Population justification: Based on the probability of re-sighting ringed birds and observations between 2006-2008 the population has been estimated at 1,608 ± 326 mature individuals, or c.800 pairs, roughly corresponding with a 2008 estimate of 1,064 ± 304 individuals obtained through distance-sampling methods and range size analysis, thus a population of c.1,300 individuals is estimated, roughly equivalent to 860-870 mature individuals.
Trend justification: Annual census figures from 2002-2008 indicate that although there is some fluctuation the population is not currently declining (BirdLife International 2009) and there is evidence of recent population recovery (Ceia et al. 2011a). An annual survival rate was recently estimated at 0.62 which may have substantially contributed to the recent recovery of the population (Monticelli et al. 2010).
