Video of Wild Island Fox

What is small, but mighty? Only 3-6 lbs., but willing to stand its ground and protect its territory? An island fox.

Catalina Island Conservancy wildlife biologist Calvin Duncan approached a wild fox’s territory, he took this video of an island fox on Santa Catalina Island.

Protecting territory is important for a pair of island foxes. They need a hunting area that will provide enough food to support themselves and their pups. How does an island fox let you know you are in its territory? Watch and see.




Images like this of an island fox in the wild are very rare. Island foxes on Santa Catalina Island declined dramatically between 1998 and 2000 because of a disease, canine distemper, that was passed to them from a domestic dog. Today the estimated population has increased to approximately 572 individuals, slightly more than one third of their original number. Catalina island fox decline

The fact that island foxes are running wild again on Catalina, Santa Rosa, Santa Cruz, and San Miguel Islands is due to the undaunted efforts of biologists, scientists, government agencies, private conservation organizations and concerned individuals like YOU.

When you support island fox conservation efforts YOU HELP to make sure that moments like this will continue into the future.

A special thanks to the Catalina Island Conservancy fox biologists Calvin Duncan and Julie King for sharing their experiences in the field with us. For more on their work with the Catalina island fox: Counting island foxes; Island Fox Health Check.

Island Fox Health Checks on Catalina Island

The Santa Catalina Island fox became endangered when an outbreak of disease, believed to be canine distemper, killed over 85% of the population in just a few years. To help prevent such catastrophic events in the future, biologists across the Channel Islands use the late summer and early fall to count island foxes and give them health checks.

In September, Friends of the Island Fox went out in the field with Julie King, fox biologist for the Catalina Island Conservancy as she did health checks on wild island foxes.

An island fox health check involves:

• taking the weight - The island fox is weighed while still in the trap.
• evaluation of over all physical status - The biologist feels the fox’s body for any lumps, bumps or wounds. (photo above)

• visual check of teeth, coat - Teeth are checked for wear and breakage (this female fox was under 2 years old but had a broken tip on an upper canine tooth); the coat is examined for overall heath and the presence of parasites, fleas and ticks.
• ear exam - An otoscope is used to look in the fox’s ears. The biologist is looking for ear mites, inflammation and disease.

• vaccinations - Island foxes receive vaccinations to help reduce the chance of disease.

• drawing a blood sample - The blood sample provides additional information on health and possible disease exposure. A mask is put over the foxes eyes to reduce the animal's stress while being handled by humans.

How was the island fox caught for the health check?

The island foxes on Santa Catalina are increasing in number, but a new threat is causing them problems, ear mites. Cancerous tumors are forming in the ears of island foxes on Catalina. The relationship between the ear mites and the cancer is currently being studied. Friends of the Island Fox would like to help the Catalina Island Conservancy in their quest to solve this mystery that is posing a new danger to island foxes. You can help by making a donation through the "Pay Pal" or "Donate Now" buttons at the top right of the page.

Through generous donations Friends of the Island Fox has funded 17 radio collars in the past 2 years so island foxes can be monitored in the wild. Your donation to Friends of the Island Fox helps fund conservation efforts across all of the Channel Islands to help save the island fox.

Counting Island Foxes

If you are a fox biologist on the Channel Islands, late summer through early autumn is a busy season. During this short window of time, island fox populations are counted and individual animals receive health check-ups. To get their hands on these pint-sized, but sharp-toothed predators, special box-type traps are put out in specific areas.

In September, Friends of the Island Fox rode along with Julie King, fox biologist for the Catalina Island Conservancy. The day on Santa Catalina Island started very early, because all of the traps on a string must be checked before the day starts to get warm.

Most foxes are captured in the evening or during the night. Even so, the traps are set in shaded spots so that a fox won’t become overheated. Each trap has a covering over the top and grass or hay inside to make it more comfortable

The fox is first identified by its “pit tag.” A scanner responds to the microchip tag and displays the animals identification number.

