Backyard Winter Birds | Blue Jay Profile The Blue Jay, a common songbird, is familiar to many in northern Illinois. Native to North America, at least some Blue Jays stay around all winter. They are very aggressive and sometime attack other birds. Still, they are beautiful against the snow. They mainly feed on nuts and seeds so they show up every day to the bird feeder; particularly, when snow covers the ground. Blue Jays are well known for their intelligence and tight family bonds. Thousands of Blue Jays migrate in flocks along the Great Lakes each year, but little is known about their migration. Young jays are more likely to migrate than adults, but adults also migrate. No one has determined why they migrate, when they migrate, or why some migrate while others do not. For the whole story with all images, see Backyard Winter Birds | a 7 Image Story.
