Going off my previous comments on this subject, and in agreement with what 411a said, in a jet you're not gonna see them in time to do anything about it, like I said, I've seen people try, didn't make a difference (maybe they would've even missed if nobody tried rolling the plane a bit), I once tried to avoid a flock in a 1900, but we were only doing 120 knots at the time so I just pitched down a bit and flew under them, did the same doing about 100 knots in a 207 at 2000 feet off a cliffside where they like to nest. I think that, realistically, there is a speed limit as to where you can see one in time and do something useful about it, needless to say, 99/100 jet aircraft are going beyond that speed limit.
