SEAHOUSES, ENGLAND - MAY 16: Puffins return to their summer breeding grounds on the Farne Islands as National Trust rangers carry out a Puffin census on May 16, 2013 in the Farne Islands, England. A census is carried out every five years with the last one in 2008 recording 36,500 pairs of puffins. The Farne Islands, offer good protection for the birds to nest, providing excellent sources of food, and few ground predators, despite this rangers fear that the extreme winter could impact on breeding numbers.
