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 ↓

I observed two Eastern Fox Squirrels in the trees along Adams Blvd. in front of Mount Saint Mary's College. They were within 50 feet of each other, but they did not interact. They scratched at the grass to eat something and climbed back up into the trees.

I saw two Eastern Fox Squirrels in the South Lawn area of the Mount Saint Mary's College campus within 100 feet of each other, but they were not interacting.

One squirrel was eating something out of a trash can. When I approached, it retreated to the shade under a car. It returned to the trash can as I left.

The second squirrel was scratching at the grass and eating something out of the grass. I observed this behavior for about 5 minutes before the squirrel climbed up into a tree and laid down on a branch.

I heard this Eastern Fox Squirrel chirping from across the road, as I was walking my dogs in the morning. It was perched in a California Pepper Tree. It scrambled down to the ground and back up into the branches several times as my dogs and I approached. It looked as if the squirrel was eating something in the grass. When we arrived at the sidewalk below, the squirrel perched on a branch and shook its tail at us until we left.

This afternoon, I saw an Eastern Fox Squirrel traveling east on the power lines in my back yard. The power lines continue three more houses before ending near some pine trees.

I saw this Eastern Fox Squirrel sitting on the power lines in my backyard. It was facing East and sat still for about 10 minutes before I stopped keeping track of it. Another 15 minutes later, it was gone.

Description

This Eastern Fox Squirrel was out in the middle of the road as I was driving. Trashcans had been set out for tomorrow's collection, and the squirrel had something in its mouth.

The squirrel ran across the street and jumped up into one of the pine trees, where it watched to see what I would do. Then it scampered up the branches out of sight.

I saw this Eastern Fox Squirrel in the Australian Garden of the Huntington Library.

First it was running on the ground. It stopped a couple times to watch my movements. Then it jumped up into a Callistemon viminalis and disappeared up into its branches.

Description

This Eastern Fox Squirrel was climbing a Monkey Pod tree inside the Rose Hills Conservatory at the Huntington Library and Botanical Gardens. It was not captive though. I think it climbed in through an open window.

There were many people inside the conservatory. The squirrel climbed all the way down to the ground and then back up. It stopped in the crook of two branches and turned over on its back (almost in a submissive/playful way like a dog). Then, it climbed up higher into the branches where I could no longer see it.

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 ↓
