Mimus is a bird genus in the family Mimidae. It contains the typical mockingbirds. In 2007, the genus Nesomimus was merged into Mimus by the American Ornithologists' Union. The genus name is Latin for "mimic".
The Nesomimus group is endemic to the Galápagos Islands. These mockingbirds were important in Charles Darwin's development of the theory of evolution by natural selection.
Previous to the merger between Nesomimus and Mimus scientists have proved in 1971 that both groups can produce hybrids. Robert I. Bowman and Anne Carter have studied a female Galápagos mockingbird and a male from the long-tailed mockingbird subspecies Mimus longicaudatus punensis that have interbred. They raised a hybrid offspring to adulthood.
