Socorro dove

The Socorro dove or Grayson's dove (Zenaida graysoni) is a dove species which is extinct in the wild. It was endemic to Socorro Island in the Revillagigedo Islands off the west coast of Mexico. The last sighting in its natural habitat was in 1972 and it survives only in captivity. A reintroduction program is being prepared. It is a close relative of the mourning and eared doves, particularly the former, and was at one time considered a subspecies. In captivity, it hybridizes with the former and almost all privately owned birds as well as several of the captive breeding program birds are known or strongly suspected to be hybrids. These are excluded from the reintroduction program as there is evidence of unique adaptations in the Socorro species. The scientific name commemorates Zénaïde Laetitia Julie Bonaparte and the American ornithologist and artist Andrew Jackson Grayson.
