Population justification: Brooke (2004) estimated the global breeding population to number 4,000,000-10,000,000 breeding pairs, equating to 12,000,000-30,000,000 individuals.

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
