Island Foxes Are Getting New Radio Collars

 

Six new radio collars funded by Friends of the Island Fox will arrive on Catalina Island next week!

Across the Channel Islands, island foxes are receiving annual health checks and new radio-tracking collars.

 

Watch the video below of M173. He is a four-year-old male on Santa Rosa Island and his radio collar was replaced last week during his health check.

He is not tranquilized. The green hood covers his eyes and keeps his mouth closed. This keeps him calm and enables biologists to quickly complete a health check, vaccinate the fox against canine distemper and rabies, and for some island foxes, deploy a new or refurbished radio collar.

This radio collar will send signals to biologists for the next 2–3 years. The signal will help locate M173 and the type of signal informs the biologist if he is moving around normally or if something might have happened to him. In the case of a mortality signal, biologists can follow the signal to find the island fox's body and determine what happened. If there is a threat to other island foxes, action can be taken quickly.

For the 2023 health check season Friends of the Island Fox has supplied:

• 5 new and 15 refurbished radio collars to Santa Cruz Island
• 24 refurbished radio collar to San Miguel and Santa Rosa Islands
• 6 new radio collars to Catalina Island 

Radio collars offer the best way to monitor island fox survival 

in the wild. 

Your donations make it all possible.

Island Foxes With a Sweet Tooth

What is that island fox doing?

On a December trip to Santa Cruz Island several observers documented a number of island foxes busily searching the ground under the eucalyptus trees.

Initially we thought they were finding food debris left by campers, but the more we watched the more it became apparent that the island foxes were licking something on the leaf litter. The December day was unusually warm and dry. (This was while the Thomas Fire in Ventura was blazing.) We watched foxes in close proximity to each other completely engaged in their search and paying no attention to us or each other. At one point there were seven foxes in this small area. -

bloom after island fox licked it

The red gum eucalyptus trees were in bloom. One young island fox stood on its hind legs and pulled down a low branch so it could access the flowers. One at a time, it stuck it's muzzle into the eucalyptus blooms, licking and nibbling them. I've been visiting Santa Cruz for over 10 years. I've never seen this behavior before. - Keri Dearborn 

Little beads of sticky sap were on the tables and benches. I touched my finger to the sap and tapped it on my tongue–it was sweet.  - Michael Lawshe

One island fox wandered within several feet of me. Each time it found a drop of sweet sap, it would lick it up and make a soft sound, almost like a purr. - Keri Dearborn
 
On this dry hot day in December, the island foxes were licking up the sweet eucalyptus sap. While this is not known to be a typical behavior, it is another example of the adaptive nature of these unique canines. Typical island fox diet. Island foxes eating toyon berries that same day.

Visiting The Channel Island Fox

Santa Cruz Island fox (Urocyon littoralis santacruzae)

Summer is a great time to visit California's Channel Island fox.

May 3, 2014 - Friends of the Island Fox led a trip to Scorpion Anchorage on Santa Cruz Island in Channel Islands National Park. 

The day began with a visit to the National Park Headquarters in Ventura and a tour of the Visitor Center.  As well as the island fox, Santa Cruz is home to numerous endemic plants and animals (species found only on the Channel Islands, like the island scrub jay)

Much of the water surrounding the Channel Islands is also protected by the Channel Islands Marine Sanctuary. Kelp forests surrounding the islands provide food and shelter for a variety of marine species. Ranger Tina provided an in depth talk on tide pool creatures.

The island received six inches of rain in early April which helped to make the island green and the wildflowers bountiful.

Island foxes were also abundant. Our first island fox of the day was spotted within minutes of arriving on the island. Over the course of the day, groups saw up to 10 individual island foxes.

This trip we observed interesting interactions between island foxes:

One older individual, climbing up the hillside leaving the campground, area became alert and defensive when another fox began following it. The older fox arched its tail, making itself appear larger, and defensively turned around to face its follower. However the island fox following the older individual was smaller and appeared younger, more spry. When the smaller fox reached the defensive fox, it immediately displayed submissive behavior–licking under the chin of the older fox. The older fox relaxed. There seemed to be recognition between the two individuals. It looked somewhat like a pup with a parent, but both of these island foxes were definitely adults. It is possible that the smaller fox was either an adult offspring from another year or a female approaching a male, not her mate. The two island foxes walked side-by-side for a couple of yards along the hillside. (see video above) Then the older fox continued on its way out of the campground area. The younger fox, turned around and back tracked along the path she had just walked and went the other direction. 

In another situation, two healthy adult island foxes coming from opposite directions toward the stream bed at the edge of the campground, specifically avoided each other. They passed within ten feet of each other and actively avoided an encounter. One of these island foxes was wearing a radio collar.

Seeing multiple encounters between individuals is an exciting demonstration of the successful return of this endangered species.  (More about island foxes)

You can visit three of the islands where island foxes live: Santa Cruz and Santa Rosa Islands, in the Channel Islands National Park, and Santa Catalina Island. Each island has its own unique traits and treasures, but they all have Channel Island foxes.

Island foxes have a long relationship with humans. We can all help that relationship continue long into the future by participating in conservation efforts to protect this species and by respecting these wild animals when we visit their only home in the whole world. 

What Does The Fox Say?

Since a music video with singers dressed as foxes went viral, the refrain "What does the fox say?" has become a recurring question.

Well we have an answer. The island fox BARKS!

Watch the video below taken in the field by biologist Calvin Duncan on Santa Catalina Island.

Island foxes bark to declare their territory. They may be small in size, but Channel Island foxes are big in personality.

Now you know what the fox REALLY says.
