#80 Blue Jay Colorful and noisy, Blue Jays are common visitors to the woodlots and backyards of the eastern United States. Members of the corvid family, they’re intelligent and adaptable. They regularly visit bird feeders to eat peanuts or sunflower seeds, but they also love acorns, a taste that is credited with helping spread oak trees after the last glacial period. They also mimic the calls of hawks, either as a signal to other jays that a hawk is present or to trick other species into believing one is.
