Jim Hart of Scenic, SouthDakota, displays a trophy of an Audubon Bighorn Sheep shot on SheepMountain in 1903 by Charley Jones. [27], Bighorn sheep live in large herds, and do not typically follow a single leader ram, unlike the mouflon, the ancestor of the domestic sheep, which has a strict dominance hierarchy. Predation primarily occurs with lambs, which are hunted by coyotes, bobcats, gray foxes, wolverines, jaguars, ocelots, lynxes, and golden eagles.[24]. In the Bighorn Canyon National Recreation Area book, storyteller Old Coyote describes a legend related to the bighorn sheep. [32] Lambs born earlier in the season are more likely to survive than lambs born later. Game and Fish issued five licenses in 2017 and all hunters were successful at harvesting a ram. [28] Bighorn sheep exhibit agonistic behavior: two competitors walk away from each other and then turn to face each other before jumping and lunging into headbutts. [20][25][26] They are considered good indicators of land health because the species is sensitive to many human-induced environmental problems. Most births occur in the first two weeks of the lambing period.

Thousands of hunters across the country apply to hunt them every year, but only a few states offer a hunt, and very few hunters ever draw. Another tactic is coursing, which is when rams fight for an already tended ewe.

[1], Bighorn sheep were among the most admired animals of the Apsaalooka (Crow) people, and what is today called the Bighorn Mountain Range was central to the Apsaalooka tribal lands. Badlands National Park asked viewers to count the number and many people failed at figuring out just how many there are hidden in the butte. Horns are present in both sexes, but they are bigger in males (rams). Ewes (females) also have horns, but they are shorter with less curvature. With the Sioux defeated and the pioneers long gone, the Badlands are a picturesque backdrop for herds of bison. The history of bighorn sheep in the southern badlands is a roller coaster tale. [31], Bighorn ewes have a six-month gestation. At the beginning of the 1800s, there were an estimated 1.5 to 2 million bighorn sheep in North America. By 1900, the population had crashed to several thousand, due to diseases introduced through European livestock and overhunting. [48] For many years large herds of bison roamed theBadlands during the summer months. Rocky Mountain bighorn sheep were brought to Badlands in 1964, and coyotes roam throughout the park as well. [7], The Rocky Mountains and Sierra Nevada bighorn sheep occupy the cooler mountainous regions of Canada and the United States.

The Bighorn River, another tributary of the Yellowstone, and its tributary stream, the Little Bighorn River, were both indicated on Clark's map and did retain their names, the latter being the namesake of the Battle of the Little Bighorn. Badlands bighorn sheep or Audubon's bighorn sheep, O. c. auduboni, occurred in North Dakota, South Dakota, Montana, Wyoming, and Nebraska.
