Emperor Penguins

View full context
The flightless emperor penguin is capable of becoming airborne, by swimming at up to three times its normal speed, and launching itself from the water to clear the edge of a shoreline. Recent research shows that the penguins do this by releasing air from their feathers, in the form of tiny bubbles.

Emperor Penguins

18 November 2011

Ross Sea, Antarctica 

Swimming emperor penguins shoot to the water’s surface. The cloud of bubbles they create may help confuse predators.

 

Emperor penguins’ body shape and poor climbing ability make it difficult for the birds to haul themselves ashore, especially onto icy or rocky coasts. It is also a moment when they are especially vulnerable to attacks by predators, such as the leopard seal.

But the flightless emperor penguin is capable of becoming airborne, by swimming at up to three times its normal speed, and launching itself from the water to clear the edge of a shoreline. Recent research shows that the penguins do this by releasing air from their feathers, in the form of tiny bubbles. The bubbles act as a lubricant, cutting drag, and enabling the birds to achieve bursts of speeds that would otherwise be impossible.

Des manchots empereurs regagnent la surface, dans la Mer de Ross, en Antarctique.

Le corps du manchot empereur et ses piètres capacités de grimpeur ne lui permettent pas de se hisser facilement hors de l’eau, surtout sur des côtes glacées ou rocheuses. C’est aussi le moment où il est le plus vulnérable aux attaques de prédateurs. Mais le manchot empereur, qui ne vole pas, arrive à se propulser hors de l’eau sur le littoral en triplant sa vitesse de natation.

Le manchot libère pour cela de l’air de ses plumes sous la forme de minuscules bulles qui agissent comme un lubrifiant, diminuant ainsi la résistance et permettant à l’oiseau de réaliser des pointes de vitesse autrement impossible à atteindre.
