Bird life

Birds are a type of poultry. Birds have the same characteristics as other poultry animals. the characteristics of birds are the surface of the skin covered with feathers, has a beak, has a pair of legs, and a pair of wings. Some types of birds can fly using their wings. In the bird's wing bone there is a cavity that makes it easier for it to fly. when flying, the bird uses its wing muscles to flap its wings. These muscles are the driving force to be able to fly into the sky. There are several types of birds that cannot fly, for example, ostriches and penguins. Both types of birds do not use their wings to fly. Ostriches use their legs more often to run when in danger, while penguins use their legs to help them swim and dive underwater when looking for food
