The White-throated ground dove or paluman apaka in Chamorro (Gallicolumba xanthonura), is a species of dove in the Columbidae family. Their distribution is on the Northern Mariana Islands inhabiting the native forests. It has become extirpated from Guam (to USA) by predation from the introduced brown tree snake (Boiga irregularis). Single birds do turn up once every few years but are most likely individuals dispersing from the island of Rota. The birds are shy and tend to keep well hidden.
