The Socorro Dove (Zenaida graysoni) is a dove that is extinct in the wild. The last sighting in its natural habitat was in 1972. There are probably less than a hundred in captivity. A reintroduction is planned.

The Socorro Dove was endemic to Socorro Island in the Revillagigedo Islands. It was thought to have been extirpated by feral cats, but human predation and high levels of understorey grazing by sheep may also have been factors.

The binomial commemorates the American ornithologist and artist Andrew Jackson Grayson.

On October 30, 2006, in the London Zoo, a Socorro Dove was successfully bred. The bird's name is Arnie after Arnold Schwarzenegger. It is hoped that Arnie's descendants will someday be reintroduced into the wild.
conservation status of a species is an indicator of the likelihood of that species continuing to survive either in the present day or the future. Many factors are taken into account when assessing the conservation status of a species: not simply the number remaining, but the

extinction is the cessation of existence of a species or group of taxa, reducing biodiversity. The moment of extinction is generally considered to be the death of the last individual of that species (although the capacity to breed and recover may have been lost before this point).

Scientific classification or biological classification is a method by which biologists group and categorize species of organisms. Scientific classification also can be called scientific taxonomy, but should be distinguished from folk taxonomy, which lacks scientific basis.
