The Sagebrush Sea

It’s been called The Big Empty – an immense sea of sagebrush that once stretched 500,000 square miles across North America. Yet it’s far from empty, as those who look closely will discover. In this ecosystem anchored by the sage, eagles and antelope, badgers and lizards, rabbits, wrens, owls, prairie dogs, songbirds, hawks and migrating birds of all description make their homes.

Sage-Grouse Display Lekking Behavior

In the springtime, male greater sage-grouse (Centrocercus urophasianus) gather in groups, called leks, to compete for females. Males guard a territory a few meters in size (on average) and try to attract a mate by ruffling feathers and making a distinctive noise produced by air sacks in the chest.

    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 hardscrabble birds and mammals. And among those that have adapted to survive here are birds found no place else – Greater Sage-Grouse.
