As winter begins to thaw in Wyoming’s high, cold desert, male greater sage grouse strut in a tousle of fanned feathers and jiggling, yellow air sacs only a female sage grouse could love. The hollow water droplet “plops” and coos of their mating calls echo across the Red Desert landscape. As if the sight of one of these birds prancing about wasn’t enough, males gather en masse trying to outdo each other in front of the highly discriminating and perusing females.
The Red Desert is one of the last strongholds for sagebrush wildlife, including the greater sage grouse, says Erik Molvar, executive director of the Biodiversity Conservation Alliance. The birds face serious habitat loss and declining numbers all throughout the West — a poor sign for an animal that used to be known for its wide distribution.
But even though one stands a good chance of seeing the bird on a visit, Greater sage grouse are poster-animals for wildlife conservation in the Red Desert. Their numbers have fallen 90 percent in the Red Desert during the last 50 years, says Lorraine Keith, BLM public affairs officer and former sage grouse biologist in Rock Springs, Wyo. The cause of the decline is unclear, though human disturbance likely plays a significant role in their falling numbers.
The U.S. Fish and Wildlife Service recently considered and rejected the bird for endangered species listing. Biologists struggle to understand just how sensitive the birds are to development, and this gaping hole makes managing the sage grouse and their environment difficult, especially with growing demand for energy development. But as biologists concentrate more efforts on monitoring population trends, the greater sage grouse is once again up for endangered species listing, and the U.S. Fish and Wildlife Service expects to announce a decision sometime this summer.
Stay tuned for more information on the sage grouse’s status as decision time approaches. In the meantime, you can read a current report by the Fish and Wildlife on the birds here.
