Population justification: The global population is estimated at c.1% of that of P. bonelli (del Hoyo et al. 2006), putting it at 30,000-80,000 mature individuals.

Trend justification: In Europe the overall trend from 1980-2011 was increasing, based on provisional data for 27 countries from the Pan-European Common Bird Monitoring Scheme (EBCC/RSPB/BirdLife/Statistics Netherlands).
