Join an exclusive tour with an environmental specialist of an Eider colony in Þyrilsnes, a bird sanctuary in Hvalfjörður fjord where around 400 Common Eiders nest every year. The Eiders are protected and their eiderdown is a special and valuable product. When nesting in spring time, they lose their soft feathers and the farmers collect the down. Walk around the sanctuary, watch the birds and get hands-on experience and education on this remarkable bird.
