Summary
Regurgitated boluses of undigested material were examined from six sites in East Antarctica. Skuas nesting near Adelie penguin, southern fulmar and Antarctic petrel colonies showed greater site fidelity in their feeding than did skuas nesting close to cape petrels or a Weddell seal pupping site.
