The night the last golden eagles were captured, Boser and her colleagues celebrated atop a mountain on Santa Cruz Island. A collective cheer echoed across the Santa Barbara Channel, Boser said.

　　Swift Recovery

　　With the feral pigs and the golden eagles gone, the fox population reboundedand with a swiftness that stunned even the scientists and conservationists involved.

　　Today there are about 1,300 foxes on Santa Cruz Island, 500 on San Miguel Island, and 600 on Santa Rosa Island, with each population having a 90 percent annual survival rate.

　　Its a strange thing, Coonan said. The official recovery plan has not even been finalized , and yet these populations are doing so well that they can come off the endangered species list.

　　Brian Hudgens, a research ecologist at the Institute for Wildlife Studies, which ran the fox captive-breeding program, agreed that some of island fox subspecies are just about ready for delisting.

　　For the subspecies on San Miguel and Santa Cruz, their populations are large enough and they are doing well enough that they are no longer in danger, Hudgens said. Santa Rosa is almost there. Itll probably take a couple more years.

　　The work to save the island fox is far from over, however. The Nature Conservancy and the NPS continue to monitor the foxes, keeping an eye out for dangers like pathogens and parasites, as well as looming threats such as climate change.
