Few
things symbolize the onset of fall quite so well as the sight of a squirrel
scampering around a park, industriously burying nuts. As the weather cools and
the leaves turn, squirrels engage in this frantic behavior to prepare for the
upcoming shortages of wintertime.
But have
you ever wondered how effective the squirrel's outdoor pantry project could
really be? After going to all that effort to conceal its winter stash, how does
the squirrel actually find the buried treasure again, when it's needed most?
First,
let's backtrack slightly, because the way that squirrels bury
their food yields some interesting clues. Animals that store food to survive
the winter don't just do so randomly: They typically use one of two strategies.
Either they larder-hoard — meaning they store all their food in one place — or
they scatter-hoard — meaning they split up their bounty and stash it in many
different locations. [The 12
Biggest 'Little' Mysteries of Fall — Solved!]
First study to show squirrels
using sophisticated memorizing strategy to sort their bounty

Summary:
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
research.
We can all be guilty of over-eating during the winter - and it seems Britain’s squirrel population is no exception.
The small furry creatures might need to join their human friends in going on a diet this January after piling on the pounds thanks to an exceptionally mild winter.
Wildlife experts said that the unusually balmy temperatures meant more food was available than usual, allowing the squirrels to fatten up.
Squirrels do not hibernate, but in the cooler months they put on up to a quarter of their body weight in fat reserves to keep them warm. They also grow a thicker winter coat which can make them appear bigger.
“With the extra layers of fat and thicker winter coat this can make them look much bigger.”
Iolo Williams, Wildlife Expert
However, the survival technique has gone further than normal this year, with fatter than ever squirrels being spotted in parks.
TV presenter and nature expert Iolo Williams said there was a plentiful supply of nuts and seeds available still for squirrels to gorge on.
He told Wales Online: “Because of the mild wet weather there has been an abundance of food for squirrels. There has been no shortage of nuts, seeds and fungi for them to eat and store.

Three people in Germany who worked as squirrel breeders and who all died from brain inflammation may have contracted a new strain of virus from their squirrels, according to a new report of the cases.
The new virus strain belongs to a group of viruses called bornaviruses, which typically infect animals such as horses, sheep and birds. Researchers have debated whether this group of viruses can cause disease in people.

If jam-packed highways, back-to-back meetings and too little time for "to-do" lists make you tense, consider the red squirrels of the Yukon . Regardless of how much food they have, these mammals experience a significant amount of stress when their numbers increase.
During population booms, this compact mammal, which weighs about as much as a cell phone, breeds earlier in the year and produces smaller-sized litters with pups that grow quickly. But what cues the females to hasten their offspring's growth? To answer this question,Ben Dantzer at the University of Michigan and colleagues with the Kluane Red Squirrel Project hooked up hundreds of speakers in the forest and simulated a burgeoning population by blaring squirrel chatter.
One by one, the bushy-tailed residents of Moscow's parks have been disappearing. The problem: Russians have gone nuts for squirrels.
City official Alexei Gorelov says he has received multiple reports of squirrel poaching in local parks. In response, municipal authorities beefed-up security for all of Moscow's green areas.
Gorelov, who heads the ecological control department of eastern and north-eastern Moscow, said that more police patrols would be dispatched to fend off poachers, who can be fined up to 20,000 rubles (£357).
Squirrels, which are of little use for their meat or their fur, are primarily poached to become pets. Russian websites offer the creatures for sale at 5,000 rubles each.
Bodie, Calif., is, technically, a gold-rush ghost town and a state historical park. But a more accurate way to describe it would be “squirrel heaven.” According to Pacific Standard, a thriving population of Belding’s ground squirrels has pretty much taken over the town:
They pop out from under the floors of shuttered bars and tear around meadows littered with rusting mine machinery. They stand attentively in the road, as if ready to collect entrance fees.
