Population justification: In Europe, the breeding population is estimated to number 47,000-110,000 breeding pairs, equating to 141,000-330,000 individuals (BirdLife International 2004). Europe forms 25-49% of the global range, so a very preliminary estimate of the global population size is 300,000-1500,000 individuals, although further validation of this estimate is needed. National population sizes have been estimated at < c.100 breeding pairs in China and possibly c.100-10,000 breeding pairs in Russia (Brazil 2009).
Trend justification: The population is suspected to be fluctuating owing to fluctuations in rodent prey populations and weather conditions (del Hoyo et al. 1999).
