Not always- this large buck was living quite comfortably in town until this year when he followed does out into the areas away from safety, and was spotted and harvested- he was a 6x5 w/32" spread.
A couple of my favorite pics: one demonstrates how vicious a fight can be; the other of a banged up survivor I encountered (he looked pretty roughed-up... but not too bloodied!)
A friend sent me a couple of pics of an incident between two bucks in a Caliente, Nevada neighborhood where one buck killed another. Thought it a rather unusual "kill site".
