雅思阅读精选：加州小狐狸的"绝处逢生"

　　Sleepy Juice and Robo-Dogs

　　The crisis spurred a recovery effort by the NPS and the Nature Conservancy, which owns 76 percent of Santa Cruz Island. We went to the wall on the island foxes, Coonan said. In the park services, were mandated to save everything entrusted to our stewardship. If we let the island foxes go extinct, we might as well not be here managing anything.

　　Captive-breeding programs were established on Santa Cruz, Santa Rosa, and San Miguel islands. Contract hunters were brought in to remove the non-native feral pigs and sheep, which had stripped the islands of vegetative cover for the foxes.

　　And bald eagleswhich feed mainly on fish and dont affect the foxeswere slowly reestablished on the islands while golden eagles were captured and released back on the mainland.

　　That last task proved especially challenging. The last golden eagle pair was really tricky to get because they had seen all their buddies get captured, said the Nature Conservancys Boser.

　　After increasingly creative attempts to catch the birdsincluding using a fake egg filled with a sedative that Boser called sleepy juice, and a robotic dog dressed up to look like a fox, the final golden eagle pair was netted by helicopters in 2006. In total, 44 golden eagles were removed from the islands.
