A buck pronghorn antelope herds his harem away from other bucks, marks his territory and attempts to breed during the mating season in Grand Teton National Park. The pronghorn, who spend the summer in Teton Park, have the longest big game migration in the continental United States. Some will travel over two hundred miles to their winter range in the Red Desert, where rampant industrialization for natural gas drilling is threatening this ancient migrating herd. The drilling on public lands is also causing air quality problems for humans and animals in Sublette County.

This video shows huge bison demonstrating the fighting, digging, wading, foraging, and mating behavior shown by these animals. This video is unique for several reasons. It may be the only video of bison mating. Very few videos exist of bison fighting or of pronghorn antelope fighting. No videos exist of bison watching pronghorn fight (later the buffalo broke up the fight --to be shown in more detail in another video). It may also be the only video showing male spraying behavior. The bison is the largest land animal in North America. They can reach up to 2 meters (6.6 ft) tall, 3 meters (10 ft) long and can weigh 900 to 2,100 pounds (400 to 1000 kg). The largest individuals on record have weighed as much as 2,500 pounds (1,130 kg). The heads and forequarters are massive, and both sexes have short, curved horns, which they can use in fighting for status within the herd and for defense. The American bison (Bison bison) is a bovine (related to cattle) mammal, also called the American buffalo. Two subspecies exist, the plains bison (Bison bison bison), which is distinguished by its smaller size and more rounded hump, and the wood bison (Bison bison athabascae), which is distinguished by its larger size and taller square hump. The wood bison is one of the world's largest species of cattle, surpassed in size only by the massive Asian gaur and wild Asian water buffalo. They are a keystone species-a force that shaped the ecology of the Great Plains. America's first thoroughfares were bison and deer traces, including the Cumberland Gap. Today's bison came from a few individuals that survived the slaughter of the buffalo. Once huge herds roamed the country. The animals are dangerous, and considered among the most dangerous of park animals. They will attack people if provoked. They can easly outrun humans and can run as fast as 35 mph. In Yellowstone, over 4 times as many people were killed or injured by bison, than by bears. As shown in the video, bison escape easily. Although they are large and don't look like they can, they have the ability to leap over a standard barbed-wire fence. I didn't have the camera turned on in time to catch the escapee jumping the fence. Also one very distressed young cow is shown at the end of the video. She was very vocal and called for a long time. She would run toward the stockaid. It appeared another was trapped in the stockaid and she was trying to communicate this. Buffalo are social animals who look out after each other. They are very vocal making sounds a lot of the time. Often these are a moo or low grunt. They like water and will stand and wade. They also wallow in the dust. The bison is closely related to cattle and able to breed with them. Bison and pronghorn antelope grazed together naturally in the great plains of the west. Bison (Bison bison), the pronghorn (Antilocapra americana), and the prairie dog (Cynomys ludovicianus) form a grazing association on the northern United States mixed-grass prairie. The pronghorn (Antilocapra americana), also called the pronghorn antelope or prong buck, is a species of ungulate inhabitating interior western North America. It is the only surviving member of the family Antilocapridae.[ It is thought to be the fastest land mammal in the New World. The top speed may be as high as 86 km/h. It is often cited as the second-fastest land animal, second to the cheetah. It is the fastest in sustained speeds because it can sustain high speeds longer than cheetahs. It probably evolved its running ability to escape from the recently extinct American cheetah, because its speed greatly exceeds that of extant North American predators. Its gaits also include a distinctive pronk.

Visit http://ourpubliclands.org to join us. For 6,000 years, a pronghorn herd has migrated from present day Grand Teton National Park in Wyoming into the Upper Green River Valley, where the animals spend the winter before returning to the park in the spring. Over the past decade, a natural gas extraction boom has transformed the antelopes' winter range into a spider web of roads, drilling rigs and compressors.

While most people would associate the prairie with the American Bison, the most characteristic large mammal of the Great Plains is the Pronghorn. Pronghorns are true American natives, found nowhere else in the world. they have roamed the plains and deserts of North America for at least the last million years in substantially the same form. One can truly call this animal unique: he is the lone member of his family, Antilocapra americana, which literally means the "American goat-antelope." The Pronghorn's speed and its remarkable eyesight are adaptations for life on the prairie. It needs to be able to spot predators such as coyotes and wolves as far away as possible. And, since there is no cover for it to hide in, it needs to be able to outrun any predators that manage to sneak within striking range. It can do both easily: it is the fastest land mammal in the world. It can sprint as fast as 60 mph and can sustain a speed of 30 mph for miles! The African Cheetah is often credited with being the fastest, but it is only a sprinter who flags out after a few hundred yards. No other land mammal can keep up with the Pronghorn over a long distance. Pronghorns will flare out the white hairs on their rump when alarmed. This serves as a warning to the other members of the herd. The young are born in late May or early June with about 60% of the births being twins. At birth, fawns weigh 5 to 6 pounds and lack the spots that are characteristic of deer and elk fawns. The newborn do not have an odor and instinctively lie motionless for hours. This is their main defense from predators such as bobcats, eagles, and coyotes. Visit WWW.STOCKSHOT.NL for highres version or broadcast video footage. More wildlife available!

This hunt was a limited draw hunt in New Mexico. The rut was in full swing as I took this buck. He taped out at 14 1/4" long.
