Abstract

An evaluation of the stranding record for the period 1866 to September 2012 confirms that the Falkland (Malvinas) Islands cetacean community is composed of 7 species of baleen whale, 7 beaked whale species, sperm whale, 8 species of dolphin and 1 of porpoise. The stranding record supports the species composition based on at-sea surveys, but also confirms the presence of some rare, vessel-shy and/or offshore and deepwater species. Five species – long-finned pilot whale, Peale’s dolphin, Commerson’s dolphin, hourglass dolphin and sperm whale – are considered to have a regular presence in the Islands. Six species are considered infrequent, 11 are considered rare and 2 species had a historic presence but have not been recorded in recent years. The stranding record suggests potential temporal changes for some of these species, reflecting perhaps a recovery of their population from over-exploitation and/or changes in oceanographic conditions and/or prey availability.
