The Blue Jay

Blue jays can be seen throughout America and the southern part of Canada. They live in parks, yards, forests, or anywhere there are oak trees, since acorns are their favorite food.

Blue jays also eat fruits, nuts, seeds, insects, and some small animals like mice and frogs. Blue jays don't like sharing food, and will chase other animals away from food sources.

Blue jays nest in trees. They make their homes out of sticks, grass, paper, lichen, roots, and/or other materials. Females lay four to six eggs at a time. Blue jay eggs are greenish with brown spots. Baby jays fledge at about three weeks.

Blue jays do an interesting thing called "anting" when they are molting: they pick up ants and rub them on their bodies. Nobody's really sure why they do this, but the best guess is that anting soothes a blue jay's skin. Sometimes they'll "ant" with other items like rotten fruit.
