Population justification: More than 99% of the global population now breeds on Lord Howe Island, where approximately 32,000 pairs nest on Mt Gower and Mt Lidgbird with some additional birds nesting on the lower slopes and Northern Hills (Bester 2003). A small but increasing (c.250 pairs in 2016) population now breeds on Phillip Island after their discovery in the 1980s (Hermes et al. 1986, Carlile et al. 2021). Overall, the contemporary population is estimated to number 66,500-100,000 mature individuals, with a best estimate, from Carlile et al. (2021), of 83,000. Historically, a population on Norfolk Island was thought to have numbered about a million pairs in the late 18th century (Medway 2002) and was probably even larger 600 years earlier, before the arrival of Polynesian settlers (Lombal et al. 2017).

Trend justification: The population trend of this species is inferred to be stable (Carlile et al. 2021) in the absence of plausible threats causing declines. 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). The population on Phillip Island has increased from about 20 pairs in 1985 when discovered (Priddel et al. 2010), to 250 pairs in 2016. Overall therefore the population appears to be stable (Carlile et al. 2021).
