Mockingbirds are a group of New World passerine birds from the Mimidae family. They are best known for the habit of some species mimicking the songs of other birds and the sounds of insects and amphibians, often loudly and in rapid succession.
There are about 17 species in three genera. These do not appear to form a monophyletic lineage: Mimus and Nesomimus are quite closely related; their closest living relatives appear to be some thrashers, such as the sage thrasher. Melanotis is more distinct; it seems to represent a very ancient basal lineage of Mimidae.
The only mockingbird commonly found in North America is the northern mockingbird (Mimus polyglottos). The Greek word polyglottos means multiple languages.
The song of the mockingbird is actually a medley of the calls of many other birds. Each imitation is repeated two or three times before another song is initiated. A given bird may have 30, 40 or even 200 songs in its repertoire, including other bird songs, insect and amphibian sounds, and even the occasional mechanical noise.
Part of the mockingbird’s advantage over other avians is physical; it uses more of the muscles in its vocal organ, the syrinx, than most other passerines do, many more than non-passerines like raptors or waterfowl. But the mockingbird also has a mind for music. It’s been theorized that this species has more brain matter devoted to song memory than most other birds do. Why does the mockingbird sing? The vocal mimicry trait seems to indicate that lyrical flow is an especially potent aphrodisiac in mockingbird circles, although some lonely males warble and whine the whole night through when unable to find a mate.
