Investigator Group Expedition 2006: Vertebrate Fauna

AbstractThe vertebrate fauna of the Investigator Group includes 11 native (five now extinct) and four introduced mammals, 63 native and four introduced birds and 20 native reptiles. The determination of the total mammal fauna of Flinders Island was based on sub-fossil bone collections. The extinction of the Flinders Island form of the Tammar Wallaby between 1968 and 1974 is described. Australian Sea-lion and New Zealand Fur-seal breeding colonies and haul out sites on all the islands are documented. Sea-lion pup numbers on Ward Island greatly exceeded any previous reports.