And, actually, the only reason the squirrels are thriving here is that there’s a town that humans more or less abandoned. The forests where these squirrels used to live are warming up, and they’ve had to more to higher altitudes. But for some mysterious reason, places where humans used to live still make good squirrel hangouts. Standard:
When residents of a leafy street noticed that their soap and shower gel was going missing from their bathrooms they thought they were going mad.
But that was until one of the thieves was caught disappearing out of a window with a bar of soap - and the mystery gang was unmasked as squirrels.
Now residents of the Kentish Town road have complained to Camden Council for planting trees too close to their homes and demanding they be cut down.
The pests are notorious for devouring anything they can get their hands on. TV wildlife expert Chris Packham said: “Squirrels will chew anything even if it's obviously inedible”.
Johnny Murphy, 75, who has lived in the street for 40 years, told the Camden New Journal: “Nobody knows where the stuff goes or what on earth they want to do with it, but we know it’s them because they’ve been caught red-handed in the past.
“No one can leave their windows open because you open one window and they spot it. They leap straight in from the branches.”
The Animal Clinic of Regina got a surprise this week when a city worker brought in six squirrels fused together by their tails.
Although quite uncommon, the veterinarian community does have a term for it — squirrel kings — since the rodents move together as one giant squirrel when their tails are entangled.
“It just doesn’t happen too often,” said Dr. Steven Kruzeniski, who works with the Animal Clinic of Regina.
“It’s a pretty rare thing to see but I have seen it happen once before.”
This particular group of six were nesting near a pine tree and sap fused their tails together. A city of Regina worker found the young squirrels and brought them to the clinic.
The animals were sedated and the veterinarian team worked to untangle the mess of tails. Their tails were then shaved of the matted fur and they were given antibiotics to prevent infection.
Dr. Kruzeniski says the young squirrels were lucky to keep their tails as in some more extreme cases they have to be amputated.
“They were brought in quickly,” said Dr. Kruzeniski, “They all got to keep their own tails, which is not always the case.”
The six squirrels have been released back into the city’s green-space.
Lower quantities of seeds and
nuts in the wild will bring more birds and squirrels into gardens
October 2012. The last few weeks have seen Grey Squirrels pile into gardens.
With reports of patchy seed and nut crops in the countryside this autumn, these
dextrous and divisive garden guests are turning to bird feeders.
Keep an eye on your bird food
- squirrels are coming! Householders who record garden wildlife through the
year-round British Trust for Ornithology (BTO) Garden BirdWatch survey have
revealed a big influx of Grey Squirrels over recent weeks. Garden use is
currently up by a third compared with the same period in 2009-2011.
Friend or foe?
Seed and nut availability appears to be patchy in the countryside this autumn,
leaving wildlife in search of alternative food. For Grey Squirrels, as well as
for birds, garden bird feeders provide a nutritious fix. While some
householders welcome squirrels into their gardens, others consider them to be
pests that chomp through expensive bird food and feeders.
BTO research shows that many
bird species, such as Jay, Coal Tit and Nuthatch, turn to gardens in greater
numbers when seeds, such as beechmast, are scarce during autumn and winter. It
is, therefore, possible that there will be increased competition at garden
feeders over the coming months, not only between birds but also between birds
and Grey Squirrels.
Olympic beach volleyball players have come across an unexpected handicap - squirrels burying their nuts on their courts.
The rodents have been burying beechnuts and acorns on six sandy practice courts at London's St James's Park.
And bikini-clad players have been left grimacing as they land barefoot on the squirrel snacks.
Groundsmen now have to rake the sand before practice sessions, reports The Sun.
Six courts, two warm-up courts and a hospitality lounge have been created in the leafy lakeside park close to Buckingham Palace.
The 15,000-seat main competition arena in nearby Horseguards Parade has not been affected.
A London 2012 source told the newspaper: "It's nuts but true. It seems squirrels have been invading the courts and either hiding or dropping their nuts.
"But it won't affect the competition because the sand is regularly raked."
Visitors to Wildwood are in luck this week with the first sightings of our baby red squirrels.
