Voice - The Gray Catbird is a good mimic. Its songs are a jumble of bits of other birds' songs, inventively arranged in series. It seldom repeats the same phrases, which sets it apart from both the Brown Thrasher and the Northern Mockingbird. It also utters hoots, cackles, whistles, a catlike meow from which it gets its name, and a questioning Mary? The alarm note is a loud check.
