About These Birds
Blue Jay
The blue jay is a bold, intelligent member of the corvid family known for its striking plumage and loud calls. Blue jays are important dispersers of oak trees, as they cache thousands of acorns each autumn. Their complex social behavior includes mimicking the calls of hawks to scare other birds from feeders.
