Welcome to the Southern California Squirrel Survey!

I’m Jim Dines, a mammalogist at the Natural History Museum of Los Angeles County. My colleague, Miguel Ordeñana, and I established this project to improve what is known about the distribution of squirrels in southern California. Your contributed observations will help!

Did you know that the eastern fox squirrels commonly observed in southern California are not native to the area? As their common name implies, these tree squirrels were introduced from the eastern United States about 100 years ago. We’re interested in tracking the expansion of this introduced species, but we also hope to gain valuable insight into what is happening when the introduced eastern fox squirrel comes into contact with the native western gray squirrel. Both are large bushy-tailed tree squirrels but you can tell them apart by their color: eastern gray squirrels have reddish-brown fur and are commonly seen in urban and suburban neighborhoods; western gray squirrels have silver-gray fur and live in ...more ↓

Will ya look at the balls on that squirrel! (Sorry, just couldn't resist.)

And yes, not long after, I bought a squirrel guard. Cute, but I couldn't afford to keep feeding them!

Native to eastern US, but introduced in Calif., and probably displacing the native species here.

About

Squirrels are well-known but sometimes overlooked species of the southern California landscape. For instance, not many people realize that eastern fox squirrels are nonnative or how much their range has expanded. Similarly, the decline of the native western gray squirrel has gone unnoticed. We also want to learn more about the distribution and behavior of other understudied species such as ...more ↓
