Q1 how do birds fly??
Answers
Answer:
Bird's wings have feathers and strong muscles attached to them. With the help of their strong arm and chest muscles, birds flap their wings and fly. The bodies of birds are very light which help them to fly easily. ... To stop, the bird spreads out its wings and stretches its feet.
Birds fly by flapping their wings. Flight involves moving upward, against the force of gravity, and forward too. The power for this comes when the massive chest muscles pull the wings down. ... The size and shape of the wings affect the way a bird flies.
“When a bird is flying, their wings are flat so that the air flows easily around it in the direction the animal flies (like your hand cutting through the water or air). ... So a bird wing slices in the air in the forward direction and gets pushed up from below; the net result is a flying bird!”
Each bird flies slightly above the bird in front of him, resulting in a reduction of air resistance. The birds take turns being in the front, falling back when they get tired. In this way, the geese can fly for a long time before they must stop for rest.
Researchers have also found some specialized cells in birds' eyes that may help them see magnetic fields. It is thought that birds can use both the beak magnetite and the eye sensors to travel long distances over areas that do not have many landmarks, such as the ocean.
