A birds tail swerves its body left and right. It also has drag.
Weight and lift are two forces that affect a bird's flight. Two other forces are drag and thrust.
Wings and feathers
Birds use the four forces of flight (lift, weight, thrust, and drag) by flapping their wings to generate lift and thrust. They adjust the shape and angle of their wings to control lift and maneuverability, while altering their body position and speed to manage drag and weight. By combining these forces effectively, birds can achieve sustained flight for various purposes such as foraging, migration, and predator evasion.
Flightless birds do not need a large keel because they don't have functional wings for flight, so there is no need for the large breastbone attachment needed for flight muscles. The keel is an adaptation found in birds that use their wings for sustained flight.
Birds reduce drag by streamlining their bodies and wings to minimize air resistance. They also adjust their wing shapes and positions during flight to further decrease drag. Some birds fly in formation to take advantage of the reduced drag created by flying behind another bird.
what is the significant of birds first flight
Yes, you can take birds on an international flight, but there are specific regulations and requirements that need to be followed. It is important to check with the airline and the destination country's regulations regarding the transportation of birds before planning your trip.
drag
The drag is caused by friction with the air or water.
Aircraft need a force from their engines to counteract the drag force that acts against them as they move through the air. This force is necessary to maintain a steady speed and keep the aircraft in level flight.
Birds are groups of animals equipped for flight.
