Birds fly to get to their food source, whether that means foraging locally or migrating hundreds of miles to get to feeding grounds. Where birds nest is a by-product of getting to their food source. Flight is also very useful for evading predators.

∙ 16y agoGliding uses less energy than actively flapping their wings
They do so by angling their wings to maintain a lower pressure on the top of the wing than the bottom. The slower a bird is moving, the less this gliding effect will work and they will have to flap again to gain speed.

∙ 15y agoAll flying animals (birds, bats, insects, etc) have some sort of large air-catching surface that they use either for propulsion (true flight) or gliding (as is done by "flying" squirrels). Some scientists believe that birds evolved the ability to fly after first having the ability to glide.
Bird flight depends on two separate mechanisms -- the downstroke of the wing pushing against the surrounding air, and the airfoil shape of the wing creating lift as it moves forward through the air, in the same way that an airplane does. Both require the wing to have a relatively large surface to move the bird upward.
A detailed discussion of bird flight can be found at http://en.wikipedia.org/wiki/Bird_flight.

∙ 13y agoThe skeletal adaptations that gave theropod dinosaurs an advantage of better balance or a swift strike to capture prey combined with feathers that may have served as insulation or an impressive display to potential mates to provide the components of a basic wing. A significant advance in flying ability came with the evolution of the alula, a tuft of specialized feathers attached to the thumb that alter airflow and allow control and maneuvering at slow flying speeds, important for controlled takeoffs and landings.
