Birds are very aerodynamic. Some birds take off like planes. Some birds can stay in the air for hours with out flapping their wings. Some birds have big wings and some have small wings. Planes are made in the same way as birds.

Birds are aerodynamic that's why they can fly. Planes are just very big birds. Some birds can fly for hours without flapping their wings. And some birds takeoff by running like airplanes. Big wings help birds fly higher and glide more.

Birds are aerodynamic. Some bird have small wings for Manuviring and going fast. Other birds have long and strong wings to fly at high altitudes. Lastly other birds have long and narrow wings to glide very far. Some birds have to takeoff while others go right away. Bird are very cool animals!!!!!!

Some birds can't fly like penguins. Some planes wings are based on the aerodynamic designs of birds wings. Some birds can stay in the air without flapping their wings for hours. Birds wings curve down and air lifts them up because of it. Birds look like their slowly gliding but there really going fast.
