Captive Blue Jays sometimes learn to imitate human speech and meowing cats.
The higher the crest, the higher the bird’s aggression level when a Blue Jay squawks, the crest is virtually always held up.īlue Jays have a wide variety of vocalizations, with an immense “vocabulary.” Blue Jays are also excellent mimics. When incubating, feeding nestlings, or associating with mate, family, or flock mates, the crest is held down the lower the crest, the lower the bird’s aggression level. There is apparently a lot of individual variation in how quickly young become independent.īlue Jays communicate with one another both vocally and with “body language,” using their crest. Young remain with and are fed by their parents for at least a month, and sometimes two months. The jays are usually farther than 75 feet from the nest by the end of the second day out of the nest. When young jays leave the nest before then, it may be because of disturbance. The brood usually leaves the nest together usually when they are 17-21 days old. Even when these birds beg loudly, parents may not feed them until they return to the nest this is the stage at which many people find an “abandoned baby jay.” If it can be restored to or near the nest, the parents will resume feeding it. Some individual nestlings begin to wander as far as 15 feet from the nest 1-3 days before the brood fledges. Female shares food gathering after this time, but male continues to provide more food than female. For the first 8–12 days after the nestlings hatch, the female broods them and the male provides food for his mate and the nestlings. Only the female incubates her mate provides all her food during incubation. They often mate for life, remaining with their social mate throughout the year. Blue Jays are known for their intelligence and complex social systems, and have tight family bonds. This common, large songbird is familiar to many people, with its perky crest blue, white, gray, and black plumage and noisy calls.
