Analyzing Ducks

Ducks are made up of many parts, and many systems, much like all other animals. They have a nervous system, a respiratory system, an endocrine system, and a digestive system. Ducks are birds, so they have wings, and they can fly. They have webbed feet, which are better for propelling themselves while they swim in water. Their feathers are very water resistant, which is what helps them float on top of the water. They also have a rounded bill, rather than the beak that some birds have. When ducks mature, they loose their baby feathers, called down feathers, which are used in clothing, and blankets and such. Ducks lay eggs.
