Gray Catbird

Gray Catbird - Dumetella carolinensis

Gray Catbirds are in the Mimidae family, which includes Mockingbirds and Thrashers. The genus name is Latin for "small thicket," a preferred habitat of the Gray Catbird.
Berries make up to 50% of the diet of the Gray Catbird. These birds visit my feeders. I put out oranges to try to attract Orioles, but the most consistent bird who eats the fruit is the catbird.
I heard this Gray Catbird before I saw the bird. The characteristic cat meow is only one of the songs in a wide repertoire. The Gray Catbird is a good mimic. A 4.5 minute recorded Gray Catbird song included 170 distinct phrases!
Gray Catbirds can recognize and remove parasitized cowbird eggs. This Gray Catbird was displaying in a territorial fashion. There was a Brown-headed Cowbird on a tall Spruce nearby and I wondered whether the display was for me or the cowbird?

The Gray Catbird winters in Mexico, Central America, and the Caribbean.
