Diet of post-breeding Antarctic Shags Phalacrocorax bransfieldensis at Cockburn Island, Antarctic Peninsula

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, followed by invertebrates. Among the...

Demersal-benthic fish were the most frequent and important prey, followed by invertebrates.
