Typically found in dense shrubbery and forest edge, the Gray Catbird can often be secretive and hard to see. In the southwest, it is found primarily in dense riparian vegetation. The bulky nest is made of grass and twigs and placed in a low bush. Its blue-green eggs make it difficult for cowbirds to hide their spotted brown eggs in the Catbird nest. During the winter, fruits and berries are a favorite food, but during the summer insects and spiders are preferred. Occasionally it mimics parts of other bird species\ songs. '
The four-digit banding code is GRCA.
