Swamp--just to keep this a "survival" post--we call Spruce Grouse "fool hens"--they will hang around your camp and can be killed with a swift whack with a stick or well aimed rock.
while i've never done that i surprized some guys who had done just that on a portage trail who took me for a Ranger because of my all tan canoeing clothes and at first were trying to hide the dead birds..when they saw i was not with the DNR they held them up like a stringer of Walleyes--
