The feet of birds also have evolved for many different purposes to suit their living conditions. Swans and ducks have webbed feet to facilitate them while swimming in the water. The ostrich and the emu cannot fly and spend all their time on land. Over the years their feet have developed to help them run faster. An ostrich can run faster than a horse and with each step it can cover a distance of 20 feet easily.
Feathers usually cover the body, protecting the skin and providing insulation.
Usually feathers are very colourful and sometimes are arranged in a manner to provide spectacular patterns. In all species the male bird is usually more colourful than the females. 1999 - 2000 Netglance Inc. All Rights Reserved.
