I get everything except conclusive video/photographic proof.
I found footprints, simple stick structures, rocks getting thrown at me-even got video of a rock hitting a tree next to me, I hear sticks breaking, wood knocks, rock clacking, and what sounds like bluff charges.
I have not found any nest where they "live", but the top of the hill is thick and a large area, about 100 acres out of about 10,000 total summer range acres, but tough to investigate.
I have found what I would call, look-out nests, where they can sit and survey areas and trails leading up to the hill, always at the foot of eastern hemlock trees.
I seen one once, looked like a dark refrigerator sized object moving through the trees, upright, about 25 to 30 yards from me, I was recording video at the time but
my camera was at elbow height and not eye level, so I didn't get it on tape.
very frustrating.
why do we have such an assortment of forest creatures? Maybe because they don't migrate and stay in areas they are used to.
just my thoughts after 11 years investigating
