Pronghorn antelope are fascinating. They are strictly North American animals; they really have no relatives anywhere else in the world. They are the fastest mammals in North America and the second fastest in the world, after the cheetah. They can run just hours after they are born. Pronghorn have larger eyes than any other animal their size so they can detect predators many miles away. Young ones are easy prey for coyotes, wolves, golden eagles and people, of course, but the adults can basically outrun everything. They stay in an area where they can see for miles around and outrun anything coming after them. In this scene, they’re all running really fast and you don’t know why. You can’t see any predators in the painting but perhaps there’s one on the other side of the hill; who knows? It’s a mystery.
