they will usually flush into the wind, but can catch it and turn...then be out of range just that quick! Hopefully the flush will be close enough, and you react quickly enough, to get on 'em before they catch the wind...otherwise you are likely just sending them off with a bang.
Windy for me has been good time to hunt the cattails...spooky birds might want open fields in the wind, but a few will want to hunker down in the thick cover...those are the few that are accessible and the dog can roust them out for a close shot
