How do Birds Fly?

James embarks on a learning adventure about bird flight with Professor Birdie and Finny, an avian vet. They explore the mechanics of flight, including the roles of wings, feathers, and bones. The video covers the four forces of flight: weight, lift, drag, and thrust, and explains how different bird species utilize these forces. Various flight styles like gliding and soaring are demonstrated, highlighting the importance of wing structure and aerodynamics. The session concludes with a recap and a short quiz to test James's understanding.
