This April 2011 photo provided by Colorado Parks and Wildlife shows a male and female Gunnison Sage Grouse near Gunnison, Colo. The federal government declares 800,000 acres of land in western Colorado and eastern Utah off-limits to energy exploration to protect the Gunnison sage grouse, a preview of the potential disruption that looms when it will have to protect another grouse species that roams across 11 western states.
