Why do birds puff their feathers in winter?

Answered by admin @ 17/08/2021

Feathers are a good insulating material. By fluffing its feathers, a bird traps many tiny pockets of air to hold in body heat and keep out the cold....When the weather is hot, the bird presses its feathers close to its body to eliminate the insulating air pockets so that body heat is allowed to escape...The insulating quality of feathers is a drawback when the bird is trying to incubate its eggs. The feathers keep some of the body heat from reaching the eggs. To overcome this problem, the bird either sheds some of its breast feathers naturally or pulls them out to expose the bare skin. This bare area is called the brood patch, and egg temperatures next to it may be as much as six degrees higher than those next to the feathers.
