Bewick's swans choose wintering areas based on the weather, shows long-term GPS data study

Bewick's swans fly less far during their autumn migration when the weather is warm. Climate change has therefore led to a shift in their common wintering areas. Now, for the first time, bird researchers from the University of Amsterdam (UvA) and the Netherlands Institute of Ecology (NIOO-KNAW) have been able to use long-term GPS data to pinpoint the specific choices that individual swans make. The results of their research were published today, Oct. 5, in the journal Global Change Biology.
