I was tracking a buzzard Sunday evening on my dog walk. We are blessed to have several nesting pairs locally and see them on a regular basis.
Now I'm new (ish) to birding and am really only interested in birds of pray and so far, I've taken hundreds of shots and disregarded the lot. This shot was taken for the hell of it and despite loads of pp, I ended up resetting the whole shot back to what the camera took and just sharpened it a little.
Lens was my 70-200 OS Sigma at 200mm, f22. 7D set to Av giving 1/320sec, ISO400.
The Buzzard had had enough and headed for the nest.

I wouldnt use F22 for bird-in-flight shots its far too small.
Most bird photographers would have their aperture set to around F5.6 or F7.1. Use whatever ISO you need to keep the speed up.
If you are after bird in flight shots then obviously AI servo is the setting to have it on - the tracking sensitivity would depend on whether its clear background or slightly cluttered ie lots of trees. Clear background should be on a faster tracking sensitivity and cluttered should be set slower to enable you to follow and track the bird.
Hope that is of interest.
