Habitat use by post-fledging white-tailed eagles shows avoidance of human infrastructure and agricultural areas
Abstract Habitat use studies provide invaluable information for the conservation of species that suffer from habitat loss or degradation. We used satellite telemetry to study the habitat use of white-tailed eagles (Haliaeetus albicilla) in relation to six habitat classes (artificial surfaces, agricu...
