Value of species
Remarks
Detail
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. The global population is estimated to number approximately 3,000,000 individuals which equates to 2,000,000 mature individuals (Partners in Flight Science Committee 2013). The European population is estimated at 54,700-186,000 pairs, which equates to 109,000-372,000 mature individuals (BirdLife International 2015). Europe forms approximately 14% of the global range, so a very preliminary estimate of the global population size is 391,000-1,330,000 mature individuals, although further validation of this estimate is needed. Trend Justification: This species has undergone a large and statistically significant decrease over the last 40 years in North America (71.2% decline over 40 years, equating to a 26.7% decline per decade; data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). Note, however, that these surveys cover less than 50% of the species's range in North America. In Europe, the population trend is estimated to be fluctuating (BirdLife International 2015).
