I happened to have my camera ready, when this bird of prey flew over. Not sure what it is (buzzard?), my knowledge of birds is very limited. However, I'm always envious seeing a living creature soar through the sky without any mechanical help whatsoever. When I was a young boy, I didn't dream of becoming a pilot. I dreamed of becoming an eagle.
The pictures were taken with my 75-300mm zoom at 300mm. On the Canon 20D that amounts to almost 500mm. And in spite of the image stabilizer it's pretty hard to take stable pictures out of the hand while following the bird with the camera.
