Distribution

Geography

Continents
Countries
Biogeographical realms

The Mindoro imperial pigeon is distributed throughout Mindoro, where sufficient closed canopy forests remain. They used to be found mostly in mountain forests above 1000m. However, in 1991, most of the observations were made in understory trees of the remaining low altitude forests of Mindoro (800-950m). IUCN assessed this bird as Endangered with an estimate of 600 - 1,700 mature individuals. This species is rare and uncommon, but known to be found more easily in Mount Ilong and Mount Halcon. Its habitat is threatened by logging, cultivation, deforestation and forest destruction.

Conservation actions proposed include more surveys to better understand population, distribution and ecology. Also, protect the remaining forest on Mt Halcon and lobby for improved protected status.
