Population justification: Partners in Flight estimated the population to number fewer than 50,000 individuals (A. Panjabi in litt. 2008), thus it is placed in the band 20,000-49,999 individuals here.

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or current threats, however it is highly vulnerable to any future coastal development within its range (del Hoyo et al. 2005).
