Behavior
Blue jays are very aggressive and noisy birds,driving other birds away from food sources and their territories. In the winter, Blue jays hide far more food than they can eat, perhaps to remove food from their territories to discourage intruders. They are also partially migratory, and in the fall they can be seen traveling in flocks of more than a hundred birds. (Sanford 1984)
Communication and Perception
Blue jays use bobbing motions when courting and when fighting. A signal of submission may be the "body-fluff" when the bird crouches down and fluffs up its feathers, holding the crest erect.
Blue jays have many calls. The one that is probably most familiar is the "jay" call for which it is named. This probably attracts other jays to join a flock or serves as an alarm call. Another call sounds like a rusty pump handle, and another sounds like a bell. Blue jays also make rattling sounds. In the spring you can hear very soft singing.
