The Revillagigedo Islands or Revillagigedo Archipelago are a group of four volcanic islands in the Pacific Ocean, known for their unique ecosystem. They lie approximately 458 kilometres (285 mi) from Socorro Island south and southwest of Cabo San Lucas, the southern tip of the Baja California Peninsula, and 698 to 1,092 kilometres west of Manzanillo. Historically linked to the Mexican state of Colima, to which they were granted in 1861 to establish a penal colony, the islands are under Mexican federal property and jurisdiction.
Socorro Island is a volcanic island in the Revillagigedo Islands, a Mexican possession lying 600 kilometres (370 mi) off the country's western coast.

It is endemic to forests in the Sulu Archipelago in the Philippines. Until recently it was considered conspecific with the Mindanao brown dove and collectively called the dark-eared brown dove. Although threatened by habitat loss, the rate of loss significantly reduced from 2004 to 2007, and it was thus downlisted from Critically Endangered to Endangered status in the 2007 IUCN Red List.
