Habitat use of flying subadult White-tailed Eagles (Haliaeetus albicilla): implications for land use and wind power plant planning
Large-scale construction of wind power plants may threaten large raptors at both individual and population levels. The most efficient way to prevent the negative effects of wind power plants is to avoid building on presumably high-risk sites, which requires an understanding of the movement patterns...
