Colorado’s official “State Animal,” as designated by the Colorado General Assembly in 1961, is the Rocky Mountain Bighorn Sheep. This majestic animal is only found in the Rockies. You can learn more about this animal by reading their species profile from the Colorado Division of Wildlife. Also, the CDOW has created a great video about Rocky Mountain Bighorn Sheep. CDOW has also created a 10-year management plan for Bighorn Sheep in Colorado, available online or in our library.
