Chinstrap penguins (Pygoscelis antarcticus) nod off more than 10,000 times a day for an average of 4 seconds at a time, researchers have found. The short snoozes, which add up to more than 11 hours of daily sleep, seem to be enough to fulfil at least some of the restorative functions of sleep, according to a study published today in Science1.

Pairs of chinstrap penguins, their bellies muddy from scrambling over ice-free spots where they build their nests, point their bills skyward and emit a honking call, perhaps to signal: “This is my patch.” Neighbors join in with a noisy chorus that ripples in waves across the colony. Chinstrap numbers along the peninsula appear to be declining, a sign that the Southern Ocean ecosystem is changing drastically, possibly because of a combination of climate change and commercial fishing for krill, a penguin staple.

Day 10. The land of 8,000 penguins.
Today was the final day of expeditions on our Antarctica adventure and nature pulled out all the stops for us. Come see for yourself.

Antarctica Day 4
What a fucking day then! They’d told us yesterday if conditions were good, which was 50/50, that we could land on one of the South Shetland Islands. We tried to keep our hopes in check but it’s difficult, especially when we got our first glimpse of land, plus a bonus iceberg for good measure. It was all pretty exciting and the water was as calm as it could be.
This albatross looks like it’s on a…

ANTARTIC PENGUINS CHAMPIONS OF POWER NAPS
Microsleep in humans are dangerous when driving, but just now, researchers found out penguins dominated microsleep, using these short sleep periods as strategy to balance sleep and vigilance requirements. An international team of researchers at the King George Island were looking at breeding chinstrap penguins (Pygoscelis antarcticus) using remote electroencephalogram monitoring, to they found out penguins nodded off more than 10,000 times a day, for only around 4 seconds at a time, but penguins still managed to accumulate close to 11 hours of sleep.
The brown skua (Stercorarius antarcticus), are very smart birds, and one of the main predators in nesting colonies. During incubation, skuas are known to prey on penguin eggs mainly on the border of the colony. As one penguin parent must therefore guard the eggs or small chicks continuously while its partner is away on foraging trips lasting several days, they face the challenge of needing to sleep while protecting their offspring In addition, they also have to effectively defend their nest site from intruding penguins, they need to stay alert.
-Recordings showing typical microsleep episodes in chinstrap penguins.
The investment in microsleeps by successfully breeding penguins suggests that the benefits of sleep can accrue incrementally.
Reference (Open Access): Libourel et al. 2023. Nesting chinstrap penguins accrue large quantities of sleep through seconds-long microsleeps. Science
