The Gray Catbird is a handsome fellow. Easy to mistake for a blackbird at first glance. It is supposed to have a roufus (red-brown) area under the tail but I have not seen that.
The Gray Catbird, slate gray with a black crown.
The Catbird is so named for the mewing call which sounds rather like a cat meowing. Related to the Mockingbird and the Brown Thrush it also can imitate the cries of other birds, and is a fearless defender of its nest. It is a little shy and is more often heard than seen. I have seen very few but since setting out the suet feeder the Catbird has been a regular, although still a bit shy.
