FIF Funds 500 Microchips for Island Fox Identification

We started with a goal of 250 microchips and with your help 

we funded 500!

That means 500 young island foxes captured during annual counting this fall will receive microchips that will identify those individual animals for the rest of their lives.

Why are microchips so important to the conservation of the endangered island fox?

Calvin Duncan, Wildlife Biologist for the Catalina Island Conservancy, explains:

By scanning each microchip while the fox is still in the trap and checking the data we can limit the amount of time, or occurrences, that an animal is handled by humans by immediately releasing foxes that have already been captured that year. They [microchips] also support our ability to make sure each fox receives the necessary vaccines and in the proper doses. Proper identification of each fox is probably the most important aspect of our recovery and research efforts.

Microchips provide information across the life of an individual island fox, like “Burnie Boots.” Burnie’s Story

Because individual animals can be quickly identified, we now understand that male island fox pups tend to disperse as far as possible from their parents’ territory, while females tend to stay near by. On Catalina Island there is a small isthmus between the large part of the island and a small area to the northwest. Few island foxes venture across the isthmus and it was thought they were males dispersing to find territory. However, a microchip helped researchers identify a trailblazing female that also made the journey. 

How does a passive identification tag or microchip work?

Each microchip costs $10 but the investment in island fox conservation is priceless.

Coastal Clean-up Day 2013 and the Island Fox

Help make a difference for local wildlife, including the Channel Island fox.

Friends of the Island Fox and the Channel Island Park Foundation invite you to join us for:

Coastal Clean-up Day 2013

at

Ventura Harbor Cove Beach

Saturday, Sept. 21

9am-12pm

Trash in our local waterways and ocean can be life threatening to wildlife. One of our friends took this photo of a female sea lion on the Channel Islands. If you look at the female laying along the bottom of the photo, you can see some kind of man-made debris wrapped around the animal’s neck and cutting into her flesh. 

Island foxes searching for food at the water’s edge can also be injured by items that wash up on beaches. Find out about the island fox and the fishing lure

What might seem like benign trash can be dangerous to small animals. Last year a young island fox got its head caught in a small potato chip bag. In its panic to remove the bag, the island fox ended up in the surf and drown.

Some trash can even look like natural items on the beach. See items we found on the beach in June on Santa Cruz Island. 

Help Clean-up the Beach and keep wildlife and people safe.

Volunteers can register the morning of Coastal Clean-up Day at either the Channel Island National Park Visitor Center or the east end of Spinnaker Drive (Surfer’s Knoll).

If possible, please bring your own buckets and gloves.  Participants will be given data cards to record the trash they pick up. (Minors must have a parent sign a waiver for them to participate.)

A MicroChip Tells the Story of a Special Island Fox

Burnie Boots in 2008; courtesy CIC

This island fox was born in 2006 and captured as a juvenile her first autumn. She was only six months old when she received her first health check and an identification microchip. A tiny passive electronic identification tag was placed under her skin, between her shoulders. For the rest of her life, biologists would be able to identify her as an individual.

In May of 2007, a human-ignited fire swept over a large swath of Catalina Island. It just happened that our little female island fox had been living in the area that went up in flames. She was the only island fox found severely injured in the 2007 fire. Her fur was singed and her feet were badly burned. The injury to her feet led to the name: “Burnie Boots.”

In the days immediately following the fire the fox had become dehydrated and malnourished because of her injuries. Over the course of several weeks she was nursed back to health at the Catalina Island Conservancy Foxpital.

Before her release back into the wild, Burnie Boots was fitted with a radio collar funded through Friends of the Island Fox and our first Fox Ambassador School–the girls of Westridge School in Pasadena. The radio collar enabled biologists to follow the little female fox’s movements in the wild and in the fall she was recaptured and found to be fully recovered.

In 2008, at age two and a half, Burnie was captured in the fall island-fox count. Her microchip identified her even though she had few physical signs of her earlier injuries. During her health check biologists recorded that she showed signs of having nursed pups. Conservation efforts had made a difference! Burnie Boots survived because of health treatment. She was tracked with a radio collar and now had successfully helped to increase the population of endangered island foxes on Catalina.

Burnie Boots lived a completely wild life for the next year. When she was recaptured in the fall of 2009, she was in good health and weighed 4.6 lbs. The battery on her radio collar was low and she was doing well. The radio collar was removed.

For the next three seasons, Burnie Boots avoided the fall capture, but she continued to be part of the growing island fox population on Catalina Island.

