Satellite telemetry (ST) provides detailed information on the routes taken by migrating wildlife, the location of their stopover sites and the stopover durations. Comprehensive satellite tracking of Lesser Spotted Eagles (Aquila pomarina) since 1992 to the present day, has brought to light previously unknown details on the migration and wintering patterns as well a other aspects (e.g. habitat use and territoriality in the breeding grounds) in the life history of these birds.
