I always use single point expanded for birds in flight, both on my 7D and 1D4. You are right though, those ducks haul ass in the air! I have far more misses than hits. I was luck on this one as I was even using my 100-400 versus my 400 prime, which tends to focus slower. As I said, I was on a roll that day
