Blue Jays are beautiful but noisy birds. Their raucous call often warns other birds of danger nearby. Some of the eastern ones migrate while others stay in one locale. You will find blue jays as far north as Canada and also in the south of Florida.
Coloration - both male and female are similar in colors and plumage.
Habitat - they are commonly found in residential areas of towns and cities but like to hang out in trees where they build their nests.
Diet - they eat mainly seeds and nuts and love to dine on acorns. This last accounts for the wide spread forests of oak trees.
Behavior - blue jays are quite aggressive and are known to raid the nests of other birds, so you often will find other birds attacking the jays to keep them away.
