Blue Jay – The Mysterious Migration Bird

The vibrant-colored, with a strident call, Blue Jay is common in backyards and forests throughout much of North America. This common, large songbird is familiar to a lot of people with its lovely perky crest, blue, white, and black plumage; and noisy calls.
Blue Jays are well-known for their intelligence, complex social systems, and tight family bonds. Their keenness for acorns is credited with assisting the spread of oak trees after the last glacial period. Generally, blue jays are natural forest dwellers, but they’re also highly adaptable and intelligent birds.
They’re a familiar and noisy presence around many North American bird feeders. The blue jay’s “Jay! Jay!” call is only one of a wide variety of sounds the bird employs, including outstanding imitations of several hawk calls. Therefore, the oldest known wild, banded Blue Jay lived to be at least 17 years and 6 months old. Blue Jays usually communicate with one another both vocally and with “body language,” using their crest.
Blue Jays are sometimes famous for eating eggs or nestlings, and it is this practice that has discolored their reputation. However, they’re largely vegetarian birds. Their diet mainly consists of acorns, nuts, grains, and seeds though they also eat small creatures such as caterpillars, grasshoppers, and beetles.
Blue Jay sometimes stores acorns in the ground and may fail to retrieve them, thus aiding in the spread of forests. The blue jay is common in much of eastern and central North America; blue jays are slowly extending their range to the Northwest. They’re fairly social and are usually found in pairs, in family groups, or in small flocks.
Most northern birds head south for the winter and join in large flocks of up to 250 birds to make the long journey. However, this migration is a bit of a mystery to scientists. Some birds winter in all parts of the blue jay’s range and some individual birds may migrate one year and not the next.
It is unclear what factors determine whether each blue jay or family decides to migrate. Blue Jays lower their crests when they’re feeding quietly with family and flock members or tending to nestlings. The higher the crest, the higher the bird’s aggression level and when a Blue Jay squawks, the crest is nearly always held up.
