AF Techniques for Bird Photography

[Jack Breakfast]

Hello there!
I thought I'd open up a friendly can of worms and ask BPN folks for some help regarding autofocus technique...
As for me, I shoot a Canon 7D and most of the time I use the central focusing point only, and switch between Servo and One Shot...
I have a feeling I can be getting a lot more out of the 7D's AF system, and would love some pointers from you folks. I stick with the center point b/c I find it difficult to switch between focusing points while busily taking pictures of moving birds...I can't seem to do it without taking my eye away from the viewfinder, and in so doing I will often miss out on good opportunities...but perhaps it's just a question of getting used to the camera's button placement and so forth...
I don't want my subject limited to the center-of-frame and will often switch to the One Shot mode, but this is only really useful for static subjects.
I am requesting your help!
Many thanks for your time and consideration.

All the best,
Jack Breakfast
