The Socorro dove (Zenaida graysoni) originally lived on the remote island of Socorro in the Revillagigedo Islands, off the west coast of Mexico, but became extinct there in the 1970s due to predation by introduced rats and domestic cats which were brought to the island as pets by the Mexican Navy. Conservation programmes are planning to return the doves to their original habitat. The male has deep cinnamon head and underparts, with black streak on lower ear-coverts, blue-grey nape and iridescent pink neck patch. Female and juvenile coloration is slightly duller.
