We met this bull snake in open shortgrass prairie in southeast Colorado a week or so ago. He was very amicable to the filming process, even crawling over the camera several times. this was filmed at night using an attached led light panel. Bull snakes are constrictors that feed on mammals and birds as adults and grow to around 6 feet long. They are common in a much of the central United States and range north into Canada and south into northern Mexico. Usually they are hard to approach without triggering their defensive behavior. This individual had no problem with us being around and just went about its business.
