certain days they hold tighter than others it seems. i know when i am walking too fast because i wont have any flushes. i walk a couple feet and stop. couple feet and stop. if a woodchuck is hard to spot on the ground you'll probably never see a grouse...ive only ever seen one on the ground while hunting. only because its was "clucking" and didnt fly right away. took me a while to spot it. when i did it flew. never even got a shot off and ground pound them with a shotgun. they are well camoflauged and blend in really well. not saying it cant be done....but i find it tough. keep in mind most my hunting is middle of winter when only evergreens are green so the woods arent very thick...but then again i find 99% of my grouse in thick thick woods...stands of pines and hemlocks are always good as well as downed trees, old orchards, nasty grape vine tangles etc.

check your game commission website...see if you got grouse...id almost imagine you did...i got them in PA..and know Maine has them....should be everywhere inbetween..

btw...im hunting ruffed grouse.
