Giant iceberg threatens penguins : A grounded iceberg near one of Antarctica's largest emperor penguin colonies was later linked to a devastating breeding season for the birds.
Researchers found that the number of surviving emperor penguin chicks on Coulman Island dropped by 69% in 2025 compared with the previous year. Their study, published in 'Communications Earth & Environment', suggests the grounded iceberg disrupted the adults' journey back from the sea, delaying food deliveries to their chicks.
