This past year, in 2013, three radio-collared island foxes were killed by golden eagle predation. Two foxes were killed by a golden eagle on San Miguel Island and one on Santa Cruz Island. Biologists do not know if the island foxes were killed by the same golden eagle or by two different golden eagles. The distance between the islands can be easily managed by a single large eagle. However, in the past, golden eagles have often preyed on island foxes in a specific area when they have been successful.
As the populations of island foxes have increased, the cost of radio-collaring all adults has become prohibitive. Radio-tracking collars now cost $300 each. A representative number of island foxes are radio-collared on each island–approximately 5% to 11% of individual island foxes on each of the northern islands.

Because radio-tracking collars give off a specific signal when a fox is no longer living, radio collars are vital tools for locating individual island foxes and responding quickly to determine why that animal has died. Island Fox CSI
On Santa Catalina Island this past year biologists were on the look out for stowaway raccoons carrying disease. But in 2013 they encountered a new invader–a northern opossum that hitchhiked on a private boat and made its way onto the island. Introduced animals pose a serious disease threat to island foxes. Canine distemper
Radio-tracking collars are the island foxes' best defense against unexpected threats. To-date Friends of the Island Fox supporters have funded 96 radio collars.
