Lammergeier (Gypaetus barbatus) Science Article 2
Old world vultures are thought to partition or competefor several types of resources. For example, in Africa,where vulture species diversity is highest, there isevidence that they compete for food (Petrides 1959,Konig 1983, Mundy et al. 1992, Hertel 1994). InEurope, Eurasian Griffon Gyps fulvus compete extensivelywith Lammergeiers Gypaetus barbatus for nestsites (Fernandez and Donazar 1991, Margalida andGarcia 1999, Bertran and Margalida 2002). Evidenceof interspecific aggression at nest sites also has beenobserved between Eurasian Griffon and CinereousVultures aegypius monachus (Blanco et al. 1997),between Eurasian Griffon and Egyptian VulturesNeophron percnopterus (Pascual and Santiago 1991),and between Cinereous Vulture and Bearded Vultures(Aykurt and Kirac 2001).
