Blue Jay
A crested blue corvid that caches acorns, imitates hawks, and maintains a surprisingly complex neighborhood social life.
Artwork inspired by John James Audubon
Blue jays are intelligent corvids of eastern forests, suburbs, and parks. Their blue is structural rather than blue pigment, produced as feather microstructure scatters light. Black facial markings vary among individuals and may help jays recognize one another.
In autumn they carry and bury acorns, failing to retrieve enough that some grow into trees. Calls range from metallic jeers to bell-like notes and convincing hawk imitations, so identifying the bird by voice takes more than learning one sound.

Good to know
Blue jays have many calls, including convincing hawk imitations, so one sound is not enough for identification. Native oaks support their acorn-caching behavior more durably than repeated handouts.
