Thanks for comments guys!
Yes not the best shots but had the urge to share these cos they were so majestic in flight. It was close to sunset and I was on my way out when I saw this bird. Only had time to set to ISO400 and went shooting away leaving the camera to do the settings. Zoomed all the way at 200mm (35mm equivalent of 400mm). For the first picture was set at F6.3 1/250 shuttle speed; and the second at F5.6, 1/160 shuttle speed. The pictures are cropped, and magnified with PS, so quite a bit of noise.
The flight was over in a matter of seconds. What settings would be better to shoot birds in flight?
Cheers
