Trying to photograph birds in flight, even big birds, is not easy. First you have to find them in your view finder, then zoom in while panning the camera to follow there flight. I did manage to get a couple of photos this evening, the sun was already below the horizon so the light was not so good.
Click to enlarge.
A pair of Egyptian geese almost overhead, one with the wing in the down stroke and the other up. you only reallise how fast they are flying while you are trying to follow them with the camera.
This photo was taken at a long distance, what I though was another Egyptian goose turned out to be a African sacred Ibis. (Threskiornis aethiopicus)
These photos of the Ibis were quite severely cropped so the quality is not so good when enlarged.
Will spend more time watching the sky while I'm walking so I can react faster when I see birds flying my way.
