Population justification: Brooke (2004) claimed a population size of 800,000-1,000,000 individuals.
Trend justification: Population trends are unknown for this species. Rats predate on eggs and chicks at peripheral populations, but this may not impact the global population size (S. Oppel in litt. 2019). For example, nesting success is poor (17%) on Henderson Island, where rat eradication attempts have not been successful (Churchyard et al. 2013, Brooke 2019). However, the two largest colonies, on Ducie and Oeno, have been rat-free since 1997, with the latter now increasing in size (Brooke et al. 2018).
