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.
Black-headed Jay
The Black-headed Jay is a medium-sized, boldly patterned jay with a black head and face, gray body, and bright blue-and-white wing markings. It inhabits coniferous and mixed forests of the Himalayas from northern Pakistan through India to Bhutan, typically at elevations between 1,500 and 3,500 meters. It feeds on acorns, seeds, insects, and small vertebrates, and is known to cache food for winter.
