These jays inhabit deciduous, mixed, and coniferous forests, feeding mainly on seeds, invertebrates, and small vertebrates, with occasional human food.

As omnivores, they breed from spring to early summer, nesting in treetops or bushes with clutches of three to six eggs.

Both species are blue, black, and white with distinct black-banded tails and wings—a unique trait among American corvids.

[1][2] Crested jays have diverse vocal repertoires, from croaks and energetic calls to melodic sounds.

Both species are skilled imitators, mimicking buzzard calls, other birds, mammals, and even mechanical noises.

Only the Steller's jay extends into tropical regions, inhabiting cooler mountains as far south as Nicaragua.

[2] Steller's jays may migrate more widely after breeding seasons if food is scarce, with many juveniles moving to peripheral areas.
