Greylag Goose (Anser anser)

These are frequently seen on the two Puffin colonies we visit Lundey/Akurey. When in flight they are usually in their V or line formation taking turns to lead. This formation that geese fly in is thought to reduce drag or air resistance thus making it more aerodynamic and allows them to fly long distances will little effort. Looks a little like the Pink footed Goose but they are found more inland whereas the Greylag Geese is found on the outskirts of Iceland. Thus, it will be this species we encounter on our tours.
