Justification of Red List category
This species qualifies as Critically Endangered owing to its extremely small breeding range and a projected extremely rapid population decline over three generations (70 years). Modelled population declines are a consequence of very low adult survival owing to incidental mortality in longline fisheries, compounded by low fledging success caused by predation of chicks by introduced mice.

Population size: 3400-4800

Population trend: Decreasing

Extent of occurrence (breeding/resident): 54,900,000 km2

Country endemic: Yes

Land-mass type - oceanic island
