Lewis first observed the greater sage-grouse on June 6, 1805, near the mouth of the Marias River in Montana. He wrote one of the most detailed ornithological descriptions of the expedition at Fort Clatsop on March 2, 1806, calling it the “cock of the plains.” His description was so thorough and accurate that it rivals the work of professional ornithologists of the era. The species is now threatened due to sagebrush habitat loss across the American West.
