Bird Flight!

Birds have inspired humans with their ability to fly! Humans have been trying to attach man-made wings and have been trying to fly like birds. Even though we have airplanes and helicopters, we will not be able to flap wings to fly. Birds don’t just fly because of their wings. Sure, wings 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!
