Blue Jays Interesting Behaviors
Blue Jays are extremely territorial, often diving at cats, dogs, even humans, who get near nesting and feeding territories.
Blue Jays can also imitate the sound of a Red-shouldered hawk which will scare other songbirds from feeders as the Blue Jay comes to feed.
Mainly found east of the Rocky Mountains, the Blue Jay has been declining in numbers, due in part from the reductions in forest and woodlands. Specifically oak trees, which provide the acorns Blue Jays prefer to eat.
