Abstract

This research article studies sources, forms and levels of limiting aspects that influence biological parameters of sedentary species of cinereous vultures (Aegypius monachus), Eurasian griffons (Gyps fulvus), lammergeyers (Gypaetus barbatus) as well as nomadic and nesting species of Egyptian vulture (Neophron percnopterus) in the territory of Azerbaijan Republic. Monitoring and logging were conducted in 43 nesting spots belonging to 4 species. It has been revealed that there are many satisfactory nesting biotopes in Azerbaijan and they are not limiting factors for scavenger birds. The main limiting factor is food shrinking. With the purpose of optimizing food supply during breeding periods supplementary feeding was organized in the nesting spots of these species. This resulted in increase of pairs participating in breeding by 1.2–1.6 times in the populations. On the basis of laws of Azerbaijan Republic on protection of biodiversity it was possible to lower and eliminate effects of anthropogenic factors by ensuring proper protection of these species and organizing landscapes for usage of planting, industry and recreation considering living conditions of the species as well as increasing knowledge of local inhabitants. All these activities will ensure stable and sustainable development of necrophage bird populations in Azerbaijan, also contributing to their protection in a global scale.
