"Another amazingly great and unquestionably rare footage from Yellowstone Videos! I just found your channel yesterday and I am blown away by the events and interactions between species of wildlife you capture on video! To get footage like this, and the other vid featuring the black and grizzly bears squabbling over that dead bison, must require a ton of time out in the bush just watching things. Thank you for your effort and dedication!" - @de1018

Yellowstone male grizzly moves in on a female but she still has her two year old cubs. This could get aggressive very quickly and go very bad for one of the two. Watch to the end and get a very unexpected surprise you don't see very often with grizzlies.
