Population justification: In Europe, the total population size is estimated at 72,100,000-114,000,000 mature individuals, with 36,000,000-56,700,000 breeding pairs (BirdLife International 2021), and comprises approximately 95% of the species' global range, so a very preliminary estimate of the global population size is between 75,900,000-120,000,000 mature individuals, although further validation of this estimate is desirable. The species' population in Europe is considered to have remained relatively stable over three generations (10 years) (BirdLife International 2021). As this region holds the vast majority of the species' global range, the global population size is considered to be stable over three generations.
