Of 62 known penguin colonies, around 30% were harmed by low sea-ice levels last year — and 13 likely failed entirely, Fretwell said. “That this could happen doesn’t shock me, but I’m ...

That year, seasonal sea ice broke up before penguin chicks had time to develop waterproof adult feathers and about 10,000 baby birds drowned, Jenouvrier said. The colony did not recover afterward.

A new study argues emperor penguins should be classified as an endangered species because of shrinking ice. NPR's Linda Wertheimer speaks with scientist Hal Caswell, who co-authored the study.

A three-century record of penguin poop shows that the flightless birds probably thrived during the Little Ice Age, a Chinese research team says.
