Sammanfattning

Populations of large grazing birds have increased in Europe over the last decades with increased crop damage as a result. In this essay, I review studies investigating factors affecting choice of staging site, choice of field within staging sites and, when grazing by geese and swans cause damage. At the large spatial scale, I review the factors driving attractiveness and popularity of staging sites, and factors impacting changes on this attractiveness. At the small spatial scale, I review studies investigating foraging strategies in relation to food and field preferences, and how these may change within and across years.
