A few days ago, Miguel Ordeñana, NHMer and local biologist working on the Griffith Park Connectivity Study, captured images of the elusive gray fox, Urocyon cinereoargenteus. Fortunately, I'm able to speak fox (growing up on a farm in England gives you certain skills), and have, through the magic of Photoshop, been able to translate his "Ring-ding-ding-ding-dingeringeding's" and "Fraka-kaka-kaka-kaka-kow's" into English.
*If you have no idea what the heck I'm talking about, you may want to check out Ylvis' sensational internet hit, "What Does the Fox Say?" Sure the fox they are talking about is most likely the red fox, Vulpes vulpes, but hey, I think you'll get the idea!
This is what the gray fox says:
All kidding aside, this is great news. According to Miguel, it is only the third time he's captured images of gray foxes in L.A., after almost two and half years of camera trapping! Why is this?
Mostly, it's because there just aren't many living in urban Los Angeles. They've been documented in the Baldwin Hills, on a golf course in South Los Angeles (not too far from the Museum), and in both Elysian and Griffith parks. Miguel, and other scientists studying urban carnivores, note that they "seem to be finding pockets of habitat that have enough resources, tree cover, and relatively low densities of coyotes." Even though gray foxes are very adaptable due to their small size and omnivorous diet, the larger, more social and aggressive coyote seems to have won out in the local wild dog war.
But, they're out there as Miguel's camera traps can attest, they're just pretty secretive. Not only are they mostly nocturnal, they also take to hiding while at rest. This can be in their underground den, in your backyard brush pile, or even up a tree! Gray foxes are one of the few Canids that can climb trees! By rotating their forearms, they can hug the trunk of a tree and propel themselves up the trunk with their hind legs. They've been known to scale heights of up to 60 feet, and sometimes they even build dens in the leafy reaches. How's that for vertical living in Los Angeles?
