Northern Mockingbirds are named for their uncanny ability to copy, or mock, other bird songs and sounds. Besides a repertoire that may include up to 200 (!!) different songs and sounds, male Mockingbirds are among the loudest and most constantly vocal of birds. Unpaired males are especially known to sing all day and long into the night. Check out this neat audio clip of a Northern Mockingbird imitating the calls of SIX different species (Eastern Bluebird; Northern Cardinal; Northern Flicker; Yellow-breasted Chat; Carolina Wren; and American Robin)!
