Island Fox Success Story - Pup and Mother Reunited

island fox pup
Island fox recovery is a success story, but sometimes it is nice to focus on individual successes.

This May an island fox pup, only a few days old, was separated from its parents. It was so young, its eyes were still closed. When the pup was found on a dirt road on Catalina Island, it was weak and hungry. Biologists with the Catalina Island Conservancy rallied to the pup's aid. Veterinary care was provided and after two weeks, the pup was healthy enough to be returned. But the clock was ticking on a possible reunion and acceptance from its fox family.

Returning to the area where the pup was found, biologist Lara Brenner and Emily Hamblen captured adult island foxes, including a female who showed signs of lactating. After observing interactions between the pup and the female, the pup was allowed to approach the female and it immediately began nursing. Mom and pup were reunited. The mother fox was radio-collared so that the biologists could locate the family and check in to see how the pup was doing. But getting everyone safely returned to the wild was a challenge. Watch the heart-warming story of mother and pup.



 
Three cheers for a brave island fox pup, a devoted mother fox, and the determined Catalina biologists who facilitated a successful reunion.

Friends of the Island Fox supports the CIC Fox Program with radio collars, fox health measures and "Fox-safer" trash cans. With your help, FIF replaced the electronic elements of traffic speed sign on Catalina in 2018 to help slow down drivers on a section of road dangerous to island foxes.

What Has Arrived at Channel Islands National Park?

 Radio collars!


Five new radio collars
still in the wrapper
and 
Six refurbished radio collars
all rebuilt and ready to go back on island foxes!
...have arrived at Channel Islands National Park. These radio-telemetry collars will be fitted on island foxes in the next few months as biological technicians count island foxes and check their health.

Your donations funded these radio collars!


Look closely, this island fox is wearing a radio collar
Foxes with worn collars will be giving them up for refurbishing or new batteries. You have funded fourteen more of these collars to go from the field to the workshop for refitting. More on Refurbished Radio Collars

Radio collars offer a frontline of defense for monitoring and protecting island foxes.

Fox Foto Friday - What is that fox doing?


You guessed it! She is marking her territory with urine. Island foxes are very territorial. Territory = food resources. Food means she and her mate can support a litter of pups.

Thanks to Daniel for taking this great photo on a trip to Santa Cruz Island with Friends of the Island Fox. Interested in traveling to see island foxes? Subscribe to the FIF newsletter for info on upcoming trips.

Marking territory with urine communicates through scent to other island foxes. Both male and female island foxes mark territory with urine and with scat.

Recycling Island Fox Radio Collars


What can you do with a radio-tracking collar that looks like this?

Recycle it!

Across the Channel Islands, a select number of island foxes wear radio-tracking collars. See more about sentinel foxes. But radio collars have a limited lifespan. Their batteries last up to 36 months, then they need to be replaced. Refitting batteries, however, isn't like put new batteries in a flashlight. The waterproof and fox-proof casing has to be removed and refurbished in a workshop.

Friends of the Island Fox is happy to announce that our February fundraiser more than met our goal to fund the recycling of radio collars for Channel Islands National Park. 

Thanks to your donations 
FIF is refurbishing all 20 of the radio collars 
that CINP planned to recycle in 2018


"The collars will get new antennas, new casings, new batteries, new bands, and/or any other new parts that may be necessary," says Laura Shaskey, Wildlife Biologist at Channel Islands National Park. "They will be completely rebuilt, however intact components will be re-used. As you can see the previously used collars are in very poor shape, chewed up, and are often missing antenna."

Another important benefit of recycling radio collars is the reusing of established bandwidths of radio frequency. In our high-tech wireless world, more and more radio frequencies are being gobbled up for human devices. Fewer radio frequencies are available for wildlife tracking equipment. Recycling collars and reusing pre-established radio-collar frequencies is a smart use of physical and audio resources.


As Shaskey points out, "Refurbishing collars is an efficient cost-effective method to replace collars, so they are as good as new for monitoring another fox for the next three years."


