Abstract
The diet of the Blue- eyed Shag, (Phalacrocorax atriceps bransfieldensis) was studied based upon remains and pelletes eyected by that species colony at Green Island, Antarctic Peninsula. This cormorant consumes preferably juvenile Notothenid fishes and Cephalopoda, minor food items were pelagic and bentho-litoral Crustaceans. The advantage and disadvantage of pellets for food habit studies, the presence of stones in those castings and the role plus trophic relations of the Blue-eyed Shag in the antarctic marine ecosystem are discussed.
