Inter-annual variability in Chinstrap penguin diet at South Shetland and South Orkneys Islands

Inter-annual variability in the diet of Chinstrap penguins (Pygoscelis antarctica) at Laurie Island (South Orkney Islands) and 25 de Mayo/King George and Nelson Islands (South Shetland) was examined based on stomach contents of adults during the 2002/2003-2006/2007 and 2002/2003-2004/2005 breeding s...