These new babies, born on 23rd April and now venturing out of their nest boxes for the first time are Wildwood's first brood this year. After maturing at the park they will be released as part of Wildwood's red squirrel conservation project aimed at preventing their nationwide extinction by re-introducing red squirrels back to the UK.
Once grown up the squirrels will be transported to the island of Anglesey in Wales to live wild and free, helping form a buffer population to safeguard the species against national extinction.
Red squirrels went extinct in Kent in the 1960's and many of us can remember them from our childhood and many areas like Kent once teemed with these beautiful acrobats of the trees.
Peter Smith, Wildwood Trust's Chief Executive said:
"Red squirrels are one of the most beautiful animals in the UK but sadly they face extinction unless urgent action is taken. But it's not yet too late. If we can help restore areas of woodland to a native state and make a concerted effort, we might just be able to tip the balance back in the red squirrel's favour."
"Wildwood Trust, as a charity, is committed to restoring our native and once native species and will continue to champion the restoration of natural woodlands."
Red Squirrels are just some of the huge range of British animals that can be seen at the Wildwood Discovery Park near Canterbury. For more information visit our website at www.wildwoodtrust.org or telephone 0871 782 0081.
Wildwood's 'Wildlife Conservation Park' is an ideal day out for all the family where you can come 'nose to nose' with British Wildlife. Wildwood offers its members and visitors a truly inspirational way to learn about the natural history of Britain by actually seeing the wildlife that once lived here, like the wolf, beaver, red squirrel, wild boar and many more.
Wildwood is situated close to Canterbury, just off the A291 between Herne Bay and Canterbury.
RED SQUIRREL FACTS
The Red Squirrel - Sciurus vulgaris
Recognition:
Fur colour variable from bright ginger through to red and dark brown or black tinged with grey in winter; larger ear tufts in mid-winter which disappear by the summer; bushy tail which bleaches white by late summer in some individuals.
Head/body length 180-240mm, tail about 175mm.
Weight: juveniles 100-150g; adults up to 350g.
General Ecology:
This is the only squirrel which is native to Britain. It is active during the daytime, though in summer it may rest for an hour or two around mid-day. Squirrel nests, or dreys, are constructed of twigs in a tree fork, or hollow or above a whorl of branches close to the stem of a conifer. They are lined with soft hair, moss and dried grass. Several squirrels may share the same drey, or use the same drey on different days.
Red squirrels spend about three-quarters of their active time above ground in trees and shrubs. Their main foods are tree seeds, such as hazel nuts and seeds from conifer cones. They also eat tree flowers and shoots, mushrooms and fungi from under tree bark. Red squirrels often suffer periods of food shortage especially during July. Red squirrels are at home in conifer forests and broadleaved woodland. The distribution of red squirrels has declined drastically in the last 60 years and they are now extinct in southern England except for a few on the Isle of Wight and two small islands in Poole Harbour. Elsewhere they are confined to rather isolated populations in Wales and to only four places in central England: Thetford Chase (East Anglia), Cannock Chase (Staffordshire), Hope Forest (Derbyshire) and around Formby in Merseyside. Red squirrels are still widespread in the North of England and Scotland, but even here their range is contracting.
Breeding can begin in mid-winter and continue through the summer, depending on the weather and how much food is available. Mating chases occur where several males follow a female who is ready to mate. During chases squirrels make spectacular leaps through the tree canopy and spiral up and down tree trunks. Females have one or two litters a year, usually of about 2-3 young. Juveniles are weaned at around 10 weeks, but do not breed until they are one year old. Red squirrels in favourable habitat can live at a population density of one squirrel per hectare of woodland. Often densities are lower than this. They survive for up to six years in the wild.
Conservation:
Red squirrels are protected by law, and may not be intentionally trapped, killed or kept, or have their dreys disturbed except under licence from English Nature (EN), the Countryside Council for Wales (CCW) or Scottish Natural Heritage (SNH).
