foraging ecology - life history - epidemics
Bewick's swans (Cygnus columbianus bewickii) breed in Siberia and winter in Western Europe. Visiting crowed areas like the Netherlands result in conflicts between Bewick's swans and humans, because of for instance foraging on agricultural lands and the potential spread of avian influenza. In this project we investigated space use and foraging in winter by the Bewick's swans. We equipped 12 Bewick's swans with GPS-loggers to track then throughout the winter. We related their movements to both their infection status of a low-pathogenic avian influenza and to vegetation quality and growth.
