American Pronghorn
Social Adaptations and the Ghosts of Predators Past
John A. Byers
University of Chicago Press, 1997
Pronghorn antelope are the fastest runners in North America, clocked at speeds of up to 100 kilometers per hour. Yet none of their current predators can come close to running this fast. Pronghorn also gather in groups, a behavior commonly viewed as a "safety in numbers" defense. But again, none of their living predators are fearsome enough to merit such a response.

In this elegantly written book, John A. Byers argues that these mystifying behaviors evolved in response to the dangerous predators with whom pronghorn shared their grassland home for nearly four million years: among them fleet hyenas, lions, and cheetahs. Although these predators died out ten thousand years ago, pronghorn still behave as if they were present—as if they were living with the ghosts of predators past.

Byers's provocative hypothesis will stimulate behavioral ecologists and mammalogists to consider whether other species' adaptations are also haunted by selective pressures from predators past. The book will also find a ready audience among evolutionary biologists and paleontologists.

Built for Speed
A Year in the Life of Pronghorn
John A. Byers
Harvard University Press, 2003

North America’s fastest mammal, the pronghorn can accelerate explosively from a standing start to a top speed of 60 miles per hour—but it can also cruise at 45 miles per hour for many miles. What accounts for the speed of this extraordinary animal, a denizen of the American outback, and what can be observed of this creature’s way of life? And what is it like to be a field biologist dedicating twenty years to studying this species? In Built for Speed, John A. Byers answers these questions as he draws an intimate portrait of the most charismatic resident of the American Great Plains.

The National Bison Range in western Montana, established in 1908 to snatch bison from the brink of extinction, also inadvertently rescued the largest known remnant of Palouse Prairie. It is within this grassland habitat—home to meadowlarks, rattlesnakes, bighorn sheep, coyotes, elk, snipe, and a panoply of wildflowers—that Byers observes the pronghorn’s life from birth to death (a life often as brief as four days, sometimes as long as fifteen years) and from season to season. Readers will also experience the vicarious pleasures of a biologist who is eager to race a pronghorn in his truck, scrutinize bison dung through binoculars, and peer through the gathering dusk of a rainy evening to count the display dives of snipe.

A vivid and memorable tale of a first-rate scientist’s twenty-year encounter with a magnificent animal, the story of the pronghorn is also a reminder of the crucial role we can play in preserving the fleeting life of the native American grassland.

Pronghorn and Human Interaction in Early America
Richard E. McCabe
University Press of Colorado, 2010

A Wildlife Management Institute Book

In this lavishly illustrated volume Richard E. McCabe, Bart W. O'Gara and Henry M. Reeves explore the fascinating relationship of pronghorn with people in early America, from prehistoric evidence through the Battle of Little Bighorn in 1876. The only one of fourteen pronghorn-like genera to survive the great extinction brought on by human migration into North America, the pronghorn has a long and unique history of interaction with humans on the continent, a history that until now has largely remained unwritten.

 With nearly 150 black-and-white photographs, 16 pages of color illustrations, plus original artwork by Daniel P. Metz, Prairie Ghost: Pronghorn and Human Interaction in Early America tells the intriguing story of humans and these elusive big game mammals in an informative and entertaining fashion that will appeal to historians, biologists, sportsmen and the general reader alike.

Ecology & Mangemt: Ecology and Management
Bart W. O'Gara
University Press of Colorado, 2004
One of the fastest land animals on Earth (second only to the cheetah), the pronghorn can reach speeds of more than 50 miles per hour. It also is one of the most fascinating of all animals. For many people, the pronghorn was nearly as much a symbol of the American West as was the bison; for some, it still is. Eliminated from much of its historic range by the early 1900s, this unique North American big game species has experienced a remarkable recovery and now is found throughout the western United States, Canada, and northern Mexico. Thirty years in the making, Pronghorn: Ecology and Management contains the most comprehensive information on the behavior, physiology, migration, taxonomy, and management of this extraordinary animal.

Full chapters are devoted to distribution, nutrition and food, diseases and parasites, ecosystem management, hunting, and much more. The principal authors—the world’s preeminent pronghorn biologists, Bart W. O’Gara and Jim D. Yoakum—conclude with a thorough discussion of the future of pronghorn and their management. With 23 chapters that include contributions by 10 other wildlife professionals and more than 850 illustrations, including original artwork by Edson Fichter and Daniel P. Metz, Pronghorn: Ecology and Management is the definitive work on the species.
