In 1939 J.E Hamilton published his second report on Falklands’ southern sea lions. His reports are part of the Discovery Reports – the culmination of seminal multi-disciplinary research that involved a series of Antarctic cruises and land-based surveys between 1925 - 1951. Hamilton’s report contained a short note on the winter migration of southern sea lions. The note was based on his observations of the Cape Dolphin colony between 1935 – 1937. In summary, Hamilton suggested part of the Falkland Islands population may migrate away from the Islands during winter. His idea stuck. A quick internet search on southern sea lions reveals statements such as ‘the Falkland Islands are largely abandoned during the winter’, undoubtedly in reference to Hamilton’s salient work. However, while some females move to different haul out sites with their pups over winter and males disperse from breeding beaches, do sea lions really leave the Falklands entirely? A glance at Sealing on the Falkland Islands by local author J.R. Allen suggests that at least some sub-adult and adult males actually remain at the Falklands year round. A fact that I am sure many local land owners would also attest to.
