Elephant bird process of continental drift. Claims of findings of "aepyornithid" egg remains on the eastern Canary Islands, if valid, would represent a major biogeographical enigma. These islands are not thought to have been connected to mainland Africa when elephant birds were alive. There is no indication that elephant birds evolved outside Madagascar, and today, the Canary Island eggshells are considered to belong to extinct North African birds that may not have been ratites (possibly "Eremopezus"/"Psammornis", or even Pelagornithidae, prehistoric seabirds of immense size). Various "aepyornithid-like" eggs and bones occur in Paleogene and Miocene deposits in Africa and Europe. Two whole eggs
Bird Island, South Georgia wandering albatross were ringed, which gave startling data about their range - one bird was found in Australia . The island is currently a Site of Special Scientific Interest, and so there are no landings allowed without permission. The summit of the island, Roché Peak is named after the Englishman Anthony de la Roché who discovered South Georgia in 1675. 2008 marked the 50th anniversary of biological research on Bird Island. The island has been a station for Antarctic research since 1963, and is currently a biological research station of the British Antarctic Survey (BAS) at Jordan Cove, with three