Endangered island foxes on Santa Catalina, San Miguel, Santa Rosa and Santa Cruz islands are given microchip identification tags like those you would use on your pet dog. The fox in the trap is scanned with the microchip reader to identify it. In this way, the biologist knows when the fox was last caught and whether or not it needs vaccinations, a health check or radio collar maintenance.

If the fox does not have a microchip or pit tag, it will receive one.

If it has already been caught this season and has had its health check, the biologist will release the fox and reset the trap. If not, then the island fox will spend 15-20 minutes with the biologist getting a full health workup.

Fire Foxes - Catalina Island Fox Update

Early reports on island foxes surviving the Catalina Island fire are very hopeful.

Ann Muscat of the Catalina Island Conservancy

“Habitat damage is extensive and will require further analysis. There is no obvious loss of larger wildlife (eagle chicks in nest, deer, bison, foxes). Our staff was able to fly over the Island and monitor for 48 radio-collared foxes and all signals were picked up. This is very good news. Foxes are in the pupping season, however, and staff are now surveying the burn area for females in their dens to see if pups are surviving. A number of iron wood and oak groves were lost, but until we can overlay our vegetation maps onto the fire area, we will not know the full extent of the loss of rare and endangered plant species.”

Julie King, Senior Wildlife Biologist, Catalina Island Conservancy adds the following fox details about four foxes that were sighted in the burn area. Three were non-injured, but one female fox with “severe burns to all four paws, severe dehydration and malnutrition” was captured. The “fox is being treated in the Middle Ranch Veterinary Clinic under the direction of Institute for Wildlife Studies veterinarian Dr. Winston Vickers. An additional fox was captured in the process, a large healthy male, was given a workup, fitted with a radio collar and released at the location of capture.”

As of Saturday, May 26, 2007:

We'll be setting traps all weekend to get a better assessment of potential injuries in the burn area. I'll be sure to keep you updated if we get any additional injuries. On a happy note, the fox we are treating is responding very well to treatment. When caught, she was only 1.2kg and she's now up to 1.7kg. She's eating well and so far there is no sign of infection in her paws. It has only been 5 days, but her feet do appear to be slowly healing. She has a long road ahead of her, but she's doing much better than we had initially expected. Dr. Vickers will be out on June 4th to do an assessment. - Julie King

As the information from the Catalina fire area becomes available we will post it here. Friends of the Island Fox is rallying our resources to see what we can do to help the Catalina island foxes. These island fox survivors of the fire need our support more than ever.

Fire and Foxes on Catalina Island - Update

Just a quick Update on the island foxes on Santa Catalina Island.

Friends of the Island Fox has been in communication with the Catalina Island Conservancy (CIC). The few individual island foxes that are in captive care for health problems and Tachi, CIC's education fox, are all fine. (For more about Tachi)

As of Thursday May 17, the fire is completely out. Now biologists are beginning the task of trying to locate radio collared island foxes to determine if there were any fatalities due to the fire.

CIC will make their full report at the Fox Conference in mid June. A complete summary of all island fox conservation successes and issues will be posted here following the Conference. (most recent look at island foxes on Santa Catalina Island)

Thank you for your concern about the island foxes in the face of this recent fire threat.

Fire and Foxes on Catalina Island

As of 6 PM Friday May 11 the wildfire on Catalina Island appears to be 35% contained. The current situation is an unfortunate example of the delicate nature of island habitats.

Officials from the Catalina Island Conservancy report:

Bald Eagles
The bald eagle chicks that recently hatched on the island are safe. The nests are on the eastern end of the island and not near the fire area. (more on the new bald eagle chicks)

Island Foxes
Currently the effect of the fire on wild island foxes is unknown. Radio collars on individual foxes will be vital in locating individual animals and determining if any have been overwhelmed by the wildfire.

This is another situation that highlights the importance of radio collars on the endangered island foxes on San Miguel, Santa Rosa, Santa Cruz and Santa Catalina Islands. Island foxes are currently having their pups on the islands. This new generation will soon need radio collars.

You can help make sure all endangered island foxes have radio collars.