Because recycling a radio collar costs less, FIF was also able to purchase 5 new radio collars for use in Channel Islands National Park.



25 radio tracking collars that will be placed on island foxes 
this season because of your donations!

"Thanks again for all your support with collar purchases this year! It is a great help!" - Laura Shaskey

Fox Foto Friday - An Island Fox Den

courtesy of Will Campbell
Across the Channel Islands, island fox pairs are preparing for parenthood. They've found a protected spot for a den. The den may be between rocks, under tree roots or bushes, or an abandoned burrow dug by another animal. It just needs to be protected and out of the weather. This den is where their pups will be born.

Island fox pups are typically born in April. Most litters have 2-3 pups. The rain this year has been below average so litter size may tend to be smaller. 

Less rain = fewer resources. 
Fewer resources = fewer island fox pups.

More Connections Between Bald Eagles and Island Foxes

The recovery of bald eagles on the California Channel Islands has played an important role in island fox recovery. Bald eagles prey on fish and marine birds. They are not mammal predators and do not actively hunt island foxes. Because bald eagles nest on the Channel Islands, they chase away migrating golden eagles and do not allow them to colonize the islands.

With 50-60 bald eagles now living across the eight Channel Islands, no island foxes are known to have been killed by golden eagles for several years. Bald eagles definitely make a difference in the ecosystem for island foxes. But what benefit do island foxes provide bald eagles?  

Across the Channel Islands bald eagles are hatching out their 2018 chicks. Channel Island National Park reported that there are 13 active bald eagle nests across the islands this year and at least 22 known eggs.  

courtesy P. Sharpe
Three eaglets hatched in the Sauces Canyon nest last week on Santa Cruz Island. You can watch them 24 hrs a day via a webcam https://explore.org/livecams/bald-eagles/channel-islands-national-park-sauces-bald-eagle

Tonight, close observers saw some unexpected visitors to the bald eagle nest. Along with fish, the parent bald eagles have brought scavenged seal placenta back to the nest to feed their chicks. But with the darkness, something else stole up into the nest to eat the placenta bits. Circled in green, do you see the surprise scavengers? island deer mice.


captured image from the webcam 3/20/18
Who would have thought that hungry deer mice would come up into the bald eagle nest to eat meaty placenta. The eagle does not have night vision, it is a daytime hunter. It could hear the munching mice and would occasionally drive them off. Island deer mice are known to eat songbird eggs, and possibly chicks, when given the opportunity, (like when island fox populations were very low). The eaglets are small and without their parent's protection, would they be prey for the gang of deer mice? At one point six deer mice were visible.

Island foxes play an important role in controlling island deer mouse populations. 

Other bald eagle parents on the islands are sleeping soundly tonight, but the bald eagle with the messy nest is wide awake in the rain. It has two jobs tonight: keeping three eaglets warm and dry, and keeping the deer mice at bay. It will be a long night for this bald eagle, it needs an island fox.

Island foxes sometimes clean leftover food out of bald eagle nests. Island fox in a bald eagle nest.

Sex and the Single Island Fox

When it comes to reproduction, island foxes are not your typical canine. 

A female dog will go into heat and become reproductively receptive even if there is no male dog nearby. Dogs have spontaneous ovulation, they have a determined reproductive cycle which includes a spike of hormone to release the ovum or egg into the female's reproductive tract. Not so with island foxes. 

Captive breeding occurred from 2000 - 2008
During the period of captive breeding to increase island fox populations, it was discovered that female island foxes, without access to a male partner, did not show the elevated hormone patterns signaling they had ovulated. These single females did not go into heat.

A similar reproductive behavior occurs in members of suborder Feliformia, or the cat branch of carnivores (cats, otters, wolverines, ferrets, etc.), and in bears. These species have induced ovulation–some physical or hormonal stimulus from the male is required to stimulate or initiate ovulation.

To date island foxes are the only canine observed to have this reproductive trait. However, research on this facet of reproduction is minimal. It is unknown if gray foxes, the ancestor of island foxes, are induced ovulators. 

