No, Blue Marblers, “Island Fox” is not the name of a new reality TV series. It’s one of many names for a tiny, adorably fuzzy fox that lives on six of the eight California Channel Islands. The Island Fox, also called the Island Gray Fox because of its descent from mainland gray foxes, weighs only 5 lbs as an adult and is just now recovering from near extinction.

The Island Fox has lived on the Channel Islands for thousands of years, with each island evolving its own subspecies. All the Island Foxes were thriving until the 1990s, when changes in the local ecosystem had a disasterous chain effect on the species. DDT poisoned fish, which in turn poisoned the Islands’ native bald eagles. The bald eagles’ population decline opened up turf for non-native golden eagles who were attracted by the Islands’ feral pigs. Once on the Islands, the golden eagles found Island Foxes easy prey since the foxes never had a predator, much less one that struck from above. In addition, sheep and other livestock had eaten much of the protective scrub and grasses foxes might have used for cover. Golden eagles quickly decimated the foxes. On one island, the fox population plummeted from 450 animals to 15 in just a few years.

To bring back the species, the National Park Service instituted a number of measures. Firstly, they removed golden eagles and re-introduced native bald eagles. Secondly, the Service created an ambitious captive breeding program, which you can learn more about here. And thirdly, the department is working on totally eradicating feral pigs so that golden eagles do not come back. Through this multimillion-dollar, multi-pronged approach, the National Park Service has been successful in bringing the Island Fox back from the brink of extinction in record time.

Now that Island Fox populations are recovering, the diurnal animals can be seen on the Islands living naturally. The foxes eat mostly fruit, insects, and deer mice and are devoted parents. They mate for life, having two to three pups per litter. Foxes communicate not only with body language, but with growls and short, high-pitched barks. Although they are now the subjects of active conservation, the foxes remain federally endangered. To learn more about the Foxes, and learn more about their history, you can visit the National Park Service’s page here or visit a conservancy organization here.

IT'S NOT THAT WE'RE SCREWED WITHOUT TRUMP:

"It's that we're screwed with or without him if we can't show the public that what we do matters for the long term," writes Mother Jones CEO Monika Bauerlein as she kicks off our drive to raise $350,000 in donations from readers by July 17.

This is a big one for us. It's our first time asking for an outpouring of support since screams of FAKE NEWS and so much of what Trump stood for made everything we do so visceral. Like most newsrooms, we face incredibly hard budget realities, and it's unnerving needing to raise big money when traffic is down.

So, as we ask you to consider supporting our team's journalism, we thought we'd slow down and check in about where Mother Jones is and where we're going after the chaotic last several years. This comparatively slow moment is also an urgent one for Mother Jones: You can read more in "Slow News Is Good News," and if you're able to, please support our team's hard-hitting journalism and help us reach our big $350,000 goal with a donation today.
