Population justification: Both Moorea and Tahiti are now thought to hold populations of a few thousand individuals (J. C. Thibault pers comm in Spotswood 2011), therefore the total population is estimated to lie within the band 2,500-9,999 mature individuals. In 1973 there were an estimated 5,000-6,000 birds on Moorea with 2-3 birds per hectare in some valleys (Gibbs et al. 2001, Spotswood 2011).

Trend justification: It was reportedly very abundant in 1907, but is thought to have declined since 1900, though no systematic surveys have quantified changes and a survey of valleys in Tahiti suggested that populations remained stable in the 20^th century (Monnet et al. 1993 in Spotswood 2011). Nevertheless a slow population decline is suspected owing to habitat loss and degradation, including the spread of non-native vegetation. Further potential threats include predation by Swamp Harrier Circus approximans and feral cats, competition with non-native Red-vented Bulbul Pycnonotus cafer and Common Myna Acridotheres tristis, and predation of eggs by rats.
