Depends.. the word I would use most ofter when it comes to bison is very "Unpredictable".. They can be very calm..and suddenly, for whatever reason, something gets them going and its game on..

The one I shot in this story was very wild.. He was bedded down in a small drainage as I come riding around the corner heading up the draw .. first I saw a very nice coyote..who really didn't know what to make of me..an usual sight for them I suppose to see a human on a horse, trying to figure out if I was a threat or not.. I experience similar experiences often from the coyotes and other wildlife, even elk let me get closer than normal on a horse.. especially if I get off before they see me and walk on the off side of the horse..at times I have gotten amazingly close ..

Anyway, once the bison saw me, he jumped up and immediately ran about 50 yards, then turned and faced me.. I was walking towards him on my horse and he turned again and ran about another 100 yards. once again he turned to face me.. saw I was not galloping after him, he ran a good 5 to 600 yards before he turned this time.. I was riding faster on my horse, so was keeping up with him when he stopped to see where I was..then he turned and ran again for a good half mile before stopping to turn and find me.. WE played that game for over 4 hours.. going through creeks, fences, brushy draws, timber, etc.. finally he was exhausted and decided to hold up in the willows.. which lead to his demise..

Most of the bison I have dealt with are NOT close to cattle as to their disposition.. semi-wild at best..many are just plain wild...especially if you are trying to work with them..

Angus bulls are much easier...You can usually move bulls a couple times per day and they will tolerate you.. start pushing them more and they to can get a bit unhappy..
