Changes in abundance and breeding output of Greylag Geese Anser anser breeding in southern Sweden
Neck-banded Greylag Geese Anser anser from a population breeding in southwest Scania, southern Sweden, were studied to assess changes in the breeding population and breeding performance during 1984–2013.
