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.
Turquoise-fronted Amazon
The turquoise-fronted amazon is one of the most popular pet parrots in the world, prized for its ability to mimic human speech and its engaging personality. In the wild, these sociable parrots roost communally in large flocks and fly in pairs to feeding sites at dawn. Habitat loss and trapping for the pet trade threaten wild populations.
