World's largest penguin colony down 63% since 2011, climate-driven food stress cited

A study reports a 63% decline in nests at the world's largest penguin colony between 2011 and 2025, attributing the loss to climate change affecting food supply and bird survival. The finding is based on nest counts, but the causal link to climate is inferred rather than directly proven. This signals a significant ecological impact in the Antarctic region, with implications for biodiversity and climate policy.
