Population justification: The population is estimated to number 250-999 mature individuals (G. Kirwan in litt. 2007). This equates to 375-1,499 individuals in total, rounded here to 350-1,500 individuals. Porter and Suleiman (in prep.) estimated the population at c.300 pairs or 1,400 individuals; however, the analysis of transect data collected up to 2004 suggests that the population may be higher than this, with a likely minimum of 3,000 individuals (R. Porter in litt. 2012), although a lower estimate is retained here pending the finalisation of this analysis.
Trend justification: There are no new data on population trends, but the species is suspected to be stable (R. Porter in litt. 2012).
