Fortunately birds have many adaptations to stay warm in the winter. When fluffed up, feathers act as a buffer from the winds and wet; think downy coat. Then there is a gland at the base of most bird species tails that produces a special oil. When a bird preens they spread this on their feathers with their bill to help them become weather proof and shed water.
Also birds’ feet are made up of mainly bone, tendon, and scaly skin. And unlike humans, birds don’t have sweat glands in their skin to produce any moisture to freeze.
