Lokala rörelser av grågäss Anser anser i södra Sverige utanför häckningstiden

Research output: Contribution to journalArticle

Abstract

During 1984–2009, Greylag Geese Anser anser were neck-banded at two lakes six kilometres apart in southwest Scania, southernmost Sweden: 2308 at lake Yddingen and 633 at Klosterviken (part of lake Bör-ringe). Through 2013 we recorded 51 132 and 29 937 re-sightings, respectively. We analyse the distribution patterns within Scania during the post-breeding months July–March. In spite of the short distance between the breeding sites, marked differences in the local distributions were found. In late summer and early autumn, Greylags from Klosterviken stayed longer inland close to the breeding lake than geese from Yddingen, the availability of good inland feeding sites close to Klosterviken explained the difference. In late autumn, when many resightings were made along the western coast, it seemed that the distance from the breeding lake explained some of the differences, geese from Yddingen dominated in the northern part, whereas geese from Klosterviken were found further south. There was also a time difference in that the birds from Yddingen moved to the coast earlier than those from Klosterviken.
