The Gunnison sage-grouse, or Centrocercus minimus, lives south of the Colorado River in Colorado and Utah. Loss of habitat has been extremely detrimental for the animal, which requires a variety of land types for its survival, including sagebrush and wetlands. The bird is listed by the Audubon Society as one of the 10 most threatened birds in the country, but it is currently only on the U.S. Fish and Wildlife Service’s endangered list.
