I can't tell you how many times I've had elk hitting my camera's 3 or 4 times a day, think it's a sure thing, then go to hunt them and they're gone *poof*
Those elk will loiter in an area for a while, then move to the next area, sometimes of their own accord or sometimes because hunters/wolves/cats take one of them out or push them.
It ain't loggers though, they'll sit and watch a guy working equipment, get out, grease equipment, start his truck to leave and not care a bit. (hint hint)
