The CDU decided to head into the brush itself. It bushwhacked its way to South Africa, where it caught up with Kruger National Park veterinarian Roy Bengis, who has worked for 22 years tending the park's baboons, buffalo, leopards, lions, rhinos, and other animals large and small. Otherwise, they're pretty hard to miss. Fresh elephant dung has a very strong odor. That's an odor you absolutely can't miss, even from 200 or 300 meters away.
Lions have a pungent predator odor.
What appeared to be an enormous grizzly roused itself and raised its head. The CDU had crossed two continents and an ocean to find Peacock, who lives on the edge of Yellowstone Park in Livingston, Montana. The guy backpacking in the Rockies probably didn't see the grizzly because he wasn't familiar with the territory. Grizzlies leave distinct tracks, and they leave big old caviar pies if they've been eating huckleberries. They're pretty visible, and they're easy prey for humans.
