I photographed this Amrerican Bison bull a few days ago on Antelope Island State Park as he was drinking from a freshwater puddle formed by rains over the weekend. I wanted to capture photos of him as he lifted his head and show the water running down fron his bearded jaw.
So he drank and I waited. And waited. The bull must have been powerfully thirsty because he kept on drinking. And I waited some more. I believe he could have drank a bathtub full of water.
Finally his thirst must have been quenched and he lifted his massive head and stared at me with water dripping from his beard. I think this image was worth the wait.
PS: I was inside of a vehicle when I photographed this Bison, it is far safer doing that than by photographing on foot. Bison can be extremely dangerous.
