Restricted to 6 islands off the coast of California. This species is closely related to the mainland version (they are in the same genus), though each of the six islands have a slightly different island fox. While each island fox can interbreed, each have very different characteristics.
They are smaller than the mainland fox, and are easily tamed – they also have little natural fear of humans. It is thought that the foxes have been on the islands for at least 9000 years.
Given the small size of these islands, there are never going to be huge populations. Humans are also going to do regular things that might effect these numbers. It is thought that a recent drop in numbers followed the reduction in feral pigs, which meant that golden eagles switched from eating these pigs to foxes
