What is "gray catbird"

n. North American songbird whose call resembles a cat's mewing [syn: catbird, Dumetella carolinensis]

The gray catbird (Dumetella carolinensis), also spelled grey catbird, is a medium-sized North American and Central American perching bird of the mimid family. It is the only member of the " catbird" genus Dumetella. Like the black catbird (Melanoptila glabrirostris), it is among the basal lineages of the Mimidae, probably a closer relative of the Caribbean thrasher and trembler assemblage than of the mockingbirds and Toxostoma thrashers. In some areas it is known as the slate-colored mockingbird.
