Choiseul pigeon of Choiseul in the Solomon Islands off the coast of New Guinea, where the only specimens were collected. The specimens Meek acquired were likely collected near Choiseul Bay in the northern part of the island. The last reports of the species from the indigenous population came from the Kolombangara River. It also reportedly lived on the neighboring islands of Santa Isabel and Malaita, and it is suspected that it may once have lived on Bougainville Island. However, these reports were never confirmed and must be considered anecdotal. It would be considered very unusual if the Choiseul pigeon were truly endemic

It laid a single dark, cream-coloured egg in an unlined depression on the ground. The egg was about in size, which is considered small in proportion to the bird. The Choiseul pigeon was non-migratory and is thought to have lived on the forest floor in lowland forests, including coastal swampy areas that lacked mangroves. The Choiseul pigeon is usually considered to have been endemic to the island
