Birds fly in the air for many hours whereas humans cannot. They have the ability to escape from the gravity of the planet into the clouds Different birds have different flying speeds. Some birds fly very high in the air. The main difference is in their body mechanics. Birds fascinate us in many ways from their colorful feathers and complex songs to their impressive displays of courtship and diverse diets. Here’s everything you need to know about how birds fly in the air.
The physics of birds flight
There are many factors that contribute to the birds’ flight. Physical characteristics, behavior, and local air conditions all help define how birds fly.
How birds fly with wings?
Birds fly with wings due to their unique shape and motion. Flying in the air is an art that’s why its not possible for humans to fly without any assistance.
Wing Shape– Birds fly with the aid of wings and the bird’s wing thickness differs among different birds. But, normally in all bird’s thickness and the curvature of the wing is different at the front and back. The wing of a bird is thicker at the front than at the back, and more curved across at the top than underneath. As a result, air moves faster over the upper wing long surface than underneath under the wings shorter surface. Due to the difference in airspeed above and below the wing causes lower air pressure is induced on top and stronger pressure below, which is the lift that raises the wing and propels the bird higher.
In contrast to birds, human beings have arms that’s why humans couldn’t fly. Human arms could not generate force like bird’s wings. In addition, the shape of human arms is structurally different from wings that’s why humans could not fly.
Wing Motion– As a bird flaps, the wing bends slightly to take advantage of wing shape and produce more thrust to propel the bird forward and up into the air. This pushes the bird through the air, similar to how a swimmer will push through the water with every stroke as they change the position of their shoulders, hands, and arms. body help out in flying
Role of body in birds flight
Body Structure– The body structure of a bird assists the bird to fly. Bird skeletons are a lattice-like structure or honeycomb shape filled with air hollows, which decreases the bird’s overall weight. Fewer redundant organs, such as a single ovary instead of a pair, reduce the weight of a bird to make it easier to fly. Larger muscles in the chest give more power for better flight to a bird’s wings.
Whereas, human’s body shape is totally different from birds. The difference in skeleton and muscle work didn’t allow humans to fly like birds.
Body Activities– Bird’s body is designed in a way that helps the bird to fly. The internal workings of a bird’s body also help it fly more efficiently. The body temperature of a bird should be higher to allow the muscles to work faster. Both the circulatory and respiratory systems are operating more efficiently to support the massive effort needed to fly. The circulatory system provides massive blood to the muscle during flight Muscle demands increases with an increase in the working of muscles. The respiratory system also provides oxygen to muscles via blood in our circulatory system. Birds also have higher metabolic rates so they can digest food more quickly to turn it into energy for the flight. Therefore, birds digest food faster to convert it into flight fuel.
Feathers– The feathers of a bird are more than just a bright body cover. A growing feather is aerodynamically designed and placed precisely to aid flight by changing the airflow over and around the wings and body of the bird. Many key feathers can be modified by birds to help steer through the air, and tail feathers are often used as a rudder for large movements
Airplanes, jets, and drones are designed by following the body features of a bird. Because this design makes flight easier by reducing friction in the air.
Streamlined Shape– Birds fly with the help of their streamlined body shapes that makes flight easier by reducing friction in the air. The tapered point of birds bill slices through the air, and the smooth curves of the bird’s body guide the air around their bulk with as little resistance as possible. Birds even tuck their legs and feet up while flying to reduce drag even further. Nowadays spaceships and airplanes are designed
Leg Power– Birds fly by using their powerful legs to assist their flight. Legs provide initial thrust needed to get into the air. For many birds, this is from a first leap as the bird jumps into flight. Similarly, many waterfowl use their strong legs and webbed feet to build up speed across the surface of the water as they take off into flight
How Air Condition affects the bird’s flight?
Birds fly in different air conditions and air also influences greatly during flight. Not only are birds spectacularly equipped to be efficient fliers, but they also take advantage of air conditions to make the flight more efficient. Differences in air, wind and air temperature all contribute to the dynamics of flight and help birds fly. To detect air temperature birds use their sensitive skin. Skin can detect slight changes in the atmosphere. Birds adjust their flight behavior according to temperature to make it easier to fly under different air conditions.
Hence, in order to fly like birds humans should have wings and unique body shapes. Because air condition relies heavily on body features that assist during flight.
