Population justification: During the 2002 breeding season the estimated the Lord Howe Island population was estimated at just over 32,000 breeding pairs (Bester 2003). Current estimates for the Phillip Island population are at 10-100 pairs (Priddel et al. 2010) with 250 burrows counted in 2011 (N. Carlile unpub. data).

Trend justification: Surveys have determined that the species's distribution is likely to have increased since the eradication of pigs on Lord Howe Island and it appears to be establishing itself in the lower elevations south of Mt Lidgbird (Bester 2003).
