Birds have wings that are specially adapted for flight. These wings are made up of feathers, which provide lift and help with steering. The structure of a bird's wing includes bones similar to those in a human arm, allowing for movement and flexibility. Different species have varying wing shapes, which can affect their flying abilities. The size and shape of a bird's wings are influenced by its habitat and lifestyle. For example, eagles have large, broad wings for soaring, while hummingbirds have short, rapid wings for hovering. This diversity in wing design helps birds thrive in their environments.
