There's a Logic To How Squirrels Bury Their Nuts (berkeley.edu)
sandbagger shares an announcement from the University of California:
Like trick-or-treaters sorting their Halloween candy haul, fox squirrels apparently organize their stashes of nuts by variety, quality and possibly even preference, according to new UC Berkeley research... Fox squirrels stockpile at least 3,000 to 10,000 nuts a year and, under certain conditions, separate each cache into quasi "subfolders," one for each type of nut, researchers said... Over a two-year period, the research team tracked the caching patterns of 45 male and female fox squirrels as the reddish gray, bushy-tailed rodents buried almonds, pecans, hazelnuts and walnuts in various wooded locations on the UC Berkeley campus...
Using hand-held GPS navigators, researchers tracked the squirrels from their starting location to their caching location, then mapped the distribution of nut types and caching locations to detect patterns. They found that the squirrels who foraged at a single location frequently organized their caches by nut species, returning to, say, the almond area, if that was the type of nut they were gathering, and keeping each category of nut that they buried separate. Meanwhile, the squirrels foraging in multiple locations deliberately avoided caching in areas where they had already buried nuts, rather than organizing nuts by type.

That's a really interesting resea - SQUIRREL!

You think about him going balls deep in the trim?
You are desperate.
It's like squirrels were porn hoarders in a previous life. Nuts Organization 101.
In all seriousness though, it's remarkable what many, even seemingly simple-minded, animals are capable of.
And MSNBC squirrels go nuts.
Surely worthy of an Ig Nobel prize.

UC Berkeley Campus? Study invalid! All the squirrels were high from the second-hand pot smoke and probably whatever traces of acid were in the soil.
I had a sucky sig.
Cant cite a reference, but a local university where I live actually studied squirrels burying their nuts when they knew they were being observed vs. the opposite. It turns out squirrels, when knowing they are being watched will fake bury nuts and then move to another location and really bury the nut. Wilkes University- Wilkes Barre PA, Kirby Park squirrel study- an observation.
I was feeding a ground squirrel p-nuts when I was camping. He would take them out of the shell and pack the nuts in his cheeks until both sides were full. He ran to his burro under a tree branch and then returned for more. This went on for 30 minutes.
For nuts associated with squirrels.
Let's say a competing species is able to smell almonds, but not other nuts. If all the almonds are separated into their own cache, then the competitor would only be able to sniff out the squirrel's almond cache, leaving their other nut caches safe. However, if they mix almonds in at all of their caches, then the competitor will smell the almonds in all of their caches, and thus find (and eat) all of their cached nuts. Separating the nuts thus prevents them from putting all their eggs in one basket, and the squirrel is less likely to starve because all its nuts were stolen. Those who sort their nuts survive and reproduce, those who don't die, et voila evolution.
Corruption is convincing someone that the selfless ideal is the same as their selfish ideal.
The real question is how they track calories.
They're not squirrels, they're tree rats. I fucking hate tree rat bastards, who are always stealing bird seed, chewing through wires, and making nests in attics. They are useless animals who lack intelligence and spend most of their lives stealing from bird feeders and taunting dogs. Tree rats are evil and deserve to be eaten by dogs or shot on sight. My hate is strong and I'm damned proud of it. In fact, my hate is getting stronger as I talk to you people. However, I'm not racist, and there's nothing racist about this post. I'm sure all the nutty tree rat lovers will use ad hominem attacks to justify their adoration of the disgusting rodents. It will prove that even they can't defend the evils of tree rats. And no, I'm not racist. I hate all colors of tree rats, whether they're gray, red, brown, black, or albino. They're all evil bastards that steal from respectable animals like birds and can carry rabies. They infest our college campuses, rummaging through the trash for scraps of food to sustain their miserable existence while pretending to act friendly around our young people. I hate tree rats with every fiber of my being. Tree rats should be shot on sight.
Note to moderators: This is a parody of a copy-and-paste racist troll that frequently appears on Slashdot. It's unfortunate that I have to say this, but I intend this post to be funny. There really isn't anything racist about it, just an obsessive hatred of everything about tree rats. The author may or may not actually despise tree rats.

Surprised there were even nuts left after the pot-induced munchies kicked in....
Badum-tish!
What sorting algorithm do they use? Bubble sort?
Now that monkeys built a planet-wide communication network, nothing surprises me anymore.

