is endemic to the tiny island of Rapa in the Tubuai Islands, French Polynesia
, where its population was estimated at 274 individuals (175-368) in 1989-19902
. Although it is probable that the area of available habitat has diminished during the 20th century and this may have caused a decrease in population, in 1991 there was thought to have been no serious decline since 19742
. The situation now is thought to be much the same3
, but the introduction of the Chinese guava Psidium cattleianum
may have provided an additional food source and be causing the population to increase, although surveys are needed to confirm this4
