The white-throated ground dove (''Gallicolumba xanthonura'') or ''paluman apaka'' in Chamorro is a species of ground dove in the genus ''Gallicolumba''. 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. *Habitat/Distribution: Forest - Subtropical/Tropical Moist, Shrubland - Subtropical/Tropical Moist, Artificial/Terrestrial - Plantations *Threats: Habitat Loss/Degradation, Invasive alien species, Harvesting ==Description== This species averages in length and weighs .〔''CRC Handbook of Avian Body Masses'' by John B.
