Population justification: In Europe, the breeding population is estimated to number 0.76-1 million breeding pairs, equating to 2.28-3 million individuals (BirdLife International 2004). Europe forms 25-49% of the global range, so a very preliminary estimate of the global population size is 5-10 million individuals, although further validation of this estimate is needed.
Trend justification: The population is declining owing to habitat destruction and alteration. It is also potentially threatened by over-hunting, pollution (especially acid rain) and climate change (del Hoyo et al. 1994).
