Why does huddling keep penguins warm

So if the penguins for some reason began to huddle at warmer temperatures, scientists would know that they likely had smaller energy reserves from food to keep them warm. The findings agree with the well-established idea that the penguins huddle primarily for warmth and not for protection against predators and reconcile lingering questions about the main environmental trigger for huddling.

Cartier, K. Published on 13 June For this timing to work, emperors gather in large groups on sea ice to begin their breeding in April, lay their eggs in May, and then the males protect the eggs for four months throughout the harsh Antarctic winter.

These temperatures could easily kill a human in minutes. But emperor penguins endure it, to give their chicks the best start in life. 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.

This is another adaptation to keep them warm. The first place that you feel cold is your hands and feet, because these parts are furthest from your main body and so lose heat easily. This is the same for penguins, so they have evolved a small beak , small flippers, and small legs and feet, so that less heat can be lost from these areas.

They also have specially arranged veins and arteries in these body parts, which helps recycle their body warmth. For example, in their nasal passages inside their noses , blood vessels are arranged so they can regain most of the heat that would be lost by breathing.
