Molting is also known as shedding, signifies the manner in which an animal routinely casts off a part of its body (often but not always an outer layer or covering either at specific times of year, or at specific points in its life-cycle. Moulting can involve the skin, hair or fur, or other external layer. Ducks shed their feathers and grow new ones twice every year first moult is in early summers and the process takes few weeks. During the first part of the molt, a duck's body feathers fall out. New feathers grow in, and they're dull brown and a bit scraggly. The feathers don't look flashy, but blend in with the landscape instead. This is important, because the wing feathers are about to fall out. For the next three to four weeks, ducks will not be able to fly. So they hide themselves in grass or somewhere else. As new wing feathers grow, they're filled with blood and are actually heavy. They grow fast. In one day, a wing feather may grow about the length of your pinkie nail, or even more! Once feathers stop growing, blood no longer flows to them. They become hollow and light. September is followed by second moulting.

When an animal sheds its skin or feathers and replaces it, we call that "moulting". Amphibians, reptiles, birds, and even insects moult.
Birds grow a whole series of feathers during their lifetime. When
they reach the adult Stage' they have the plumage that is typical of their kind of bird. Then adult birds change this plumage from time to time as old worn feathers moult (drop out) and new ones grow in their place.
If a feather is pulled out, it begins to replace itself at once. In addition, some birds grow bright, new feathers for the breeding season by moulting. So most birds moult twice a year, once before and once after the breeding season.
Since most birds do not shed many of their flight feathers at the same time, they are able to fly all through the moulting period. Also, flight feathers are often shed in pairs, one from the right and one from the left wing, so the flying balance is not upset. Ducks, swans, and geese are exceptions to this. They lose all their flight feathers when they moult, so they cannot fly. But since they are water birds they do not have to fly to escape from danger. They just take to the water.
During the moulting season the brightly colored males often take on a drab-coloured set of feathers. This gives them the added protection of camouflage and makes it easier for them to hide.
Snakes have an interesting way of shedding their skin. A snake does not shed its entire skin, just the thin outermost part. The snake rubs its snout against something rough to loosen the old skin around the lips. Next it manages to get the loose parts caught on a rock or twig. Then the snake crawls out through the mouth opening of the old skin. It leaves the old skin in a single piece and wrong side out.