Red squirrels are considered vulnerable in Britain. However, very occasionally high densities in some Scottish forests can lead to economic damage to trees. In such cases, government agencies will assess whether to issue a licence to remove some of the red squirrels.
Historically, red squirrel populations in Britain have fluctuated widely, the species disappearing from many areas at times and recolonising at a later date. However, in the 1920s red squirrels began to be replaced by grey squirrels introduced to about 30 sites from eastern North America, between 1876 and 1929. Red squirrels seem unable to survive in the presence of greys, but the reasons for this are not fully understood. There is no evidence that grey squirrels aggressively chase out red squirrels, or that grey squirrels brought a disease with them from America which affects red squirrels. The key as to why grey have replaced red squirrels seems to be their ability to compete for food in different types of habitat. Red squirrels live in all types of woodland habitats from pure broadleaf, to mixed broadleaf and conifer, to pure conifer. However it is believed they prefer pure conifer forests because they can forage in them more efficiently and survive in them better than in broadleaf forest.
It is believed that the only real way to ensure the continued presence of red squirrels in an area is, if possible, to keep grey squirrels out, or, at least to keep their number low. This may be achieved by habitat management to alter the tree species composition and age structure of woodland to suit red but not grey squirrels. Special food hoppers which provide food for red squirrels but not the heavier grey squirrels, can help to tip the balance in favour of red squirrels. Re-introductions to large pine forests may be an important conservation tactic, although further research into the health and welfare of red squirrels during captivity and all phases of a reintroduction programme is needed.
WHERE HAVE ALL THE RED SQUIRRELS GONE?
In the past red squirrels were common. Over the last few decades we have seen a dramatic decline in numbers of red squirrels.
The red squirrel is our only native squirrel species. This century it has undergone a drastic decline and is now mainly confined to northern England, Scotland and parts of Wales.
The main cause of this decline is competition with the introduced American grey squirrel. The grey squirrel is larger than the red and better able to survive harsh weather and period of food shortage. It breeds more successfully and quickly out-competes the red squirrel for food.
Historically, red squirrels frequented the whole of the British Isles which they recolonised after the ice age. Numbers and range have always naturally fluctuated, rising and falling in relation to food availability and climate. The major decline occurred in England during the 1940s and 1050s while the grey squirrel expanded rapidly at the same time. reasons for the red squirrel decline are competition with grey squirrels, disease, habitat loss and fragmentation.
Numbers
It has been estimated that about 160,000 red squirrels remain in Great Britain. 120,000 of these in Scotland and 30,000 in England with 10,000 in Wales. There are an estimated 2.5 million grey squirrels in Britain. Populations of red and grey squirrels in Northern Ireland are currently changing. Distribution is known, however population estimates have not yet been considered.
Habitat
Without competition red squirrels can thrive in broadleaved and coniferous woodland. However, where the two squirrels exist, the red squirrel in general survives in conifer woods only as it is more specialised to feed off smaller seeds. There are a number of locations in Scotland where red and grey squirrels have been known to exist for many years, this is probably due to the habitat types. To aid the red squirrel in the long term it is important that appropriate habitat management is practiced to allow red squirrels to survive in areas that would otherwise be taken over by greys. This is easier said than done and much research is still needed before we can fully assist the red squirrel within our conifer woodlands.
OTHER RED SQUIRREL FACTS
Red squirrels can also be black, brown, cream or have white tails.
They don't hibernate.
They can leap up to 6m from tree to tree.
Their ankles are double-jointed, which allows them to swivel their feet through 180 degrees, they have sticky pads on their feet and they wee on them to get a better grip - all to help them climb.
The wee also means they mark their territories with their scent wherever they go.
They also wipe their faces along branches to leave their scent.
Squirrels weigh nuts in their hands to see if they will make good eating - too light means the nut has shrivelled inside and is thrown away.
Whenever they bury a nut in the woodland floor after holding it in their mouths, they can find it again because it will be smeared with their own individual scent from a gland in their cheek.
They take fresh fungi into the treetops to hang up to dry and store for later.
