Тетерев полынный (шалфейный) / Sage Grouse / Centrocercus urophasianus

The Gunnison Sage-Grouse is a spectacular but declining bird of the western sagebrush. It is restricted to seven isolated locations in Colorado and one tiny population in Utah. In early 2013, the U.S. Fish and Wildlife Service placed it under consideration for listing under the Endangered Species Act. The males have an extravagant spring display in which they puff out their bodies, fan their tails into a starburst, and make low, gurgling sounds with bizarre froglike air sacs in their chests—watch them here.
