Feathers are the things which cover birds. They help keep birds warm. Feathers also protect them from injury. In most kinds of birds, wing feathers help them to fly. These are called flight feathers. Some people have their pet birds clipped. This is a procedure where a vet or a groomer cuts a certain amount of feathers to prevent the bird from flying away or simply for medical reasons. [1]
