Population justification: The European population is estimated at 37,200-79,200 pairs, which equates to 74,400-158,000 mature individuals (BirdLife International 2015). Europe forms approximately 15% of the global range, so a very preliminary estimate of the global population size is 496,000-1,050,000 mature individuals, although further validation of this estimate is needed. Rich et al. (2004) estimated the global population to number > c.500,000 individuals which would equate to approximately 333,000 mature individuals. The population is therefore placed in the band 300,000-1,000,000 mature individuals.

Trend justification: This species has had stable population trends over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). In Europe the population size is estimated to be fluctuating (BirdLife International 2015).
