Habitat
swamps, fern-covered hills, wooded areas such as the undergrowth of coconut groves, mixed horticulture, coastal forests and natural forest on limestone substrates.
Rarity Status
Currently this species is not classified as a rarity in this country OR information has not been updated.
Population
Estimated population is 680 - 2,600 (2010) and stable.
Status CR
Habitat destruction is the main threat. Feral cats are likely to cause some concern.
For more information see BirdLife International Species Factsheet.
Voice
A loud 'chack-chack' or a high-pitched chirp. Song not reported.

Subspecies
No subspecies.
Acrocephalus vaughani (Sibley and Monroe 1990) has been split into Pitcairn Reed-Warbler (Acrocephalus vaughani), Rimatara Reed-Warbler (Acrocephalus rimitarae) and Henderson Reed-Warbler (Acrocephalus taiti) following Sibley and Monroe (1993). Note that Collar et al. (1994) followed Sibley and Monroe (1990) in treating these three taxa as a single species, Pitcairn Reed-Warbler (Acrocephalus vaughani).
Has been treated as conspecific with Pitcairn Reed-Warbler (Acrocephalus vaughani) and Henderson Reed-Warbler (Acrocephalus taiti), but basic differences in sequence and pattern of leucistic plumage among the taxa suggest substantial genetic differentiation at species level. As they are separated by great distances of open ocean, gene flow among them is probably minimal.