Then, unexpectedly in June of 2013, the body of a female fox was found by the side of the road near Canyon Lodge in Avalon. The microchip reader quickly read the animal’s microchip and identified her as Burnie Boots. Her injuries suggested that she had been hit by a car. Watch for Foxes signs

At seven years of age, Burnie Boots’ individual story has come to an end. But because of her microchip we know she spent all of her life in a fairly small territory in a canyon behind the town of Avalon. Even after the fire, she stayed in that territory and raised pups in the area. Though she was an aging female, there was evidence Burnie had nursed a litter of pups this year. So while her individual story has ended, Burnie lives on in the DNA she has passed on to several litters of pups. This fall maybe her pups will receive ID microchips and start stories of their own.

Microchips help biologists to better understand island fox behavior. You can play a vital role in helping to save endangered island foxes.

Island Fox Summer Puzzle

The story of the island fox is all around you on the Channel Islands. Below is a collection of items found along the beach and trails of Santa Cruz Island during a Friends of the Island Fox's trip to see the island fox. Can you identify these items?

Island foxes do not swim in the ocean, but they will scavenge dead animals that wash ashore. Can you find the kelp crab carapace, mussel and two different clam shells, and remnants of a harbor seal (vertebra and half of a pelvis bone)?

DDT impacted bald eagles living on the Channel Islands. Their extinction led to a change in the natural balance which ultimately threatened island foxes. The brown pelican was also impacted by DDT in the marine environment. Fortunately, the brown pelican population has recovered because of conservation measures.  Find two hollow pelican bones. Native peoples used these bones to make flute-like instruments.

Native people have intermittently lived on the Channel Islands for over 12,000 years. The Chumash people have had a long and valued relationship with the island fox. Another island resource they valued was soapstone. Find this soft, colorful stone that was carved into a variety of items. 

Island foxes do not typically eat sea urchins, moon snails or wavy turban snails. However, these kelp forest creatures depend on a healthy island ecosystem to minimize erosion that would dump silt into the clear water surrounding the islands. This tidal area is a vital habitat for sunlight-dependent kelp forests. The island fox helps reduce island erosion by being the largest seed disperser for the island's fruiting plants. Find these sea creatures that need the island fox: three sea urchins, one moon snail and two wavy turban snails.

While the hard shell-like tunnels of the calcerous tube worm might smell interesting to an island fox, these worms live in the ocean filtering small particles of food from the water. They build their tunnels on tidal rocks and frequently on man-made docks. Find the two structures made by calcerous tube worms.

Since the mid-1800s, people have had a big impact on the Santa Cruz Island ecosystem. Find all of the items related to modern people: eucalyptus (introduced plant), concrete (from buildings), lower limb bone (canon bone) of an ungulate (sheep, goat or pig, all introduced animals), jaw bone of a pig, and a piece of molded fiberglass. 

Answers below:

• kelp crab (1), mussel and two different clam shells (10), and remnants of a harbor seal (5)
• two hollow pelican bones (8)
• colorful soapstone (9) 
• three sea urchins (2), one moon snail (13) and two wavy turban snails (12) 
• calcerous tube worms (14) 
•  eucalyptus (3), concrete tumbled in the ocean (11), lower limb bone of a sheep, goat or pig (6), jaw bone of a pig (7), a piece of molded fiberglass (4)

Radio Collar Milestone !

This summer:

Friends of the Island Fox 

funded its  

90th radio tracking collar

for island foxes  !

Tracking collars, like the one slightly visible on the picture at the left, are worn by island foxes across the four islands where they are considered endangered: San Miguel, Santa Rosa, Santa Cruz and Santa Catalina Islands. (Look for the brown of the collar just below the fox's white cheek patch and the antennae rising up behind its ear and going over its back.) Why are radio collars important?

This rare species of fox is found only on California's Channel Islands. Where do island foxes live?

In the year 2000, four of the subspecies faced extinction. But through the joint efforts of conservation organizations, government agencies, involved local citizens of all ages and dedicated biologists in the field, all of the endangered Channel Island fox populations are recovering. What does recovery look like?

Thank you to everyone: our friends, neighbors, concerned students and global partners. You all are playing an active role in helping to save the Channel Island fox.

There is still more work to do: You can play an important roll in providing lifelong identification for an island fox.

Microchipping 500 Island Foxes

What is small and makes a BIG difference for endangered Channel Island foxes?

Microchips or Passive Identification Tags (PIT)

This summer you can help make a big difference for island foxes. With help from kids, friends, baseball fans and even a dog, Friends of the Island Fox has raised $2,500 for 250 microchips for island foxes on the northern islands that are part of Channel Islands National Park.

