Emperor penguins have to face freezing conditions including katabatic winds that blow off the polar plateau and intensify the cold. To keep warm, the males close ranks to share their warmth. When carrying their incubation fat, emperors are about as large around the chest as an average man. On very cold days, as many as 10 of them pack into every square metre of a huddle. In the huddle, individuals seem to temporarily lose their identity, and the group takes on the appearance and behaviour of a single living entity.

The warmer they are, the longer their fat lasts. On a social level, huddling behaviour is an extraordinary act of co-operation in the face of common hardship. Emperors take this to an extreme taking turns to occupy the warmest and coldest positions in the huddle.

On windy days, those on the windward edge feel the cold more than those in the centre and down-wind. One by one they peel off the mob and shuffle, egg on feet, down the flanks of the huddle to join it again on the leeward side.

They follow one another in a continuous procession, passing through the warm centre of the huddle and eventually returning back to the windward edge. Due to this constant circulation, the huddle gradually moves downwind. During a hour blizzard, the huddle may shift as much as metres.

Why live in Antarctica? Chicks hatch after about two months. At this point, chicks are without defense against the Antarctic environment and rely entirely on their parents for warmth and food. If emperor females have not returned from feeding yet, males feed their chicks with a substance they cough up from their esophagus. Female emperor penguins return somewhere around the beginning of August, locating their families by familiar calls made by their male partners.

Females then take over feeding the chicks and keeping them warm, and now it is the males that head to sea to feed. They remain at sea for just shy of a month. The trek back to sea begins in December, at which point the breeding cycle starts all over again. A survey of satellite images from found 46 colonies containing , breeding pairs, suggesting a total of , individual emperor penguins. Since then, a further seven colonies have been discovered.

Emperor penguin chicks are preyed upon by other birds like southern giant petrels and south polar skua, while orcas and leopard seals are known to feed on adult emperor penguins.
