Typically smaller birds master the art of flight earlier than larger ones. This means the air is moving more quickly over the top surface of the wing, reducing air pressure on the top of the wing and creating lift. Basically, the only thing needed for flight is the ability to overcome the force of gravity. How do feathers work? The feathers tend to shed rain, keeping the body dry and well insulated.

Feathers are made of a tough and flexible material called keratin. Then, as the bird moves its wings up, the feathers move apart to allow air to pass through. This internal spiderweb-like structure keeps the bones light while also ensuring they are strong and flexible enough to cope with the stresses of flight.

A vane is made up of many small side branches, all linked together by even smaller branches with hooks, called barbules. As well as allowing it to fly, a bird's feathers keep it warm and dry. This is called the angle of attack. The four forces of flight - weight, lift, drag and thrust - affect the flight of birds. This is called moulting.
