Population justification: The European population is estimated at 20,000-41,700 pairs, which equates to 40,100-83,400 mature individuals (BirdLife International in prep.). Europe forms approximately 15% of the global range so a very preliminary estimate of the global population size is 267,000-556,000 mature individuals. Partners in Flight (2020) estimate the North American population at approximately 1,600,000 mature individuals, and the global population at 3,200,000 mature individuals. Given the wide range of the population estimates, the global population is placed in the band 250,000-3,200,000 mature individuals.

Trend justification: In North America, this species has undergone a large and statistically significant increase over the last five decades (on average 3.5% per year, equating to 56% over three generations; Partners in Flight 2020). Note, however, that these surveys cover less than 50% of the species's global range. In Europe, the breeding population size is decreasing by at least 30% over 13 years (three generations [Bird et al. 2020]) (BirdLife International in prep.). Overall, the global population is suspected to be stable.
