A medium-sized songbird, a bit more slender than a thrush and with a longer tail. Mockingbirds have small heads, a long, thin bill with a hint of a downward curve, and long legs. Their wings are short, rounded, and broad, making the tail seem particularly long in flight.Mockingbirds are overall gray-brown, paler on the breast and belly, with two white wingbars on each wing. A white patch in each wing is often visible on perched birds, and in flight these become large white flashes. The white outer tail feathers are also flashy in flight.
Song is a fairly slow-paced series of variable rich whistled notes, churrs, rattles, squawks, and other noises, often with phrases repeated; there appears to be little or no mimicry involved.
