Wing shapes are crucial for the flight performance of birds and aircraft. Different shapes, such as elliptical, delta, and straight, affect how well a wing can generate lift and maneuver. For instance, elliptical wings are efficient for gliding, while delta wings are often used in high-speed aircraft due to their stability at high angles of attack. The design of a wing also influences its speed and agility. Long, narrow wings are typically found on birds that soar, allowing them to cover large distances with minimal energy. In contrast, short, broad wings provide better control and are common in birds that need to navigate through dense environments.
