Population justification: The global population size has not been quantified, but the species is reported to be generally uncommon (del Hoyo et al. 1999). In Europe the population is estimated at 50-80 pairs, which equates to 100-160 mature individuals (BirdLife International 2015).

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction.
