Birds are able to fly due to their unique anatomy and specific adaptations for flight. Here's an explanation of how birds fly:
1. Wings: Birds have wings that are specially designed for flight. The shape and structure of their wings generate lift, which allows them to stay airborne. The wings have a characteristic curved shape called an airfoil, with a thicker leading edge and a thinner trailing edge.
2. Feathers: Feathers are another essential feature for flight. They provide both insulation and the necessary surface area for generating lift. The outer feathers are streamlined and act like an airplane's wings, creating lift as air flows over them.
3. Hollow Bones: Birds have lightweight bones, many of which are hollow. This reduces their overall weight and allows for more efficient flight.
4. Muscles: The flight muscles of birds are incredibly powerful. The pectoral muscles, specifically, are responsible for flapping the wings with great force and speed. These muscles make up a significant portion of a bird's body weight.
5. Aerodynamics: Birds rely on the principles of aerodynamics to achieve flight. When they flap their wings downward, they generate lift by pushing against the air. As the wings move upward, they tilt slightly, reducing resistance during the upward stroke.
Now, concerning diagrams of how birds fly, you can find them on the website you mentioned: http://www.fi.edu/wright/again/wings.avkids.com/wings.avkids.com/Book/Animals/intermediate/birds-01.html. This website contains illustrations and explanations that can help you understand the mechanics of bird flight in more detail.
