It was named "Megalestris" after an obsolete generic name for the south polar skua, which are found on the island. A cairn with a lead plaque was erected on the hill in 1909. The original plaque has since been removed to the Museum National d’Histoire Naturelle in Paris, but the cairn, with a replica plaque, has been designated a Historic Site or Monument (HSM 27), following a proposal by Argentina, France and the United Kingdom to the Antarctic Treaty Consultative Meeting. The island has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a breeding colony of about 3,000 pairs of gentoo penguins. Other birds nesting at the site in smaller numbers include Adélie penguins, imperial shags, Wilson's storm petrels and south polar skuas. Groussac Refuge () is an Argentine naval refuge (originally called Hippolyte Bouchard) in Antarctica, located on the southern coast of the Port Circumcision, on Petermann Island, next to the west coast of the Antarctic Peninsula. The refuge was inaugurated on February 6, 1955 and is operated by the Argentine Navy and was occupied periodically by personnel of the British Antarctic Survey of the former Faraday Station. The refuge take place in the middle of a colony of Gentoo penguin. Its current name is in honour of Paul Groussac, a French writer and historian who lived in Argentina, author of a plea on the Argentine claim of the Malvinas Islands and biographies of Argentine national heroes.
