FORMERLY: Specially Protected Area (SPA) No. 3, Ardery Island and Odbert Island, Budd Coast Ardery and Odbert Islands support several breeding species of petrel and provide a sample of their habitat. There is no other readily accessible place in eastern Antarctica where the four genera of fulmarine petrels (Thalassoica antarctica, Fulmarus glacialoides, Daption capensis and Pagodroma nivea) breed in the same place in sufficient numbers to allow comparative study. Study of these four genera at the one location is of high ecological importance both from the point of view of understanding and of monitoring the Southern Ocean ecosystem. It is believed that Ardery Island is unique insofar as it is the only area in the Antarctic which harbours two different subspecies of snow petrels. Studies on morphological or ecological differences between these two subspecies are not possible anywhere else. In addition both islands have breeding populations of Wilson's storm petrels (Oceanites oceanicus) and Antarctic skuas (Catharacta maccormicki) and Odbert Island supports breeding populations of Adelie penguins (Pygoscelis adeliae).
