Population justification: The Partners in Flight Science Committee (2020a) estimate the global population to be approximately 2,300,000 individuals, which equates to 1,540,000 mature individuals. The European population is estimated at 84,900-142,000 pairs, which equates to 169,800-284,000 mature individuals (BirdLife International in prep.). Europe forms approximately 14% of the global range, so a very preliminary estimate of the global population size is 1,210,000-2,030,000 mature individuals, although further validation of this estimate is needed. It is placed in the band 1,200,000-2,100,000

Trend justification: Population trends for this species are difficult to assess due to its nomadic nature and annual fluctuations, which make fixed-area surveys such as the Breeding Bird Survey unreliable. However, using data from the Christmas Bird Count, the Partners in Flight Science Committee (2020b) estimated that there had been a 68.1% decline in North America during 1970-2017, equating to a 29.7% decline over 3 generations (14.49 years [Bird et al. 2020]). In Europe, the population trend is estimated to be fluctuating but stable in the long term (BirdLife International in prep.). The global population trend is therefore suspected to be declining at a rate of <20% over 3 generations.
