Waterfowl - Free stock photo

It is a stock photo of the waterfowl that doesn’t float on the water as it is cold and is. Is this a duck?The bird rounds the neck and the face has been buried under my body though an accurate thing is not understood well. Do you sleep?The head was occasionally put out and it visited around. It is pure-white. It might not be a duck because it thinks that the duck doesn’t image such a color somehow. Some kinds of birds arrive unexpectedly at the city though it is a bird that is floating in the river in the city. Why are you in such a river though are seems to in such a place wonderful food either?However, do you fly away anywhere at once only by resting wings?
