Birds fly because they have wings! ๐ฆ Their wings are like arms, but covered with feathers. When they flap their wings up and down, it pushes the air and helps them go up in the sky. ๐ค๏ธ
Birds are very light, and their feathers help them stay in the air. They can glide like a kite or flap fast like a hummingbird!
Birds fly thanks to their special wings, lightweight bones, and strong muscles! ๐ฆ Their wings are shaped like an airplane's wingsโcurved on top and flat underneath. This shape helps air move faster over the top, creating lift that pushes them up.
When birds flap their wings, they push air down, which lifts them higher. Some birds, like eagles, can glide for hours without flapping!
Bird flight is a mix of aerodynamics, anatomy, and energy! โ๏ธ Birds have hollow bones to reduce weight, and their feathers are arranged to streamline their bodies. Their wings generate lift due to the Bernoulli principleโfaster-moving air above the wing creates lower pressure, lifting the bird.
Flight muscles (like the pectoralis) make up 15โ25% of their weight! Different birds fly differently: hummingbirds hover, ducks paddle, and falcons dive at 200 mph (320 km/h)!
