Big Bucks

Seen Big Bucks at night moving around and they are not swift silent and deadly! more like thunder clatter boom boom boom,now bears are just plain ole ka-thud ka- thud mosy-ing along sniffing the ground and air.seen it with nvg's.although the black bear does look like a moving bush in the dark.So Bigfoot 300plus pounds is making tracks and sounds but what is that sound-besides the screetches and howls.woodknocking is unknown also.could be alot of woodland animals and birds doing that.Assume-ing they are hunter/gatherers then they are going to be having lookouts and some kind of formation for moving around and gathering undetected or at least quasi/military?
