2 - Why are birds able to fly?

Birds are able to fly due to a combination of their body shape, muscles, and feathers.

1. Light bones: Birds have hollow bones, which makes them lighter and more suitable for flying.
2. Wings: Their wings act like big flaps that help them lift off the ground. As they move their wings up and down, it creates a difference in air pressure, lifting them up.
3. Feathers: Feathers provide extra lift and help control the bird's movements while flying. They're lightweight and strong, which is perfect for flying.
4. Strong chest muscles: Birds have powerful chest muscles that help them flap their wings. This flapping motion is crucial for generating the energy they need to fly.

All these features work together, allowing birds to take to the skies with incredible ease and agility.
