You may remember from past posts on this site when I have warned people not to crowd or get to close to wildlife? Just like people animals have their personal space that they do not like to have invaded. In most cases wild animals do not react with the best of manners or concerns for the intruders welfare.
Check out the video link below to see what happens at Yellowstone National Park when a bull elk starts to feel a bit encroached upon.
