Population justification: In 2007, the species was estimated by SEO (Sociedad Española de Ornitología/BirdLife in Spain) to number 5,000-20,000 individuals, roughly equivalent to 3,300-13,000 mature individuals.

Trend justification: The species's population is suspected to have recovered over at least the last 20 years (BirdLife International 2010), with evidence for this coming from increases in population estimates and the extent and quality of suitable habitat.
