Jays are medium-sized, colorful, and noisy birds that belong to the crow family, Corvidae. There are about 30 to 45 species of jays globally, and 12 of these can be found in North America.
They can be classified into three groups for simplicity. Old World jays are brown-colored from Afro-Eurasia. New World jays are the American Jays and are generally blue, and Gray Jays only have three species in the world.
Jays are shy birds even though they make high, screeching noises in woodland forests. When you hear a jay, it is often because you’ve disturbed them, and now they’re on high alert. They notify other jays and start to move off.
Research has shown that jays can hoard thousands of acorns and store them for winter. While they also feed on other seeds and berries and even small animals like nestlings and bats, they really prefer to eat acorns! They will hold the nuts with their feet and then, with their strong bills, crack the shell open.
Jays are monogamous, meaning they mate for life. The two of them work together to build their nest and become territorial when guarding their growing family.
A group of jays may be called a “band”, “cast”, “party”, and “scold”. This is because they are usually found in noisy groups.
Attract Jays to your backyard with nuts like acorns, peanuts, and sunflower seeds. Just be careful not to linger in their territory while they’re feeding because they can get aggressive.
