The center of a penguin huddle, a form of social thermoregulation, can reach temperatures of up to 37° Celsius (98.6° Fahrenheit). It’s so warm that the center penguins keep moving through the huddle so that they don’t overheat, while penguins on the outside move inward to get warm.Massive huddles of male Emperor penguins are crucial to keep them warm during Antarctica’s brutal winter while they incubate their eggs. The trick with these groups is to get the packing just right. If too loose, they won’t stay warm.In studying the video recordings they made, they discovered that huddling typically only lasted on average from twelve minutes to a few hours, and the average length of time an individual penguin spent in a huddle was just 50 minutes.

On the frozen landscape of Antarctica, emperor penguins huddle together to shield against cold, windy, and harsh conditions. This lets the penguins share warmth and conserve energy during extended times between forages and during breeding.
What happens when penguins are not in a huddle?
Birds within a colony crowd together so tightly that individual movements are impossible. Collective movements are a must, however: The penguins on the periphery would die of cold if they weren’t continuously being reshuffled toward the center of the crowd.
How many emperor penguins can be found in a huddle?
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.

Emperor penguins have four layers of overlapping feathers that provide excellent protection from wind, and thick layers of fat that trap heat inside the body. Have you ever noticed that an emperor penguin’s body looks too big for its head and feet? This is another adaptation to keep them warm.
Does huddling for warmth work?
Heat flows from a hotter object to a colder object in several different ways. For example, when puppies are huddling together to keep warm, they are reducing how much of their bodies (specifically surface area) are exposed to the colder open air, and so are reducing heat loss in two ways: via radiation and convection.
