Migration of fennoscandian lesser white-fronted geese Anser erythropus mapped by satellite telemetry

摘要

Since staging and wintering sites of the globally threatened lesser white-fronted goose Anser erythropus are poorly known, satellite transmitters were used to map autumn and winter migration routes of four individuals. After having spent c. 2 weeks at a post-moulting staging place in Finnmark, north Norway, all individuals flew directly to the Kanin Peninsula, northwest Russia. Later, two of the geese migrated along a westerly route to East Germany, where one of the geese disappeared, and to Hungary and Greece. The other two individuals followed an easterly route. One was shot close to the west side of the Ural mountains, whereas the other individual disappeared in the Ob valley, Russia. The results might indicate a higher hunting pressure along the eastern route than along the western route.
