Factors behind the risk of crop damage caused by wintering and migrating large grazing birds (geese and swans)

Montras Janer, Teresa

Abstract

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.