At the annual meeting of the Integrated Island Fox Recovery Team, FIF learned that 250 microchips are also needed to provide individual identification for young island foxes on Santa Catalina Island.

The biologists on Santa Catalina Island work hard to keep island foxes safe from a variety of threats:

• cars
• domestic dogs and cats
• injury from other island foxes
• fishing equipment
• motorcycles
• raccoons that bring disease from the mainland
• even fire

the tiny microchip goes under the skin

An identification microchip allows biologists to positively identify each individual island fox. 

As the number of island foxes on Santa Catalina stabilizes at approximately 1,500 individual animals, more resources are need to monitor their success.

For just $10 you can fund a microchip that will provide an island fox with lifelong identification. Use the PayPal button in the upper right corner to Donate Now.

Good News on Channel Island Fox Recovery

Have you heard the good news? 

All four of the subspecies of endangered Channel Island foxes are doing well. In fact, three of the subspecies are considered to be close to recovered. What constitutes recovery?

1. Population numbers that have returned to healthy levels
2. Reduction of threats (those that caused the original near extinction and/or new challenges to survival)
3. Stability of the first two for at least five years

A graph of the population figures from Santa Cruz and Santa Catalina Islands shows the rapid declines toward extinction in the late 1990s. (Caused by unnatural golden eagle predation on Santa Cruz and introduced distemper virus on Santa Catalina.) 

From 2000 to 2007 island foxes increased in captive breeding facilities on each of the islands and were gradually released into the wild. Once the threats to their survival were reduced, populations of island foxes increased rapidly in the wild. Golden eagles were relocated and bald eagles were reestablished on the northern islands, while vaccinations for distemper and rabies were instituted across the islands.

On both Santa Cruz and Santa Catalina the island fox populations now fluctuate around a number that represents the carrying capacity or maximum population that can survive on each island's resources. The population of any living species alters naturally in response to available food, water and habitat.

The population numbers for island foxes are compiled annually by biologists in the field each autumn. These hard-working people  from across the six islands come together each year in June with veterinarians, scientists and government officials to discuss the status and threats to each of the six subspecies of island fox. We will have more from the annual meeting of the Integrated Island Fox Recovery Team as we compile our notes. It's been a happy busy week.

Hats Off to Foxes!

Endangered Channel Island foxes have friends across the United States. 

For the second year in a row the Fort Collins Colorado Foxes are bringing awareness about the endangered island fox to fans in Colorado. The Foxes are part of a summer Mountain Collegiate Baseball League. Last year the team helped FIF reach our goal to inoculate 400 island foxes against the distemper virus.

 This year, when: 

the Fort Collins Foxes meet the Boulder Collegians

on June 15th in Fort Collins, CO

the team will raffle off a replica Major League jersey to raise funds to help support microchipping 250 young island foxes.  (More on June 15 events and the drawing)

If you can't attend the game you can still support foxes by wearing one of the many styles of Foxes' baseball caps. When you purchase a Foxes baseball cap on-line, the team will make a 15% donation to Friends of the Island Fox. 

So raise your hats to the Fort Collins Foxes!

A Day on Santa Cruz Island

Saturday, June 1 Friends of the Island Fox led an adventurous day trip to Santa Cruz Island and the endangered Channel Island fox made 56 new friends!

Island Journal - Santa Cruz Island

Would you believe the boat is still at the end of the dock?

The fog was thick as we arrived at Prisoner's Harbor on Santa Cruz Island, but it helped keep the day moderate in temperature. 

It was fascinating to see how much the native plants in the restored wetland had grown in a year. (Santa Cruz wetland in 2012) Gone were the green and yellow flags marking the newly planted vegetation. In their place were blooming Santa Cruz Island buckwheat, leggy willows and a melange of wetland plants. 

Looking across the planted wetland toward the dead snag

 Despite the low rainfall this year, two ponds were attracting a variety of insects and birds including the rare island scrub jay (Aphelocoma insularis). 

We had hardly stepped off the pier when we had our first view of the scrub jay flying overhead. Throughout the day we saw numerous individuals; some carrying food to nests on the hillsides.

Everyone was keeping an eye open for an island fox. In the early afternoon a male island fox came to investigate the lower area near the barn and picnic tables. He appeared several times, sniffing through the vegetation, marking his territory and eventually climbing up the hillside.

It was a great day. We were able to see both of Santa Cruz Island's unique creatures in one afternoon. A huge thank you to all of the people that came out with Friends of the Island Fox. Through their participation in this event, each person helped fund a microchip for an endangered island fox this coming fall.
