Island Fox

This will be the last post about foxes we are ending with the Island Fox.

The Island fox is native to six of the eight Channel Islands in California it is considered critically endangered by the IUCN, it is threaten by golden eagles, disease, and habitat destruction.

The Catalina Island Conservancy and Institute for Wildlife Studies have established a fox recovery program for the island fox. This program includes vaccination, relocation, and captive breeding. 

The island fox is a small fox species that is endemic to six of the eight Channel Islands of California. There are six subspecies, each unique to the island it lives on, reflecting its evolutionary history. They are generally docile, show little fear of humans, and are easily tamed.

The island fox has similar markings to the gray fox. They have gray colouring on the back, rust colouring on the sides, and white underneath. The face has a distinctive black, white, and rufous-coloured patterns.

In March 2004, four subspecies of the island fox were classified as a federally protected endangered species: the Santa Cruz Island fox, Santa Rosa Island fox, San Miguel Island fox and the Santa Catalina Island fox.

Island foxes reach sexual maturity at 10 months, and females usually breed within the first year. These foxes can live for up to 10 years in the wild, but four to six years is more typical.

They are generally docile, show little fear of humans, and are easily tamed. Island foxes played an important role in the spiritual lives of native Channel Islanders. They have been likely semi-domesticated as pets, used as pelts, or for other functions, like pest control.

They are omnivorous, eating both plants and other animals. They eat a large amount of insects, some island deer mice, reptiles, and fruit from native plants. New evidence is showing marine resources may be important for island foxes. Their diet also changes with the seasons.

 The primary threat to the island fox is predation by invasive golden eagles. The species is also very vulnerable to canine distemper transmitted by domestic dogs, habitat fragmentation due to development, and habitat loss to introduced livestock and game species.
