Why don’t birds get cold in the wind?
Birds have insulating feathers called *down*. They trap air close to the body so convection (moving air currents) can't pull heat away. To get their feathers to do this, their muscles can make the feathers stand on end — these are *literally* goose bumps.
The Short Answer
Birds have insulating feathers called *down*. They trap air close to the body so convection (moving air currents) can't pull heat away. To get their feathers to do this, their muscles can make the feathers stand on end — these are *literally* goose bumps. By the time it gets warm, they have shed many of their insulating feathers due to molting, and what remains is kept tight against the skin, allowing for maximum cooling.
