How an iceberg may have stopped emperor penguins from breeding on Coulman Island in 2025
The number of chicks in the Coulman Island emperor penguin colony decreased by about 69% in 2025 compared with 2024, according to research published in Communications Earth & Environment. The authors suggest that a large iceberg, which grounded off the island between July 2025 and January 2026, likely restricted the colony's access to important foraging areas, demonstrating that individual iceberg movements may affect breeding success even when …
(Seoul=Yonhap News) Reporter Lee Joo-young = A massive iceberg stranded in the waters off an emperor penguin breeding ground in the Ross Sea sea ice in Antarctica is blocking the path penguins take to and from their sea hunting grounds...
A tragedy occurred in Antarctica where a massive iceberg blocked the migration route of emperor penguins, causing approximately 7 out of 10 chicks to starve to death. This was because the mothers, who had gone to find food, were unable to return to their nests in time. This incident is interpreted as proof that even if the sea ice serving as the emperor penguin habitat remains intact, their survival can be threatened if an iceberg detached from …
