How Do Birds Soar in the Air?
Bird wings are shaped in a unique way, so that they create pressure differential or tiny tornadoes on their wings. That lifts them into the air. Birds don’t just fly because of their wings. Sure, wing help them get off of the ground and helps them steer, but is one MAIN thing that bird has inside of its body! Birds have hollow bones. These hollow bones make the bird lighter so that it can fly! Birds also do not have bladders. Birds do not pee, and they don’t have to store that pee in their bladders. That makes the lighter. These are the nifty adaptations birds have to fly!
