The bears emphatically mark a tree that leans across a trail every year. It appears to be in the "path of destruction" by the bulldozers widening it into a road by destroying all the trees. It is breaking my heart. I have attempted to get them to spare some trees with no success.
Tiny the Black Bear is one of the main bears who marks it. You'll see his trademark "sitting style" of tree marking throughout the video. It's fun to observe how each bear has his own style of putting their scent on the tree. One young bear only sniffs, perhaps out of deference to the older and bigger bears.
Sorry to be late with this. Our internet goes down randomly. It's a price for living rurally but it's worth it.
