Mockingbird
(Mimus polyglottos)
Adopted in 1929.
The mockingbird was adopted as the Arkansas State Bird by the Forty-seventh General Assembly of 1929. The mockingbird can imitate the song of many other birds.
The Mimus polyglottos, as the mockingbird is known scientifically, is about ten inches in length, including its relatively long tail. It has a light gray coat and a whitish underside. Its wings and tail are darker gray with white patches. The male and females look alike. Juvenile has spotted breast.
The common mockingbird is a superb songbird and mimic. Its own song has a pleasant lilt, varied and repetitive. Often it will sing all night long, especially in bright springtime moonlight. Unmated male mockingbirds sing more than mated ones. Both sexes sing in the fall to claim winter feeding territories. These areas are often different than their spring breeding territories.
The song of the mockingbird is, in fact, a medley of the calls of many other birds, each repeated several times. It will imitate other species' songs and calls, squeaky gates, pianos, sirens, barking dogs, etc. Each imitation is repeated two or three times, then another song is started, all in rapid succession. In the above sample audio file, the songs of four distinct species were recorded in the span of about seven seconds. It is common for an individual bird to have as many as 25-30 songs in its repertory.
The mockingbird is also known as a fierce protector of its nest and environment. It is sometimes seen swooping down on a dog, cat or predator that may be venturing too close to the bird's protected territory.

- Scientists have found that female mockingbirds are attracted to males that can make the most different sounds.
- Mockingbirds are the state bird of Arkansas, Florida, Mississippi, Tennessee, and Texas and one of the few birds found in every kind of habitat, from desert to forest to city.
