Birds are widespread and respond quickly to changes in the environment. 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. The extinction of the passenger pigeon is connected to the proliferation of Lyme disease. Schwemm, eds., Proceedings of the Sixth California Islands Symposium.
