Population justification: The population has been estimated at 3000-4000 pairs, equivalent to 6,000-8,000 mature individuals and c.9,000-12,000 individuals in total. Following the eradication of rats and mice from the island in 2015, it is possible that the population has increased due to an increase in range size, however surveys are needed to confirm this (T. Martin in litt. 2020).

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
