摘要

Adelie penguins, Pygoscelis adeliae, breed around much of the Coast of Antarctica, but the lack of ice-free areas close to the coast prevents breeding between the Antarctic Peninsula (57° W) and around Syowa Station (39° E). The only place where they have been recorded attempting to breed along this 4000 km stretch of coastline is at the Schirmacher Oasis (12° E). However, this site is 80 km inland from the ice shelf edge, and only a few isolated breeding attempts have been recorded; no colonies have been observed. We report a colony of some 60 pairs on a small rocky outcrop at the northern extreme of Schirmacher Oasis in 2024/2025. At least 12 pairs laid eggs and most hatched chicks, some of which survived for at least one week. However, no chicks survived to fledge, presumably because the very long commute to the sea prevented adults from delivering sufficient prey to their chicks. Our observations indicate that Adelie penguins will attempt to breed in the absence of suitable sites close to the coast.