Gray foxes (Urocyon cinereoargenteus) are an ancient species. Some sources consider them the most basal or closest to the root of the canine family tree. In Decline and Recovery of the Island Fox the authors suggest induced ovulation may be a primitive trait shared between these ancient canines and other carnivores, like cats and bears. Spontaneous ovulation may have evolved later in the branches of the canine family tree that gave rise to red foxes and wolves. Compare gray fox and island fox.

The single female island fox? 

Well, she just doesn't waste her reproductive energy if there is no eligible mate at hand. 

What other animals are known to have induced ovulation? rabbits and camels

Fox Foto Friday - Island Foxes in Art

To know island foxes is to love them. This charming wedding cake duo topped the nuptial cake for one of our favorite island fox biologists. 


From cakes to wood carvings, ...


...island foxes are gradually making their way into culture and consciousness.

If you think about it, island foxes are a pretty good totem for marital happiness: they are more monogamous than humans and form very strong pair bonds. Males and females are devoted to family. More about island fox behavior.

Fox Foto Friday - Island Fox Eating Redberry


Island foxes love their native fruit! Across the Channel Islands native fruit sometimes makes up over 50% of the island fox's diet

Researcher Todd West observed this island fox eating island redberry. From toyon and lemonade berry, to Catalina Island cherry and prickly pear cactus, if the native fruit is red, island foxes eat it.

Thank you, Todd, for sharing your photo with Friends of the Island Fox. More of Todd's photos. More island foxes eating.

Make the Island Fox Your Sweetheart

This Valentine's Day
Won't you share your passion?

February through April, island fox pups will be born across the Channel Islands. Help give the 2018 pups the best chance of survival by supporting two important conservation projects.

Recycled radio-tracking collars: 
Good for foxes and the environment
Pups on San Miguel Island face serious challenges like drought and climate change. Young foxes are struggling to survive and adults are threatened by new parasites.


island fox with radio collar
You can help National Park biologists better protect the foxes by donating toward a radio-tracking collar. Radio collars help biologists respond quickly when foxes are in danger. By refurbishing previously used collars, we're also reducing costs for foxes and the environment. Each refurbished collar costs $220, a 33% savings over typical radio collar costs and keeps a used collar out of landfills.

This Valentine's Day, FIF has our hearts set on funding 15 radio collars!


Slow Down for Foxes!

Island foxes on Catalina face another serious danger: automobiles. One of the ways to alert drivers to the dangers of speeding in fox territory is through electronic signs that tell drivers they are going too fast. These signs have been shown to slow down traffic and reduce fox injuries and death.

A critical sign on Catalina needs replacing. For $3,000, we can repair the sign and put it back in service, saving more fox lives.

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.

courtesy of Douglas E. Welch
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. -
Douglas Welch

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.

This island fox is eating small native berries. 
Plants sustain island foxes.

2018 begins with some exciting news!

Friends of the Island Fox 
is now a program of Channel Islands Restoration.

https://cirweb.org/

Channel Islands Restoration (CIR) is a 501(c)(3) nonprofit organization that protects rare and endangered plants and animals by restoring habitat in sensitive and unique natural areas on the California Channel Islands and adjacent mainland.  

In 2016, FIF and CIR worked together taking two groups of volunteers to Santa Cruz Island to remove invasive plants.

Families removing invasive oyster plant on Santa Cruz Island


Island foxes are intricately connected to the other plants and animals in their ecosystem. This new relationship with CIR will enhance FIF's ability to effect long-term positive change for island foxes across the six islands where they live.  We look forward to working with CIR to revitalize habitat for island foxes and other island species. 

The health and welfare of island foxes remains FIF's priority. From radio-tracking collars to vaccinations, from campground food lockers to education presentations, your donations to Friends of the Island Fox support a variety of conservation efforts, public education, and research focused on island fox survival. What We Do

Meet FIF's new Advisory Committee and consider how you can help island foxes. 

Working together we can protect island foxes and their Channel Island home.
