Bullsnakes
About bullsnakes
This nonvenomous snake is of the most common, and largest, of snakes seen in Colorado, but often mistakenly confused for rattlesnakes. When threatened, this snake can hiss and mimic rattlesnakes by vibrating its pointed tail to sound like a rattling tail. Bullsnakes can be identified by the oval-shaped head, round pupils and yellowish or cream coloring with dark blotches. Bullsnakes are very beneficial because of their appetite for rodents, as well as birds and bird eggs, which they kill by suffocation or constriction. They are found in a variety of habitats, including riparian areas and woodlands areas.
