Population justification: The European population is estimated at 3,900-15,800 pairs, which equates to 7,800-31,700 mature individuals (BirdLife International 2015). Europe forms approximately 35% of the global range, so a very preliminary estimate of the global population size is 22,300-90,600 mature individuals, although further validation of this estimate is needed.
Trend justification: In Europe the population size is estimated to be decreasing by less than 25% in 12.6 years (three generations) (BirdLife International 2015).
