Alberta’s bears made famous on BBC’s Planet Earth 2 Series
Bears rub trees, but why?
Scientists in North America and Europe have been studying this phenomena with motion-based cameras and video recording devices to understand more about this behaviour in black and grizzly bears. It seems that mainly male bears rub specific trees each year during the mating season to let other male bears know of their presence. This can increase awareness of other larger bears in the area and help smaller bears avoid a fight. Since bears are so focused on feeding and breeding, a little communication can go a long way in reducing any conflicts.
