Population justification: In Europe, the total population size is estimated at 16,300,000-29,200,000 mature individuals, with 8,190,000-14,600,000 breeding pairs (BirdLife International 2021), and comprises approximately 45% of the species' global range, so a very preliminary estimate of the global population size is between 36,200,000-64,900,000 mature individuals, although further validation of this estimate is desirable. In Europe, the species' population is considered to have remained relatively stable over three generations (10 years) (BirdLife International 2021). Based on these data, and the proportion of the species' global range that this region holds, the global population size is considered to be stable over three generations.
