This species is classified as Near Threatened because it is declining at a moderately rapid rate, owing to hunting and habitat destruction. If brown tree-snake Boiga irregularis were to be accidentally introduced to other islands in its range, the species may warrant uplisting to Vulnerable.

|Range Description:||Alopecoenas xanthonurus occurs widely in the Northern Mariana Islands (to USA) and on Yap in the Federated States of Micronesia. It has become extirpated from Guam (to USA) owing to predation by the introduced brown tree snake Boiga irregularis, and although single birds turn up once every few years, these are almost certainly individuals dispersing from the island of Rota, 60 km to the north (G. Wiles in litt. 1999). The highest population is probably on Rota where c.2,400 birds were estimated in 1982 (Engbring et al. 1982), but this population is declining as a result of predation by the invasive tree snake (H. Roberts in litt. 2009). It is fairly common on Saipan where up to 72 birds/km2 were recorded in limestone forest in 1991-1993 (Craig 1996). It is rare on Yap where the population was estimated at c.195 in 1984 (Engbring et al. 1990). |
