It looks plump. Are they usually that big?

When it's cold, birds puff up their under downy feathers to create air pockets, which help them keep warm. The soft, fluffy feathers act like a down jacket with air to create a warm blanket around the bird. Their top body feathers lie on top of the down, overlapping like shingles on a roof. Small interlocking barbules, or “hooks,” zip their feathers together to create an airtight windbreaker. He may look fat but he's really just very, very cold.

Thanks for the comment, Sarah
