Population justification: Population genetics suggest that there has been a low historical population size (Bray and Hockey 2015). The population is now estimated at 6,670 individuals (Underhill 2014), roughly equivalent to 4,450 mature individuals.

Trend justification: The population is suspected to be increasing thanks to improved habitat management on near-shore islands, with a c.45% increase between 1979/1980 and the early 2000s (Underhill 2014, Loewenthal et al. 2015). There have been some local declines, but it appears possible that in a large number of cases these declines may be a result of individuals moving to adjacent habitats after a site has experienced some degradation (in 72% of cases where a site showed a decline, the adjacent areas showed a population increase) (Loewenthal et al. 2015).
