Nest Site Selection and Breeding Success in ThreeTurdusThrush Species Coexisting in an Urban Environment

Research on three thrush species (Common Blackbird, Fieldfare, and Song Thrush) in the UNESCO World Heritage Site of Bardejov reveals that ecological segregation persists even in urban environments. Despite significant differences in nest placement—such as height, distance from town centers, proximity to human paths, and tree type preferences—the breeding success and predation rates were similar across species. Key factors influencing predation included nest location, tree height, and distance to human structures. This suggests that closely related species can coexist without competition, even in urbanized areas.
