Abstract
In 2015 and 2016 four Lesser White-fronted Geese (Anser erythropus), a globally threatenedspecies, were caught and tagged during spring migration representing nearly 10% of the entire Swedish breeding population at the time. Two of the birds were followed over more than one season. Tracking data revealed an unexpected wide network of migration corridors and staging sites. Autumn and spring migration differed by stepping-stone sites and migration speed. So far
unknown key stopover sites were discovered in Denmark, northern Germany, and Sweden. By using dynamic Brownian bridge movement models, the potential areas that Lesser Whitefronted Geese used during migration are described and conservation implications spotlighted.
This study provides another important piece of the puzzle describing the migration of Lesser White-fronted Geese in Western Europe.
