They faced a sharp decrease in number in the late 1990s. Populations of the fox had dropped more than 90 percent on four of the six islands. On Santa Cruz Island, where 1,400 foxes had once lived, fewer than 55 remained. The population on Santa Rosa Island had dropped from 1,780 to just 15.“Golden eagles were the main threat (威胁) facing the small animals，” scientists said. The birds were not native to the islands and had only started frequenting the area in the 1990s after use of the pesticide (农药) DDT wiped out the larger, native bald eagles. “Golden eagle predation (捕食行为) was considered unnatural because golden eagles were rarely observed，” the National Park Service explained on its website. “With the golden eagles sharp talons, swiftness of flight, and four times the body mass of a fox, they easily hunted the fox.”The Channel Islands fox was added to the endangered species list in 2004 a move that led to an enormous effort to save the animal from dying out.Empowered by the Endangered Species Act, at least 300 scientists and conservation (保护) experts, and nonprofit organizations joined forces to start conservation measures, including golden eagle relocation programs.
