The golden eagle is a large, dark brown raptor with broad wings. In Channel Islands National Park, predation by the golden eagle on the endemic island fox brought the latter close to extinction, with golden eagle breeding on the islands supported by feral pigs on Santa Cruz Island and deer on Santa Rosa Island Other important prey include birds; indeed,virtually any bird, from jays to swans, are potential prey. In June 2007, the bird's recovery prompted its removal from the Endangered Species list. They may be at the fourth or fifth trophic level.
