I used the Miles Green "method" posted earlier. I also updated the firmware. It works great. I have tracked birds flying across the Y axis as they passed behind tree branches that might've fooled the system. I'm not saying it's perfect; I'm saying that using AF-C and all 25 points has taken my BIF photography from "non-existent" to "not bad and occasionally great".

I find that a minimum shutter speed for a BIF seems to be around 1/1250. Smaller birds closer to 1/2500. I keep my aperture around F8, though I could probably open that bit, given how far away they are most of the time (300m DA*, which isn't the fastest-focusing lens I can think of).

Keep plugging away at it.

I will try his method also.

But right now, spot focus, BBF until the bird comes close, then 1/1600 and f/7.1 gives some keepers, see below.
