Lewis and Clark were the first to scientifically identify the American Pronghorn. On September 17, 1804, Merriweather Lewis wrote that Pronghorn movements were “…more like the flight of birds than the movement of an earthly being” with “a speed equal to that of the most distinguished race-horse.” Pronghorn are small and graceful. We watched a herd disappear as they fled from predators. Their movements were similar to a flock of birds and they were gone in an instant. This young buck was alert but not threatened so he watched us without concern. The small buds on his head have yet to grow into the heart-shaped set of antlers that are so distinctive of Pronghorn bucks.
