At an airshow many years ago, I grabbed a quick photograph of a flock of birds. The Atlanta smog was making the planes that I had come to see hazy specks. These low flying creatures were a nice change. Though the airplanes were impressive, I have always been fascinated by the fact that birds accomplished flight millions of years before man.
We have all seen photos birds in flight, but I thought this one was interesting because you can see all the various stages of flight... from full wing extension to the wings pulled all the way into the body. A few feathers, bones and muscles = flight.
