|Tree squirrels were not a problem in Davis until the 1990's. First reports of damage in gardens came in from southeast Davis and El Macero. Within a couple of years tree squirrels were throughout South Davis, then East Davis. By the mid-2000's tree squirrels were in Central and North Davis, and now damage reports come from all parts of town.|
Squirrels may be the second most populous large animal after ducks in the arboretum. (In fact, if you count ground squirrels and arboreal squirrels in the same category (much as all ducks could be lumped together), there are probably a lot more squirrels.) Easily the most visible rodent species in Davis, the fox squirrel (Sciurus niger) makes its home in trees all around the city. While most (if not all) of the squirrels in Davis are brown, some areas (notably Marysville, KS and Washington DC) have significant populations of black squirrels (they are the same species, just a different color).
Their name is actually quite poetic. It derives from an ancient Greek word meaning "shadow tailed".
Both ground squirrels and tree squirrels can damage plants and crops. Ground squirrels are a problem on farms, while tree squirrels harm garden and landscape plants in town. Tree squirrels are a protected game species, so they can only be killed during squirrel hunting season. They are considered edible. Ground squirrels are not protected. They don't taste good.

Tree squirrels are extremely numerous on the UCD campus, spawning the Fox Squirrel Contraceptive Research Project. The project has two key objectives: to reduce the campus fox squirrel population before they cause problems, and to test a new birth-control drug that wildlife biologists hope will help them manage other mammals that are pests in some places, such as deer and ground squirrels. The goal "is to limit their ecological and human-health impacts as effectively and humanely as possible." This article has further details.

2005-03-02 12:37:19 They're so cute. Too bad they're savage, rabies-infected beasts. —SummerSong
According to an AP article on USA Today's website, "Rabid squirrels are extremely rare, with only eight reported cases since 1950."
2005-08-15 11:44:21 In the Philadelphia Suburbs, they're often referred to as "Goddamned Bird Feeder Tree Rats." —BlancheNonken
2005-11-27 20:51:52 I love all the frickin squirrels in Davis. They're spastic and vicious. :) —AubreyJohnson
2006-02-17 21:19:16 As my sister says, "rats with bushy tails" —MatthewTom
2006-02-17 21:49:21 Fact: baby squirrels are called kittens —KrisFricke
AFAIK, like most (all?) rodents, they are called pups, with the males being kits and the females being kittens. All the rodent breeders, associations and vets I've run into generally just call them pups (I think since sexing is difficult at an early age). Squirrels might be an exception, but I've always heard it was for all rodents. — JabberWokky, peromyscus and fancy mice fan.
2007-03-24 22:57:47 10 years ago there were no tree squirrels on campus. Maybe they were in other parts of Davis (I don't think so) but certainly not on campus. Where did they come from? —JimEvans
2007-05-12 21:32:38 Someone could have brought some squirrels onto campus in hopes of starting a population on campus. Some people did that with Black Squirrels at Kent State. Pretty soon Black Squirrels took over and became the unofficial mascots of the school. (There are some black ones in Palo Alto)—Jedron
2007-05-16 13:24:22 The other day I saw two bluebirds fighting a squirrel. The birds were jumping around on the ground and then swooping up and attacking the squirrel and the squirrel swatting at them. Also, I once saw a squirrel beatboxing around 5 or 6 in the morning. It was frightening. —BrianTrott
Probably a Scrub Jay rather than a bluebird. —JimEvans
2007-05-16 13:29:36 One more story involving Davis squirrels. A couple weeks ago I was biking and I biked passed a dead squirrel with a crow pecking at it. Then the crow flew away and the squirrel was runover by an SUV. This bothered me, because it was my birthday and I think that has to be some sort of bad omen. —BrianTrott
2007-05-17 08:59:50 I think its cool when the squirrels on campus at the MU run around the trees at high rates of speed. Do you think they get dizzy?... —MyaBrn
2007-05-17 19:29:15 It's nice to see a resurgence in the squirril population, cats had then pretty much under control for quite some time —StevenDaubert
I've now seen tree squirrels in the Stonegate area (far west Davis). So, the spreading of tree squirrels appears to be continuing.
Hmm, I'm not so sure about this, when I moved to davis in '99 there were no tree squirrels to be found in most of the city, since then the Eastern Fox squirrels have expanded rapidly taking over much of campus but you'll notice not to far into the rest of town yet. I doubt house cats had much to do with this. —AlexMandel
The brown tree squirrells are certainly exploding population wise in the last 2 years, they were just a trace species on campus for 40 years. I wonder if the removal of the owl boxes was part of why the population has very very rapidly exploded
2008-04-09 17:14:28 Has anyone seen the wierd squirrel with that crazy eye problem? What is up with that?!? Freaky! —emargie
2008-10-14 14:14:05 So what do we do now? Should we start an erradication program? —rgrasso
2008-10-14 19:57:00 Davis squirrels are so cute! I always wondered if the ground squirrel was a squirrel, I was calling them squirrelmunks, across between a chipmunk and a squirrel.
