I thought this was pretty cool...
Black bears, brown bears, mountain lions, elk and deer; these are just a sampling of the critters caught on a game camera visiting this one tree in the Kananaskis Country recreational area in Alberta, Canada. These images were taken during May and June 2013 as a part of a research project. I especially enjoyed watching the mother bear and her three cubs hanging out and rubbing on the tree. At times, it looked as if they were dancing.
Scientist say bears rub on trees not to scratch an itch, but to communicate with one another. If so, there's a lot of communication going on at this one spot. Some scientists speculate female bears rub on trees as they come into oestrous. An article published on Lifescience.com refers to a study that suggests male bears mark trees to get to know each other better, which could reduce fighting among the bears over female mates.
Scientists believe cubs rub on trees to protect themselves from aggressive male bears. When an aggressive male is in the area and is trying to chase the cubs away so he can mate with their mom, the cubs will often rub on the same tree the male has used. They'll often visit the tree two or three times a day, sometimes within an hour of a big male. Researchers believe that smelling similar to the male bear might make the cubs safer, as related animals smell similar and animals are less agressive toward relatives.
