Population justification: Porter and Suleiman (2013) estimated the population to number c.3,770 individuals based on analysis of transect data collected between 1999 and 2011, rounded here to c. 3,800 individuals. This is equivalent to c.2,500 mature individuals.
Trend justification: There are no new data on population trends, but the species is suspected to be stable (R. Porter in litt. 2012).
