The lens's biggest drawback for birding is focus hunting.

That's when you need quick-shift focus. Do you have the DA version or DA L?

Once it hunts back toward minimum distance (and why does it always err in that direction?), I don't find much advantage in putting it back manually over just trying again with autofocus. It's no quicker nor is it better for keeping the target in view, at least not for me so far.

I agree, it invariably starts searching for focus by racking inward. I've also found that it frequently misses focus when racking from close to far. I try to make sure I reset the lens to beyond the target before I start to auto-focus. If I don't use quick-shift to nail focus, I at least use it to bring the focal point past the target and try to auto-focus again.
