Occurring in many types of open habitats, this species is as familiar in arid deserts as it is in suburbs and city centers. It is best known for its remarkable ability to mimic other birds\' songs as well as mechanical noises, such as whistles, cars and trains. The Mockingbird often flashes the big white patches in its wings and tail to intimidate rivals and cats. It aggressively defends its nest, even from unwary humans, by dive bombing perceived intruders. Unmated males sing all though the night in the Spring.
