I almost ran into these

I was driving in the north up a hill. This truck in front of me was going slow so I tried to pass him. When I went out from behind him I had to stop for a cow that was just wandering in the middle of the road. On the way back there were a few in one spot so I decided to stop and take their picture. At least one started staring at me and that's when I noticed horns on his head! Could he have charged at me? I might have made him think I was a threat since I stopped there on my bike facing them.
