In your experience is it worth pursuing a bird after you get busted? Or better to move on to find another?  I hunt big hardwoods all rolling hills and hollars, no fields.  Put a few birds in the dirt last year, but also got busted by a couple that were working in.  After they putted and ran off before I could get a shot, I chalked it up and moved on to find another bird.  Should I have repositioned, chased after, pursued to try to get back in the game?  At the time I figured there was no point, but afterwards I got to thinking about whether they would have still played ball if I repositioned and tried a different call.
