Birds need feathers and wings to fly but unfortunately all birds cannot fly. Birds with hollow bones can fly because this feature makes it lightweight and helps it to fly.
Peacock is a beautiful bird that has a distinctive blue color. The feathers also known as plumage cover 60% of body size. Due to its long size feathers, peacocks cannot fly longer distances, however they can cover short distances.
