☆ Chinstrap penguins take thousands of 4-second naps a day so they can stay alert and guard their newborns around-the-clock, researchers say

Chinstrap penguins take catnaps instead sleeping for a long period of time, researchers found. Chinstrap penguins in Antarctica need to guard their eggs and chicks around-the-clock in crowded, noisy colonies. Chinstrap penguins, named for the thin line of black facial feathers resembling a chinstrap, usually lay their eggs in pebble nests in November. For the first time, the scientists tracked the sleeping behavior of chinstrap penguins in an Antarctic breeding colony by attaching sensors that measure brain waves. "For these penguins, microsleeps have some restorative functions — if not, they could not endure," he said.

☆ Extreme sleep behavior documented in cute Antarctic chinstrap penguins

Guarding their nests is serious business for these medium-sized penguins, with predatory seabirds called brown skuas on the prowl. But this species, scientists said on Thursday, has devised an ingenious way of getting sufficient sleep without compromising vigilance. The researchers documented extreme sleep behavior in these flightless birds. "Penguins do not display any obvious negative consequence of sleep fragmentation," Libourel said. During incubation, skuas prey on penguin eggs, particularly on a colony's periphery.

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. These short “microsleeps,” totaling around 11 hours per day, appear to be enough to keep the parents going for weeks. “For these penguins, microsleeps have some restorative functions — if not, they could not endure,” he said.
