Status summary
The Common Buzzard has shown a substantial eastward range expansion since the 1988–91 Atlas, and has arguably become the most abundant diurnal raptor in Britain (Clements 2002). The increasing trend identified by the CBC relates especially to the spread of range into central and eastern Britain, where CBC was more strongly represented. If anything, however, the upsurge has been ampified with the addition of the more geographically representative BBS data since 1994. The increase has been associated with rapidly improving nesting success, perhaps through reduced persecution, the recovery of rabbit populations from the effects of myxomatosis and release from the deleterious effects of organochlorine pesticides (Elliott & Avery 1991, Clements 2002). There has been widespread rapid increase across Europe since 1980 (PECBMS 2010).
