When you see a bird puffing up its feathers, it’s usually doing so to stay warm. By trapping air between its feathers, the bird creates an insulating layer that helps keep its body temperature stable, especially in cold weather.
Puffing up can also be a sign of contentment or part of a mating display. It’s one of the many clever ways birds adapt to their environment.
