Shedding one's feathers is a process known as molting. Molting is the natural process of shedding old feathers and replacing them with new ones. This process is necessary for birds to maintain their health and keep their feathers in good condition. Molting usually occurs once or twice a year, depending on the species of bird. During this time, the bird will lose its feathers and grow new ones. The new feathers are usually brighter and more vibrant than the old ones. Molting is an important part of a bird's life cycle and helps them stay healthy and strong.
