Island foxes are heavily preyed on by golden eagles, which had a very small food source after the island's feral pig population was exterminated. Disease also takes a toll on the island fox population because they have no immunity to parasites or other health issues due to their isolation. When humans or other animals enter the island, they may carry with them strains of diseases that are foreign to the foxes and they have no defense against it. Also, diminished food supply and loss of habitat caused by introduced species on the island also increase the foxes chance of extinction.
