Bighorn sheep
The Sheepeater Indian War of 1879 was the last Indian war fought in the Pacific Northwest portion of the United States; it took place primarily in central Idaho. A band of approximately 300 Shoshone people, the Tukudeka, were known as the Sheepeaters because they ate Bighorn sheep Rocky Mountain sheep akin to other bands of Shoshone who were known by those sacred foods they lived amongst and ate by hunting, fishing, and gathering them, such as: the Agaideka; Salmoneaters, Tukadeka; (Bighorn) Sheepeaters, and different bands across Shoshone homelands.. Hence, because the Tukadeka bands were proficient at hunting they were known as 'Sheepeaters' as Bighorn Sheep were a main staple of food, clothing, and tools.
