Adélie penguin
The group contains breeding colonies of Adélie penguins, Cape petrels, snow petrels, southern giant petrels (which breed nowhere else in the region), Wilson's storm petrels and Antarctic skuas. The islands are protected under the Antarctic Treaty System as Antarctic Specially Protected Area (ASPA) No.102. The 89 ha site has also been designated an Important Bird Area (IBA) by BirdLife International, principally because of the Adélie Penguin colony.
