Samenvatting

In order to gain a better understanding of the epidemiology of Avian Influenza in their natural hosts, more insight in the effects on its natural hosts should be gained. The aim of this research is to gain insight into the effects of a LPAI infection on winter movement and the influence on the preparation for migration (especially the fuelling rate) of Bewick's swans. This is done within the framework of a larger research, which aims to interpret the potential role of wild birds in the distribution of LPAI viruses, conducted by the Netherlands Institute of Ecology (NIOO).
