The pronghorn antelope (Antilocarpa americana) is skittish but often seen around the state of Wyoming, USA. My personal favorite encounter was seeing an antelope fawn being born then taking its first steps in Grand Teton National Park. This shot is from Casper in the center of the state, and bears a striking resemblance to a cave drawing in Lascaux, France, according to a French artist who is knowledgeable about rock art.

Interesting background on Pronghorn Migration…
“The pronghorn (Antilocarpa americana) that summer in Jackson Hole migrate annually between there and wintering areas in the Green River basin. Documented round trip migration distances from 175 to 330 miles make this the longest known terrestrial animal migration in the 48 contiguous states.” source: USDA Forest Service, Bridger-Teton National Forest, Wyoming.

“Ancient Pronghorn Path Becomes First U.S. Wildlife Migration Corridor
JACKSON, Wyoming, June 17, 2008 (ENS) – To protect the 150-mile round-trip movement of pronghorn in the Greater Yellowstone ecosystem, the U.S. Forest Service has established the nation’s first designated wildlife migration corridor – the Path of the Pronghorn.
This seasonal movement of pronghorn antelope, Antilocapra americana, between Grand Teton National Park and the Upper Green River Valley in northwestern Wyoming is the longest remaining migration of any land mammal in the lower 48 states.

“This represents a tremendous conservation victory and demonstrates that by working together we can find solutions to preserve our nation’s wildlife heritage,” said Dr. Kim Murray Berger, a biologist with the Wildlife Conservation Society who has studied the pronghorn migration since 2003."
