The biggest mammal on Antelope Island is the American Bison. There is a herd of about 500 bisons free roaming on the island according to the Utah State Park website. They seem to stay away from the part of the island that is easily accessible by car. I have never seen more than ten at a time. That's alright with me, bisons are such beautiful animals that I get excited even if I come close to just one of them. This bison bull was relatively close to the road so that I was able to shoot out of the safety of my rental car. The bull was feeding the whole time I watched him and it took forever to get a clear view of its face. Light was great, it was wildlife photography fun at its best....
