The breeding biology of the Long-legged Buzzard (Buteo rufinus) was studied in the Evros area, north-eastern Greece in 1989, 1990, 1992 and 1993. The mean number of young fledged per pair per year was similar between years with an overall average of 0.93 (1.58 per successful pair). Often home range variables examined, the number of alternative nest sites and the extent of forest free areas in home ranges were significant predictors of nestling productivity. Aggressive interactions were observed with 18 bird species (of which 12 were raptors), most commonly with the Buzzard (Buteo buteo). Such interactions declined during the course of the season. Prey provisioning to nestlings was greatest in the morning and late in the afternoon declining in the intermediate period.
