Musk ox tribe making the protective formation
Very interesting episode (unfortunately, I missed a couple of seconds in the beginning):
Couple of cyclists appeared from the small hill on the road, and musk ox tribe considered this situation dangerous. They backed off (even the "chief" ox, but only a couple of meters), the elders turned to the "enemy" while the young ones stood in the back of group.
This formation clearly shows the hierarchy in tribe.
After some pause and conversation, cyclists decided to make a hook around the tribe. It was successful.
