While incubating their eggs, chinstrap penguins need to stay vigilant for predators – so they only sleep for a few seconds at a time

WASHINGTON (AP) — It’s a challenge for all new parents: Getting enough sleep while keeping a close eye on their newborns. For some penguins, it means thousands of mini-catnaps a day, researchers discovered. Chinstrap penguins in Antarctica need to guard their eggs and chicks around-the-clock in crowded, noisy colonies. So they nod off thousands of […]

For some penguins, it means thousands of mini-catnaps a day, researchers discovered. Chinstrap penguins in Antarctica need to guard their eggs and chicks around-the-clock in crowded, noisy colonies. “These penguins look like drowsy drivers, blinking their eyes open and shut, and they do it 24/7 for several weeks at a time,” said Niels Rattenborg, a sleep researcher at the Max Planck Institute for Biological Intelligence in Germany and co-author of the new study.
