mockingbird

n. (Zool.), A long-tailed gray-and-white songbird of North America (Mimus polyglottos), remarkable for its exact imitations of the notes of other birds. Its back is gray; the tail and wings are blackish, with a white patch on each wing; the outer tail feathers are partly white. Originally its range was confined mostly to the southern states, but by late 19th century it had migrated as far north as New York.
