Human Disturbances to Waterfowl
Annotated Bibliography
Because of the very narrow isthmus between the North Sea and the Nissum fjord and the considerable disturbance there by man and vehicles the geese often fed outside the area during day-time. During the feeding period at the Fiilso area the pink-footed geese were very sensitive to disturbance, (e.g. by farmers and vehicles). The "tolerance distance" was generally about 300 m, and only exceptionally 200 m during windy and rainy days. Geese usually fed and rested in the middle of the fields, far from roads, where they were most secure. Often disturbed at midday, they moved to the edges of the area into grassland where no farm work was being done.