Squirrels wrap themselves in their tails, both to keep warm in winter and to shade them from the summer sun.
Sometimes they can go bald in the spring because their winter coat moults before the new summer one has grown.
They store nuts in the ground in Autumn.
Can swim.
Eat seeds, buds, leaves, flowers, shoots and fruit of many trees and shrubs, fungi, insects and occasional birds eggs.
Live in a drey made of twigs, leaves and moss built in a tree.
Moult whole coat twice a year.
Moult ear tufts and tail once in late summer.
They can live to 6 years of age.
Scientific name is Sciurus vulgaris.
Have 4 fingers and 5 toes.
They can hang upside down.
Young are called kittens.
Could have 2 litters each year with 3-4 kittens in each litter.
Kittens are born blind, pink, hairless and toothless.
The plight of the disappearing red squirrel is being highlighted in events dedicated to the native British species. But its tormenter, the American grey squirrel, is itself being slowly overwhelmed in parts of the country by the little-known black squirrel.
When Alison Thomas first saw a black squirrel dart in front of her car, she nearly swerved off the road in surprise. That was in July 2003, and as a biologist, she found this strange creature a beguiling research topic - not least to disprove the family joke that she'd imagined it.
"I decided to start my own investigations and discovered, to my great relief and to the chagrin of my family, that squirrels can indeed sometimes be black and that there is a rapidly expanding population of black squirrels in Cambridgeshire," says Dr Thomas, of Anglia Ruskin University in Cambridge.
The black squirrel is of the same species as the grey bushy-tailed creatures familiar from park and woodland walks. Its dark coat is the result of a naturally occurring mutation of the gene that governs fur pigmentation.
Other than colour, black squirrels have the same size, behaviour and habitat as greys.
"It's the same specific mutation found in the black squirrels of North America. The chances of that same mutation occurring by chance in the UK, and separately in the United States, is tiny.
"This shows that at some point, black squirrels were brought into this country from North America."
The first recorded sighting of a black squirrel was in 1912 on the outskirts of Letchworth. It's thought that, like grey squirrels, a handful of black-furred specimens were imported for a private zoo and then escaped or were released.
"People speculate that it was the Duke of Bedford who imported black squirrels, but I've been unable to confirm that - even with the help of the family's archivists," says Dr Thomas.
It took another 30 years before black squirrels were spotted on the south-west borders of Cambridgeshire.
Today they are found in a ribbon across Hertfordshire, Bedfordshire and Cambridgeshire. In some hot-spots, blacks now outnumber greys, making up an estimated three-quarters of the squirrel population in villages such as Girton in Cambridgeshire.
"They're not found anywhere else in the UK. But people have reported seeing black versions of red squirrels - a different species, remember - on the Isle of Skye," says Dr Thomas.
Amateur photographer Simon George, of Henlow in Bedfordshire, has been documenting the comings and goings of a black squirrel in his back garden for several years.
"We more or less adopted her, and called her Coffee. She would come if you called her and ate out of our hands; she loved Waitrose finest walnuts. She had a litter of six last summer and survived the snow of last winter, but we have not seen her, or any other squirrel, since March."
In his area, too, black squirrels have largely replaced greys - he speculates that this is because they're bigger.
But Dr Thomas says any differences in size or behaviour are probably down to age.
"Blacks and greys are the same species. Any differences people notice are likely to be age-related."
The rise of the black is the biggest change in squirrel demographics since the native reds almost disappeared 50 years ago from large parts of England.
This is not because black squirrels compete with greys in the way that greys compete with reds (the larger greys eat more, and carry a pox that is deadly to reds), but because the gene for black fur is dominant, just like the gene for brown eyes is dominant over blue in humans.
"Two grey squirrels cannot produce black-furred offspring, just as blue-eyed parents cannot have a brown-eyed baby," says Dr Thomas. "You need to have a black-furred parent to produce black offspring."
