| Abstract | Describes beak deformation in Antarctic cormorant chick at Nelson Island, South Shetland Islands during 2000-01 breeding season. Despite normal feeding behaviour, increase in mass was slow, and reached peak of 1780 g at 38 days, roughly 59% of usual body mass of fledging chicks. Normal chicks were permanently brooded up to 20 days, but deformed chick was brooded up to age of 42 days, and died at 44 days just after starting to moult. |
