Population justification: Four detailed surveys between 2001 and 2012 plus additional search efforts failed to find any birds at all, so the remaining population is likely to be very small (plausibly with fewer than 50 mature individuals), with potential extirpation from its stronghold in Viti Levu (Watling 2013).

Trend justification: Ongoing logging and road construction causes habitat loss and is likely to increase rat populations, both of which may lead to population declines. The species is apparently harder to find now than it was formerly.
