BY JONATHAN BRITTON. Birds make their own nest by weaving a bunch of sticks together and they use their feathers, too. Some birds make there nest upside down to keep the predators, like snakes, out. The female birds eat the baby droppings and that keeps the nest clean. Birds use feathers to fly. If the outer layer of feathers gets damaged, the birds will not be able to fly. Birds don't have arms, but they have feet that they use to cling to branches. Birds eat all kinds of things like worms, mice, rats, snakes, and some even eat dead animals. Birds feed their young by eating a worm and then they regurgitate the semi-chewed up worm into the little bird's mouth.
