Adélie penguins

The Adélie penguin is a sea-ice obligate species so ocean habitats in the Southern Ocean surrounding Antarctica are crucial during all stages of the species annual cycle. Changes in wind, temperature, and associated sea ice patterns in some of the more northern regions of the species range in are causing reductions in the size and distribution of Adélie penguin breeding colonies.
