Gray Catbird Singing
24 June 2016
Unlike their classic cat-like “meowing call” the Gray Catbird sings much like a Mockingbird – a close relative. Unlike the Mockingbird the Catbird is often hidden in heavy cover and you probably hear its song more often than you know. But when you hear the “mewing call” there is no doubt of the Catbird’s presence.
