Population justification: In 2000, the population was estimated to number 15,000-50,000 breeding pairs (Aymí and Gargallo 2015), or 30,000-100,000 mature individuals. It is best placed precautionarily in the band 20,000-49,999 mature individuals.

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