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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely 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:||Shirihai et al. (2001) estimated the population to exceed 10 million individuals, but in Europe, the breeding population is estimated to number 17-31 million breeding pairs, equating to 51-93 million individuals (BirdLife International 2004). Europe forms 75-94% of the global range, so a very preliminary estimate of the global population size is 54.3-124 million individuals, although further validation of this estimate is needed.
Trend Justification: In Europe, trends since 1980 show that populations have undergone a moderate decline (p<0.01), based on provisional data for 21 countries from the Pan-European Common Bird Monitoring Scheme (EBCC/RSPB/BirdLife/Statistics Netherlands; P. Vorisek in litt. 2008).
|Current Population Trend:||Decreasing|
