|Taxonomic Notes:||Bubo bubo and B. ascalaphus (Sibley and Monroe 1990, 1993) are retained as separate species contra AERC TAC (2003) and Dowsett and Forbes-Watson (1993) who include ascalaphus as a subspecies of B. bubo.|
|Red List Category & Criteria:||Least Concern ver 3.1|

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 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 19,000-38,000 breeding pairs, equating to 57,000-114,000 individuals (BirdLife International 2004). Europe forms 5-24% of the global range, so a very preliminary estimate of the global population size is 250,000-2,500,000 individuals, although further validation of this estimate is needed. National population estimates include: c.100-10,000 breeding pairs in China; c.100-10,000 breeding pairs in Korea; < c.100 breeding pairs in Japan and c.100-10,000 breeding pairs in Russia (Brazil 2009).|
Trend Justification: The population is suspected to be in decline owing to human persecution (del Hoyo et al. 1999).
|Current Population Trend:||Decreasing|
