Population justification: The total population is estimated to number c.40,000 individuals.
Trend justification: Direct counts, numbers of breeding females, a decrease in the area of occupancy and decline in the quality of habitat indicate that this species's abundance has at least halved over the last three generations, and that this decline is likely to continue (Garnett and Crowley 2000).
