I got these a couple weeks ago.
A good friend in Sitka (Dillon’s Man) and his buddy had set up a Trail Camera by a Grizzly Bear rubbing tree.
The camera is activated by motion through an infrred sensor.
A rubbing tree is selected by Grizzlies as a sort of "Message Board"
They display numerous behaviors, including scent marking by rubbing against it, hugging it, and urinating around it.
They also bite it and leave claw marks to indicate their size.
All this is said by researchers to mark territory, and serves to avoid encounters with big boars that are usually deadly to other bears, including smaller bears, black bears, sows with cubs and grizzly cubs.
This first photo show a "big boy" with an unusual light collar marking around his neck and shoulders.
This second photo shows a huge boar with a very large ass end
(which continues to grow over their lifetime).
Finally, this is one that is a good reason to carry extra underwear camping in grizz country,
in case you should encounter this!
