Blue Jay (Cyanocitta cristata) Description Blue jays are bright blue medium sized birds with blue head crests, black wing markings and black necklaces. Life History. Bright and bold, blue jays often travel in noisy family groups in late summer and fall. Their arrival at a bird feeder tends to clear the area of smaller birds. Blue jays are known to eat the eggs and young of other birds and often frighten the adults off the nest by imitating the call of a hawk. Groups of blue jays often attack owls, which they consider a threat. Blue jays are one of the few birds that store food for use at another time. Blue jays eat insects and other invertebrates, small vertebrates including nestlings of other species, carrion, eggs, fruits and seeds.
