Population justification: A population estimate of at least 2,000 individuals, roughly equivalent to 1,300 mature individuals, is derived from Watling (1995), McCormack and Kunzle (1996), D. Watling ( in litt. 1999), Albar et al. (2009) and R. Malcolm (in litt. 2012). |
|
Trend justification: Although populations are thought to be stable on Rimatara and Teraina, and increasing on Atiu where it was recently introduced, invasive predators are likely to be causing a decline on Tabuaeran and Kiritimati, thus the overall trend is suspected to be a slow to moderate, continuing decline. |
