Justification of Red List category
The majority of the population of this species occurs on the island of Saipan, where the Brown Tree Snake (Boiga irregularis) may possibly be in the process of becoming established. This would lead to an extremely rapid population reduction in the near future and the species is precautionarily classified as Critically Endangered. Fortunately, there has been little evidence of Brown Tree Snakes colonising any islands outside of Guam, and this species might be down-listed after a more detailed assessment of this threat.

Population trend: Decreasing

Extent of occurrence (breeding/resident): 400 km2

Country endemic: Yes
