Analysis of sedimentary ancient DNA has illuminated 6,000 years of the lives of Adélie penguin colonies on Antarctica's Ross Sea coast, showing how animals in the region responded to climate and ...

The eating habits of Adélie penguins in Antarctica changed significantly about 200 years ago, according to chemical analyses of the birds’ eggshells. Scientists attribute the shift in diet to ...

To ensure their color-based interpretation of the penguins’ diet was correct, the researchers compared Landsat images to chemically analyzed samples of guano collected on the ground.

A study on a Victorian penguin colony has revealed new insight into the link between seabird diet and breeding success.

The king penguin diet is high in nitrogen. What goes in one end comes out the other. Once on the ground, soil bacteria goes to work turning the nitrogen into laughing gas.

The gentoo penguin’s ability to adapt its diet to modern changes in food availability is likely behind the gentoo’s recent population increases.

Images from the satellite archive indicates that the penguins haven’t changed their diet over time. You can find out more about Antarctica’s penguins, and also become a “penguin detective” at ...

Newly revealed fossils of four new ancient penguin species highlight how their early evolution optimised wings and feet for ...

Around 200 years ago, a group of Antarctic penguins switched from eating mostly big fish to a diet of tiny crustaceans. And new research suggests humans might have forced the change. The ...
