Population justification: The European population is estimated at 111,000-230,000 pairs, which equates to 222,000-460,000 mature individuals (BirdLife International 2015). Europe forms approximately 5% of the global range so a very preliminary estimate of the global population is 4,400,000-9,200,000 mature individuals, although further validation of this estimate is needed. The population is therefore placed in the band 4,000,000-9,999,999 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). Note, however, that these surveys cover less than 50% of the species's range in North America. The European population trend is estimated to be fluctuating (BirdLife International 2015).
