CLOSED: White Duck?

Okay we see them everywhere what are they? And what is the difference between a duck and geese?

farm ducks. People keep them as pets and sometimes they escape and take up a home on a pond.

A duck is alot smaller than most geese with a smaller neck when you see them come in ducks fly like there lifes depend on it there wings move very fast
A goose is slow and calm and take advantage of the air currents more and to me are one of the most graceful fliers its like flying is a art form
