Because they don't run. Just Kidding! Here is a good answer i found 4 u... All animals need some kind of locomotion, or ability to move. Birds are lightweight animals that developed the ability to fly in order to adapt to their environment. Flying gave them the ability to escape their predators, as well as make them better hunters. Flying also allows them to escape nasty weather and migrate to warmer temperatures. It's important to note that not all birds can fly -- the ostrich, for example, adapted to its environment by developing the ability to run very fast! Here is some stuff on feathers if u are interested Feathers are one of the most prominent features of a bird's anatomy, and they are unique to birds. Every bird has feathers and everything that has feathers is a bird . Feathers perform a number of functions for a bird. Firstly, they provide insulation, this is very important in a warm blooded animal (body temperature of most birds is maintained at around 40C). It is believed by most scientists that this insulating effect was the primary force driving the evolution of feathers, i.e. ancestral birds developed feathers to keep themselves warm. Feathers also protect birds from UV light. Secondly, feathers allow for flight. Scientists believe that flight evolved in birds as a result of their possessing basic feathers and that this added selective pressure to the evolution of feathers making them larger, stronger and refining their structure. Thirdly, feathers control what a bird looks like. A plucked chicken or pigeon looks very different to a fully feathered one. Feathers supply the bird with colours allowing for camouflage and secondary sexual characteristics and sexual display. Consider the tail feathers of a
