Influence of Habitat and Food Resource Availability on Common Raven Nest Site Selection and Reproductive Success in Mediterranean Forests

Bird nest selection in forests can be influenced by the composition of key structural elements and resources. This has important consequences terms species population dynamics since it determine reproduction success. Here, we assessed Common raven nest-site reproductive success, how these might determined foraging behavior habitat structure. A previously documented breeding that exerts high predation pressure on young Spur-thighed tortoises (Testudo graeca) a Mediterranean forest was monitored. Generalized linear mixed models were performed to singularities trees with nests drivers success pairs ravens. The results showed density study area (0.8 pairs/km2), which selected taller areas higher bare ground cover for nesting. Nests spatially aggregated; occupied smaller territories intraspecific competition seemed relaxed, reflecting abundance food Most occasionally predated tortoises. Tortoises seem play part our area, associated availability/catchability illustrates tortoise distribution plays role ravens is mediated Understanding pivotal implementing appropriate management conservation strategies across their range, particularly where potentially affect threatened species.