There is a red mouthed squirrel who lives in my walnut tree, that little jerk is always peeling walnuts over my doorstep and dropping them on the roof. He also barks at me and my cats on weekends, very rude. Is a barking vicious squirrel exhibiting symptoms of rabies, or is this normal behavior? Squirrel fights can also be quite loud, downright ferocious. —CarrieBishop
2008-10-15 01:18:44 No worries about rabies from squirrels. The raspy "barking" is normal behavior. They do it when startled or feeling threatened. According to the U.S. government CDC site: Small rodents (e.g., squirrels, hamsters, guinea pigs, gerbils, chipmunks, rats, and mice) and lagomorphs (including rabbits and hares) are almost never found to be infected with rabies and have not been known to transmit rabies to humans.
2008-10-15 07:22:07 Squirrels in California are carriers of bubonic plague on the other hand. —NickSchmalenberger
Which is very treatable with easy and full recovery with modern medicine (assuming you go to a doctor). —jw
2008-10-15 15:24:58 Yes, rodents can carry the bacteria Yersinia pestis, which is also known as bubonic plague, but it is the fleas that bite the rodents, and then bite a human that transmits it. So, you aren't going to get it by being attacked by a vicious squirrel. You would have to be bitten by fleas that had bitten an infected rodent.
According to our govt's CDC website: Q. Who is at risk for getting plague?
A. Outbreaks in people occur in areas where housing and sanitation conditions are poor. These outbreaks can occur in rural communities or in cities. They are usually associated with infected rats and rat fleas that live in the home.
2008-10-15 20:52:08 these guys have taken over the town over the past 5 years. its rediculous. —ChrisWaterstraat
2008-10-15 20:54:06 I <3 squirrels. :)
2008-10-21 19:10:00 I say we take the town back, who's with me! —rgrasso
2008-11-03 10:49:12 Hormones for those little invaders. Killing them would be much more effective.
2009-04-02 22:33:13 someone please explain .. I swear I saw a squirrel near Mrak Hall the other day with the number 14 on its rump in black. Is there some kind of survey or experiment going on or have I just been watching wayyyyy too much Lost? Some of the other ones on campus seems to have weird black burn or paint marks on their rear ends, but I haven't seen any other numbers. Maybe I was hallucinating .... —LaFrance
I got a photo of one of them. —JasonAller
2009-08-18 13:12:13 Tree rats, not to be confused with pigeons which are winged rats. Philadelphia suburbs have every possible variant of rats. —AndrewSaint
2010-06-09 20:56:10 Yes, the squirrels around Mrak Hall are part of the Fox Squirrel Contraceptive research project (why's there no page for this?). They're marked with dyes for identification. —skurniaw
2010-09-30 15:11:25 The squirrels have eaten one of the pumpkins I put by the front door! Rotten things - these were grown by my mother-in-law for my young son. Is there any way to deter the critters from destroying the other pumpkin? Painting it with toxic chemicals? —NoelBruening
Try spraying it with Hot Pepper Wax spray. You should be able to find it at Davis Ace Hardware. —DonShor
We don't actually carry it; our wholesale distributors don't stock it. But thanks for the plug! —Don
2010-09-30 18:57:41 Squirrels are just rats with bigger tails. Here in Upstate NY, at my old place the squirrels used to throw acorns at my wife and our dogs as she walked them —Users/PeterBoulay
2010-12-27 19:33:26 I think I saw a squirrel with a shaved tail on campus. I saw it near Hart Hall and Wellman, and it looked terrified. I was wondering if their was some rat-tailed breed or something, but I really think someone just caught the poor thing and shaved its tail. How sad. —Michellaneous
They lose them as a defense mechanism when evading predators. Well, the loss isn't the defense mechanism... it's the fact that it looks like there's a big fuzzy body to grab, but all the hunter gets is a bunch of fur and a squirrel gets away (minus their tail). They also shed them annually, however I believe local squirrels would only lose their tail during the spring molt (they generally don't lose their tail during the fall shedding). There are also a whole slew of parasites that cause hair loss, and — while I can't speak for squirrels in specific — many other types of rodents chew off each other's hair as a type of dominance (in the types of rodents I'm more familiar with, it's called "barbering"). It's also possible you saw a different local rodent that you mistook for a squirrel. If it looked terrified, it might be because it was flushed out into the open. Other than squirrels, most local rodents really don't like being in the open, and tend to limit their time outside of cover. ⁓ʝ⍵
