FILE - This July, 26, 2014 file photo provided by the U.S. Fish and Wildlife Service shows a Greater Sage Grouse at the Seedskadee National Wildlife Refuge in Wyoming. A legislative rider in Congress’ $1.1 trillion spending bill would delay protections for the wide-ranging Western bird that’s been on a collision course with the oil and gas industry. The Obama administration faced a September 2015 deadline to propose protections for greater sage grouse. But the spending package agreed to late Tuesday, Dec. 9, 2014 by Democrat and Republican leaders prevents the administration from spending any money next year on rules to protect the ground-dwelling bird.