...male and female fox squirrels...
Thanks. I'd been wondering how that worked.
"Like trick-or-treaters sorting their Halloween candy haul, fox squirrels apparently organize their stashes of nuts by variety, quality and possibly even preference..."
My buddy used to date a girl like that.
I've calculated my velocity with such exquisite precision that I have no idea where I am.
Google will go tree by tree with sonar or even x-ray equipment to categorize every nut and target the squirrels better.
the caching patterns of 45 male and female fox squirrels as the reddish gray, bushy-tailed rodents buried almonds, pecans, hazelnuts,walnuts and leftover pizza in various wooded locations on the UC Berkeley campus...
ftfy. This IS UC Berkeley afterall.
In the midwest-US, the gray squirrels are,,,,,, uh,,,, not that sophisticated about things.
1. When they bury a nut, they immediately urinate on the spot. IF they ever managed to find the [whatever] again, this would be the way I would have guessed that they were doing it. And-
2. Often a blue jay or other larger bird will follow a squirrel around, wait until it buries a nut and takes a couple hops away, and then the bird will dig up the nut and eat it. As the squirrel watches. And the squirrel (standing literally a foot away) doesn't seem to be able to mentally connect the significance of these two sequential events.
I've seen the local squirrels in the yard "feeding the birds" lots of times.
There's not always a bird--but even so, I don't know that I've ever seen any squirrel recover anything it buried.
You didn't build that.
"A reminder to those of our viewers who missed our story last week on the influx of so-called Killer Dope in urban areas around the country: Weekend Update has been analyzing the samples of marijuana sent to us anonymously all week.
"We are pleased to report that, so far, the only significant finding has been that if you force a baby squirrel to smoke seven hundred cannabis joints a day, he will become disoriented, and seems to take the laws of self-preservation less seriously, tending to play with his nuts rather than store them."
"Slow down, Cowboy! It has been 3 years, 7 months and 26 days since you last successfully posted a comment."
Why would this surprise anyone? We've known that animals (and not just mammals, either) can use logic for a while now.
The notion that animals do not "think" is an artifact from the bad old days when it was widely believed that animals do not feel pain.

You are welcome on my lawn.
Another source for true random numbers is gone.
Mod parent DOWN!
I studied wildlife biology at UC Berkeley, and even had to do some work with squirrels. This study is interesting, but I'm very glad to have not been responsible for tracking those squirrels and studying their caches of nuts.
Once upon a time squirrels were just another species competing for food and evading predators but now humanity has, for the most part, minimized the species that preyed upon squirrels and at the same time declared them "cute" and started giving them handouts of peanuts, corn, whatever. With such an abundance of food squirrels of urban and suburban areas have gotten quite sloppy about caching their food. Other less desirable rodents take advantage of that poorly hidden food to flourish. TL;DR: Kill off the squirrels if you ever have a rat problem in your area.
You almost had me fooled until you said "animams." That's when I figure out that you're really a squirrel.
p.s. I know we're talking about cache denial of service attacks, but you should also watch out for cache poisoning attacks if you're anywhere near my uncle's yard.
The word you were looking for was compartmentalization.
Canada's "The Nature Of Things" TV documentary series, hosted by Dr. David Suzuki, covered this very topic of squirrel food hoarding behaviour in a 2012 episode called "Nuts About Squirrels":

The show highlights the work of Prof. Mike Steele and team at Wilkes, as well as that of Prof. Joel Brown at the University of Illinois, and Dr. Sarah Parton at Hampshire College.
This new UC Berkeley research adds to a fascinating topic.
I deny that I have not avoided attaining the opposite of that which I do not want.
As long as universities have Economics departments, I don't want to hear one word about how any scientific research is "wasting" money.
Additionally, academic research projects involve making funding proposals and submitting applications for at least one grant (and often several) coming from non-governmental entities, so gripes about waste of taxpayer dollars are not based on a realistic view.

I wish all the girls were like telephone poles
I'd be a squirrel and stuff nuts in their holes
no one has mentioned that royalsocietypublishing.org interface is actually readable !
Yet another file system to use?
I'm more amazed that a squirrel would own a pack animal.
Suck it's DAMN nuts NERDS
There's a logic to how *I* bury my nuts...
Knowing this information. Who the hell cares!
You mean squirrels have discovered they shouldn't store everything in one spot?
If by that you mean they're the ones who don't massage or edit their coverage, which NBC, CBS, and CNN have all been caught doing, then okay, they're not a news network.
I'm not too sure about this study. I did not RTFA .... but how were the sources of the nuts, say trees, distributed? Common sense tell me nearest path from source to cache would be ideal. And maybe the trees were already ordered. Would the squirrel go out of its way to store nut to a far away categorized cache?
Nice Freudian slip.
Your life is in shambles because you are a do-nothing loser. Obummer enabled it to continue and get worse. That might've made you feel good but It's not healthy.
All the squirrels were wondering who's been fucking with their nuts.
When Fascism comes to America, it will call itself Anti-Fascism, and tell you to give up your guns.
LOL you are an idiot. Can't believe you fell for that troll.
Sometimes you feel like a nut, sometimes you don't
