How do feathers work?
This six-part lesson is designed to teach you the basics of how birds fly. Introduction Birds have beautiful feathers and lovely songs that bring joy and wonder to us humans. And flight is the feature that probably captures the human imagination more than anything else. For millennia, people have watched birds in the sky and wished we could fly, too. There are almost as many ways of flying as there are kinds of birds. Albatrosses glide and soar with long narrow wings stretched out, sometimes staying aloft for hours without a single wing beat. Hummingbirds, on the other hand, can't rest their wings for even a second in flight.
Birds have wings covered with feathers, which allow most of them to fly. Most birds also have extremely good eyesight and hearing. Birds have evolved many features to make flight possible. The skeleton is strong but light, with a large breastbone to support powerful muscles for flapping wings up and down. The wings themselves are curved on top, flatter beneath—air travels faster over the upper surface, producing lift. The long tail helps with direction and balance; strong legs assist with takeoff. Birds of prey are powerful fliers and have superb eyesight, allowing them to spot prey on the ground even when they are hundreds of yards up in the air.
A small, dark goose - the same size as a mallard. It has a black head and neck and grey-brown back. There's so much to see and hear at Minsmere, from rare birds and otters to stunning woodland and coastal scenery. Explore the little pools of amazing sea life that are left by the tide on the rocks around our coast. Feathers are the magic material that cover the bodies of all birds and help them to fly. But they're not just for flight.
Pressure: a force against an object. Like when you use your hand to push a door open.

One of the requirements for heavier-than-air flying machines is a structure that combines strength with light weight. This is true for birds as well as planes. Birds have many physical features, besides wings, that work together to enable them to fly. They need lightweight, streamlined, rigid structures for flight. The four forces of flight — weight, lift, drag and thrust — affect the flight of birds.
A bird is designed for flight. The combination of light weight, strength and shape, as well as precision control , is largely responsible for giving birds their special ability for sustained flight. Every part gives maximum power with a minimum of weight. The heavier the animal, the bigger its wings need to be. The bigger the wings, the more muscle is needed to move them. Although it looks like feathers grow all over a bird, they actually grow in specific areas called feather tracks.
