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.

The investment in microsleeps by successfully breeding penguins suggests that the benefits of sleep can accrue incrementally.

(via This penguin survives on 4-second microsleeps — thousands of times a day)

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.

In humans, nodding off for a few seconds is a clear sign of insufficient sleep – and can be dangerous in some situations, such as when driving a car. ​But a new study published on Thursday finds chinstrap penguins snooze thousands of times per day, accumulating their daily sleep requirement of more than 11 hours in short bursts averaging just four seconds. ​The flightless birds might have evolved this trait because of their need to remain constantly vigilant, according to the authors of the paper in Science. ​The researchers argued that the findings show, contrary to prior assumptions, the benefits of sleep can accrue incrementally, at least in some species. Chinstrap penguins (Pygoscelis antarcticus), named for the thin black band of plumage that extends from ear to ear, may be the most abundant species of penguin.

Dormir 10 000 fois par jour

Il existe une espèce de manchot, en Antarctique, qui fait plus de 10 000 siestes par jour… mais de quelques secondes chacune. Des « microsiestes » sont courantes dans le monde aviaire. On connaît plusieurs espèces d’oiseaux qui « sommeillent » pendant une dizaine de secondes, à raison de centaines de fois par jour. Le manchot à jugulaire (Pygoscelis antarcticus) vient toutefois de battre tous les…

If penguins disappear in Antarctica, the ecosystem is at risk, also for iron

The Antarctic pigeon pigeon (Pygoscelis antarcticus) is a penguin and not doing well, not at all. Compared to forty years ago its populations have decreased by 50%. And if this is already bad news, it is not the only one: if this penguin disappears, the entire iron cycle of the Southern Ocean is also at risk, because penguins, like whales, eat the krillrich in iron, and re-pass it in the feces.…
