The main settings for AI Servo are in C.Fn:Autofocus.

Let's start at #7 and work backwards.

Depending upon how steady you are, how far away the bird is and what kind of background you want to select one of the first three.

#6 I'd use 0

#4 and #5. What good is speed if you don't have focus. So go with focus on both.

#3. This is for switching between focus points. If you are using single point this does nothing. Otherwise I'd go with +2.

#2. I'd go with +2.

#1.

And the reason I left it for last. If you are in a situation where the birds are flying thru trees, etc then once focus is locked on you want to keep it. So go with -1 or -2.

If you have a nice clear sky, your birds are generally above the tree line and moving to and away a lot then you want the camera to keep refocusing the lens as the birds move. So +2 would be good.
