"From the cockpit of a Cessna airplane, Gary Mowad, a special agent for the U.S. Fish and Wildlife Service, spotted what looked like a dried-out pond in rural eastern Colorado. The banks of the pond were black, so he suspected it was actually a pit for oil company waste.

When he drove out to inspect the half-acre pond, he found something far worse. As he expected, its banks were covered with dried oil. But it was the bottom of the abandoned pit that shocked him: It was blanketed with the bones of thousands of birds.

“You see that carnage and you know there are 500 more pits with oil on them and you can’t see the bottom,” Mowad said. “It’s an ‘Oh, my God’ moment. If there are this many dead birds in this pit, can you imagine what’s in the others?”"
