This is the time when the vegetation around us turns brown, readying itself for freezing air and snow.
It's also the time of year when bears have one last flurry of activity. On 10/2, a bear approached a sad bear-marking tree. It's "sad" because mountain bikers decided to widen a trail, and they cut off all its branches. It's just ahead of the bear in this photo.
These marking trees are so important to bears that they keep marking them, even after humans have denuded them.
This is a beautiful sow!
A few miles away, trail cams captured other bears marking trees like crazy. A small sow first marked a tree. Then, Milton Sr. did his own dance. Milton Sr. is the long-term big male of our area. He was badly injured a few years ago, and another big male ("Tiny") tried to take over the territory. Since then, they've both patrolled the area, often getting into "marking wars" where one marks over the other one's scent as often as they can. That happened in this video.
Happy very late autumn from the Rockies!
