Data Zone
Justification of Red List category
This species has an extremely large range and the population size is very large, hence does not approach threatened thresholds for the range or population size criteria. The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds 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 131,000-411,000 mature individuals, with 65,900-206,000 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 291,000-913,000 mature individuals, although further validation of this estimate is desirable. In Europe the trend for this species is not known (BirdLife International 2021). As no other data are available to derive trends, the global population trend for this species is unknown.