As wildlife watchers gear up for the Wildlife Trusts' population count for Red Squirrel Week, or for the start of the BBC's Autumnwatch on Thursday, Dr Thomas has a fond hope.
"I'd like there to be a count of how many black squirrels there are now. We're so programmed to expect grey squirrels that it's a shock when you first see a black one - it's startling and interesting."
This red squirrel could be reaching for his nuts, but we think he's showing off (Photo: Caters).
He was snapped by wildlife photographer Marek Paluch, who captured the fuzzy squirrel near Opole, Poland, demonstrating just what a mover and a shaker he is.
Prince Charles spent yesterday spotting Wildwood Trust’s Red Squirrels, which have been released to the island of Anglesey.
The Prince, who is Patron of the Red Squirrel Survival Trust, went on a special trip to observe the squirrels which were born and raised at the Wildwood, Woodland Discovery Park, near Canterbury.
Visitors to Wildwood can see this year’s babies, which are also destined to be released to the island later in the year. Visitors are advised to come promptly at 10.00am as squirrels like a long nap during lunchtime, especially during sunny weather.
The new squirrel babies, once grown up, will be transported to join their cousins on Anglesey to live wild and free, helping form a buffer population and safeguard the species against national extinction. The project is managed my ‘The Friends of the Anglesey Red Squirrels’ which was set up in 1999 by Anglesey residents who wished to assist in the conservation of the islands small red squirrel population.
Red squirrels went extinct in Kent in the 1960's and many of us can remember them from our childhood. How easy it is for people to forget that Kent once teemed with these beautiful acrobats of the trees.
Peter Smith, Wildwood Trust's Chief Executive said:
“It is great that the Prince has taken time to come and see the results of our hard work. Wildwood’s volunteers and animal keepers spend a lot of time making sure our breeding groups has everything they need to produce as many baby squirrels as we can for this important project”
"Red squirrels are going to continue to decline towards extinction unless urgent action is taken. But it's not yet too late. If we can help restore areas of woodland to a native state and make a concerted effort, we might just be able to tip the balance back in the red squirrel's favour."
Wildwood Trust, as a charity, is committed to restoring our native and once native species and will continue to champion the restoration of natural woodlands."

Populations:
Red Squirrels estimated 161,000 (10,000 Wales, 30,000 England & 121,000 Scotland)
Grey Squirrels estimated 2,250,000 ( of which 2,000,000 are in England)
FIREFIGHTERS were called to 'rescue' a squirrel - by a homeowner who was driven nuts trying to get rid of it. The Brighton crew chased the critter around the flat for 30 minutes before it jumped out of a window. 'He was leaping about all over us. It was a hilarious,' said one firefighter.
THIS bandaged baby squirrel is looking far from bright-eyed and bushy-tailed.
Named Crunchy by his carers, the four-week-old grey squirrel has been put on painkillers after tumbling from a branch when a tree surgeon sawed through his home.
Luckily he escaped serious injury save for a nasty cut on his head and is now recovering at the Wildlife Aid Centre in Leatherhead, Surrey, where he is being fed milk, nuts and biscuits.
The four-inch long squirrel was found lying injured in a garden in nearby Guildford. “He’s now feeding well, which is great news and he is very lively,” said the sanctuary’s founder, Simon Cowell.
“I think Crunchy fell from the tree and cut his head when he hit the deck or caught some branches on the way down. We have a licence that allows us to release a certain number back into the wild each year. All being well we will release Crunchy in eight weeks.
“It is okay to handle him while he is this small but as he gets older we will have to keep some distance because they have a nasty bite.”
Everyone with a bird feeder knows that a squirrel will do almost anything to get the seeds inside. When one amateur photographer captured a photo of a squirrel making a meal of an actual bird, however, he illustrated a largely unknown problem that plagues avian species.
A vast amount of evidence shows that clear and reflective sheet glass and plastic are the largest manmade threat to birds after habitat loss. A billion birds—at least—die annually from colliding with such material in the U.S. alone, and the toll worldwide is far greater.
