Blue Jay
A harsh, ringing 'jaay-jaay-jaay'. Also mimics Red-tailed Hawk and other species convincingly. Gives soft, liquid 'bell' calls and gurgling whispers in flocks.

About These Birds
عقاب رخماء
The bald eagle is the national bird and symbol of the United States. Once endangered due to DDT pesticide use, it made a remarkable recovery and was removed from the endangered species list in 2007. These powerful raptors build the largest tree nests of any bird, some weighing over two tons.
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.
