Overview

Distribution

Range Description

This species 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 1989-1990 (Thibault and Varney 1991). 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 1974 (Thibault and Varney 1991). The situation now is thought to be much the same (J. Millet in litt. 2007), 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 this (P. Raust in litt. 2007).

Habitat and Ecology
Although once thought to be confined to remaining undisturbed forest fragments in valleys and mountains between 40 and 450 m (292 ha in 1991), and not able to utilise coastal vegetation or secondary forest (Thibault and Varney 1991), it has been seen in pine plantations and may feed on the introduced Chinese guava Psidium cattleianum (P. Raust in litt. 2007). It feeds on fleshy fruit and nectar from flowers (Thibault and Varney 1991).

Justification
This species is classified as Endangered because the population is very small (<250 mature individuals) and confined to undisturbed forest fragments on one tiny island. However, at present the population appears to be stable.
