- Birds like the eagle are big. They can spread their wings on a larger area.
- Such larger wings can help the big birds fly high and glide or float.
- This way, they save the energy of their bodies.
- Small birds like hummingbirds need to flap their wings continuously to hover in one place.
- The wings of smaller birds are not capable of keeping them floating without flapping.
