The Long-tailed Mountain Pigeon has been split into two species:

Gymnophaps is a genus of bird in the pigeon family Columbidae; it includes four species, all called Mountain pigeons.

Males and females look mostly alike, though the female Papuan Mountain Pigeon has a grayer belly than the male.

Mountain pigeons move around a lot and are often seen flying, usually in flocks of at least ten or as many as a hundred or more birds.

The Pale Mountain Pigeon (Gymnophaps solomonensis) is a species of bird in the Columbidae family.

The Papuan Mountain Pigeon has a range in between the others; it lives on the island of New Guinea and on nearby smaller islands.

Mountain pigeons live in the forested hills and mountains of certain islands in eastern Indonesia and in the region of Melanesia.

Two species are island endemics: the Buru Mountain Pigeon is endemic to the Maluku Islands, and the Pale Mountain Pigeon is endemic to the Solomon Islands.
