Population justification: The remaining population is assumed to be tiny, perhaps fewer than 50 pairs (Shirihai et al. 2009) or even fewer than 50 individuals and mature individuals, based on paucity of recent records (although these include 21 since 1983; Priddel et al. 2008, E. O’Connor in litt. 2012).

Trend justification: The population trend is unknown but it may well be declining owing to effects of rats, cats and feral pigs on Gau Island.
