Пернатые хищники и их охрана (Oct 2018)
Study of Territorial Connections in Eagles by Color Ringing Method within the Program of the Russian Raptor Research and Conservation Network
Abstract
Large birds of prey make up about 40% of all ringed birds. The Steppe Eagle Aquila nipalensis (more than 700 individuals), the Imperial Eagle A. heliaca (more than 500 individuals), the White-tailed Eagle Haliaeetus albicilla (more than 350 individuals) are the leaders among them, taking into account data not included in the database for 2018 and unpublished data for 2017. At present, data on 93 ring recoveries and observations of large birds of prey in nature have been published. Colored rings made it possible to identify live birds in nature thanks to photo-documentation in 45 cases (48.4%). In other cases (51.6%), information was obtained as a result of finding dead or weakened birds during migrations and in wintering grounds, as well as of trapping birds in wintering grounds.
