The Greylag Goose (Anser anser) is a large, gray-brown goose with a characteristic orange beak and pale belly, often seen grazing in fields or resting near water. In Faxaflói Bay and surrounding areas in Iceland, these geese are a familiar sight, as Iceland hosts a significant breeding population. Greylag Geese are herbivorous, feeding on grasses, grains, and aquatic plants, and they often forage in agricultural fields. They are partially migratory, with many Icelandic populations traveling to the British Isles during winter. Studying Greylag Geese in Faxaflói Bay provides insights into migratory behavior, habitat preferences, and the balance between agricultural practices and wildlife conservation.
