes it easy to locate a hawk or a roosting owl. Although seen all year, they are migratory and travel in large loose flocks in spring and fall. Birds from farther north replace local populations in winter.


4-6 brown-spotted greenish eggs in a coarsely built nest of sticks, lined with grass and well concealed in a crotch or forked branch of a tree, often a conifer.
