Resumen:
The diet of post-breeding Antarctic shags (Phalacrocorax bransfieldensis) was investigated at Cockburn Island, in the Antarctic Peninsula,through the analysis of pellets collected in February 2015. Demersal-benthic fish were the most frequent and important prey, followedby invertebrates. Among the fish, nototheniids were most abundant in the diet in terms of numbers, whereas channichthyids representedmost of the mass; Chionodraco rastrospinosus were the most frequent prey. The information provided here differs from that reported forpost-breeding individuals belonging to other shag species and for post-breeding Antarctic shags. This article discusses our results and thedifferences with previous studies, in terms of prey availability among localities.
