Population justification: There may c. 29,573 breeding pairs (Muñoz and P. Hodum unpubl. data), which would imply around 150,000 individuals.

Trend justification:

Trends are unknown, although long-term breeding season monitoring on Robinson Crusoe and Santa Clara islands (2002-present) and Mocha (2010-2016) suggest stable populations. In addition, a comparison of burrow count data from 2003 and 2016 for all colonies in Juan Fernández indicates that burrow numbers have remained stable during that time (P. Hodum unpubl. data). Further research is needed to determine if introduced predators and herbivores on Robinson Crusoe Island, rats Rattus spp., dogs and feral cats (Felis catus) and harvesting of chicks on Isla Mocha, as well as fisheries bycatch are having any impact.
