What are some unusual things blue jays do?

Answer 1

This is a matter of opinion, of course. What is "unusual"? How about these: - Blue jays often gang up on larger birds, such as hawks, owls, eagles, and crows. This behavior, called "mobbing," tends to drive the predators away from the blue jays' nests. Other birds also do this, perhaps especially jays and crows. - In addition to the familiar, rasping "jay" calls, blue jays have a rather musical call that is usually rendered as "queeble-queeble." If you expect the screaming, raucous "jay-jay," you might not even believe that the "queeble-queeble" is coming from the same bird.
