Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population [top]

Population: In Europe, the breeding population is estimated to number 58,000-77,000 breeding pairs, equating to 174,000-231,000 individuals (BirdLife International 2004). Europe forms 5-24% of the global range, so a very preliminary estimate of the global population size is 500,000-5,000,000 individuals, although further validation of this estimate is needed.
Population Trend: Stable
