Although huddling was shown to be the key by which emperor penguins (Aptenodytes forsteri) save energy and sustain their breeding fast … during the Antarctic winter, the intricacies of this social behavior have been poorly studied.
In 1956, an emperor penguin (Aptenodytes forsteri)colony had been reported during an aerial survey north of the north-western protrusion of the West Ice Shelf in East Antarctica. About 15,000 birds were estimated to be present.
For Emperor penguins (Aptenodytes forsteri), huddling is the key to survival during the Antarctic winter. Penguins in a … huddle are packed so tightly that individual movements become impossible, reminiscent of a jamming transition in … compacted colloids. It is crucial, however…
This article summarises the history of the discovery of emperor penguin Aptenodytes forsteri colonies. Emperor penguins were probably first seen on James Cook’s second voyage (1773–1775) but were not recorded as a … separate species until 1844.

Penguins breeding in the Antarctic have evolved in the most isolated ecosystem in the world. However, recent increase in human activity in the region, both in tourism and science, has led to concern regarding the possible introduction of infectious agents to Antarctic wildlife.
Penguins breeding in the Antarctic have evolved in the most isolated ecosystem in the world, receiving only very minimal exposure to infectious agents from other regions. However, yearly expansion of human activity in the region, seen both in tourism and science…
