Barn Swallow in Flight

Catching a shot of a barn swallow in flight is quite a challenge. These little guys are quite fast. I was walking across a field and several appeared to be following me in a rapid dance. Apparently, they were feasting on little invisible insects that I had stirred up. I snapped a lot of high speed pictures, but had difficulty keeping them in the frame. Also, my Automatic Focusing for the most part could not keep up with their quick changes in the direction of their flight. Several hundred of shots later, I did get a couple worth presenting. Thank God for digitial photography.
