Pronghorns are interesting animals! They eat cactus, straight up, even with all those spines -- but they really like flowers, too. I was fortunate to count pronghorns across western Kansas years ago. We used a small 4-seater plane, with a pilot and one person each to focus on counting the males, females, and young ones. We flew a giant back-and-forth pattern, starting along the Colorado border. Our counting started right at sunrise, when the low sun would shine off the bright white rear-ends of the pronghorns. When we saw a herd, the pilot would dive, hard, and we would count as the animals scattered. Then he would pull up and continue on. He buzzed a few pheasant, too. I didn't get airsick until we stopped mid-morning for breakfast -- those greasy airport restaurant eggs slid right down, and then slid right back up on the next dive into another pronghorn herd. The view of all those pronghorns, running with their bright butts reflecting the early morning sun, was worth it, though!
