Data Zone
Justification of Red List category
This species has an extremely large range and the population size is extremely large, hence does not approach threatened thresholds for the range or population size criteria. The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion. For these reasons the species is evaluated as Least Concern.
Population justification
In Europe, the total population size is estimated at 935,000-1,870,000 mature individuals, with 467,000-932,000 breeding pairs (BirdLife International 2021), and comprises approximately 55% of the species' global range, so a very preliminary estimate of the global population size is between 1,700,000-3,400,000 mature individuals, although further validation of this estimate is desirable. The species' population in Europe is considered to have undergone a suspected increase over three generations (10 years) (BirdLife International 2021). As this region holds the majority of the species' global range, the global population size is considered to be increasing over three generations.
