Antarctic penguins have radically shifted their breeding season – seemingly in response to climate change | Antarctica | The Guardian

Antarctic penguins have shifted their breeding season significantly, likely in response to climate change, according to a decade-long study by PenguinWatch at the University of Oxford and Oxford Brookes University. The study, published in the Journal of Animal Ecology, found that Adélie, chinstrap, and gentoo penguins have advanced their breeding by up to 24 days. This shift threatens their survival as it could lead to a lack of food for chicks and increased competition for resources.
