The wing structure of birds and insects is designed for flight, featuring a combination of strength and flexibility. In birds, wings are made up of feathers, bones, and muscles, allowing them to generate lift and maneuver in the air. The shape of the wing, known as the airfoil, helps create differences in air pressure, which is essential for flying. Insects, on the other hand, have a different wing structure. Their wings are often thin and membranous, supported by a network of veins. This design allows for rapid flapping and agile movements. The unique wing structures of both birds and insects showcase the incredible adaptations for flight in nature.
