One of the most overlooked ecosystems on the continent consists of a massive sea of sagebrush that stretches across 11 states in the American West. This spartan yet spectacular landscape supports more than 170 species of birds and mammals, including deer, eagles, hawks, prairie dogs, cranes, songbirds, badgers and rabbits. And among those that have adapted to survive here are birds found no place else – Greater Sage-Grouse. These grouse lead remarkable lives mostly hidden in the sage. But once each year, males emerge for days on end to strut and display as prospective mates for extraordinarily discriminating females, nearly all which mate with only one or two of them. Females must then raise their chicks on their own, with little food, water or shelter to sustain them, while plenty of predators wait for their smallest mistake. And today, they must also contend with wells and pipelines tapping the resources buried deep below. The sagebrush and the grouse carry on, but they’re losing ground.
