WG-EMM-17

In the 2013-14 reproductive season, the 26,000 pairs of Adélie penguins from Pétrel Island, Terre Adélie, failed to fledge their chicks. This catastrophic breeding failure resulted from two factors. First, the season saw an extreme sea-ice extent that forced Adélie parents to cover great distances to reach the open water during the incubation and early chick-rearing phases. The extended Read More
