Four species of penguins were found on Ardley Island of King George Ishnd during the austral summer of 1993 and 1994. Macaroni Penguin Eudyptes chrysolophus is a new record of bird on this Island, The numbers of nests found were 44 1205 and 3678 for Chinstrap Penguin Pygoscelis antarctica, Adelie Penguin P. adeliae and Gentoo Penguin P. papua respectively. Totally about 7430 fledged penguin chicks were produced on Ardley Island in the summer of 1993 and 1994. The decrease of the Island population of Chinstrap Penguins might have resulted from the increasing human disturbance.
