This little Arctic seabird was once a common breeder with hundreds of pairs breeding in various places in N. Iceland for example Grímsey Island but since 1900 they have declined greatly, probably due to climate change. A couple of pairs may now breed here but where is unknown. They are mainly seen in the wintertime as the venture further south from their main breeding colonies in Greenland and Svalbard.
