Population justification: Population genetics suggest that there has been a low historical population size (Bray and Hockey 2015). Based on data from shoreline counts and aerial surveys, the population is now estimated at 6,670 individuals (Underhill 2014), roughly equivalent to 4,450 mature individuals.
Trend justification: The population is thought 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). Analysis of data from the South African Bird Atlas Project 1 and 2 show an increase in range size and reporting rates for this species (Brown et al. 2019).
