Animal wings[change | change source]
Animals that have wings are insects, birds and bats. Birds' wings are made of feathers. The wings of bats are made of skin, which is stretched between the bones of the bat's arms and fingers. Not all insects and birds can fly, even if they have wings.
Artificial wings[change | change source]
- Airplanes also have wings. Those wings cannot be moved; they are stable, but the wings also produce lift, so the airplane will get off the ground if you move it fast enough.
- People also talk about wings of buildings. What they mean is usually a part of the building that is separated from the rest (for example: the west wing of a building).
