Second is the bird's variety of raucous calls and songs which often serve as alarms for other birds when a hawk or a cat or some other predator is in the area. They possess a wide variety of calls, and are able to mimic other birds. One of these blue beauties who visits my platform feeder daily has this trick mastered. It sounds almost exactly like the hawk, but the copied, jay version doesn t have the weight of the real hawk voice. I haven t been able to determine if using this hawk call affords the jay any feeding advantages.
Blue jays are also notorious raiders of other birds' nests.
They will attack any bird in the immediate vicinity of their nest in the spring, as well as steal eggs, young birds and even nests. They like robin nests and often appropriate them for nesting. The inside of the nest is usually lined with grass. The Blue Jay is a member of the Corvidae family which includes ravens, magpies, crows and a variety of other jays scattered throughout both North and South America. Blue jays live throughout eastern North America from Manitoba all the way to Florida and the Gulf of Mexico.
