Justification: 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: | In Europe, the breeding population is estimated to number 40000-140000 breeding pairs, equating to 120000-420000 individuals (BirdLife International 2004). Europe forms 5-24% of the global range, so a very preliminary estimate of the global population size is 500000-10000000 individuals, although further validation of this estimate is needed. |
