Study sheds light on squirrel psychology
The ability of grey squirrels to learn from observing others is highlighted in a new study The research shows how squirrels can quickly learn from watching their peers, particularly if it relates to stealing food. The research adds to growing evidence that animals are primed to learn quickly about what is most important to their survival and that they learn by observing others. It is the first study to test the ability of gray squirrels to learn from observation. (2009-07-28)

Grey squirrels beat reds in 'battle of wits'
Problem-solving powers may help to explain why grey squirrels have taken over from native red squirrels in the UK, new research says. (2018-02-20)

Leaving home is beneficial for male squirrels but not for females, study shows
In the world of squirrels, moving away from your home turf has better outcomes for males than for females, according to a new study by University of Alberta ecologists. (2019-12-13)

Squirrels use snake scent
California ground squirrels and rock squirrels chew up rattlesnake skin and smear it on their fur to mask their scent from predators, according to a new study by researchers at UC-Davis. (2007-12-19)

Squirrels use 'chunking' to organize their favorite nuts
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. (2017-09-13)

Early squirrel gets the real estate, U of G study finds
Those young squirrels now scampering around your neighborhood were born in this year's earliest litters and are more likely to survive than squirrels born later and still curled up in their nests, according to a new University of Guelph study. That's because squirrels with early birth dates are first out of the nest and therefore more likely to find vacant spots to store their food for the winter. (2017-07-12)

Stress is good thing for parents, babies in squirrel world
Stressed-out mothers raise stronger, heartier offspring -- at least among squirrels. In a new study, international researchers -- including University of Guelph biologists -- say squirrels tailor their parenting to meet the varied conditions facing their young. (2013-04-19)

Human leprosy found in British red squirrels
Scientists have discovered human leprosy in British red squirrels, uncovering one leprosy-driving bacterial strain, in particular, that is similar to that responsible for outbreaks of the disease in medieval Europe. (2016-11-10)

Squirrels winning at outwitting trees' survival strategy
In Science, Andrew McAdam at Michigan State outlines how red squirrels have figured out a way around the elaborate ruse trees have used to protect their crops of tasty seeds. The remarkable part: The squirrels are divining the arrival of bumper crops of spruce cones months before the cones ever materialize and then betting on those crops with the most expensive evolutionary collateral -- a second litter of pups. (2006-12-21)

Study shows grey squirrels are quick learners
They may be viewed by some as an invasive species or a commonplace pest of public parks, but a new study from the University of Exeter has shown that grey squirrels are actually quick learners capable of adapting tactics to improve efficiency and reap the best rewards. (2015-07-06)

When it comes to female red squirrels, it seems any male will do
Researchers have found that female red squirrels showed high levels of multimale mating and would even mate with males that had similar genetic relatedness, basically mating with their relatives. Researchers from the University of Alberta in Canada, and the University of Sheffield in England, studied a population of red squirrels over a period of three years near Kluane National Park in southwest Yukon. (2008-06-20)

Giant flying squirrel fossil from a Barcelona landfill clarifies the squirrel family tree
A study just published in eLife shows a fossil found in a Barcelona landfill to be about 11.6 million years old -- making the Miopetaurista neogrivensis specimen the oldest-known giant flying squirrel discovered. (2018-10-24)

New York squirrels are nuts about city life
Curtin University-led research has shown squirrels have adapted to New York City's human behaviour, allowing them to thrive just as well, if not better, than their fellow squirrels in the woods. Dr Bill Bateman, Senior Lecturer at Curtin's Department of Environment & Agriculture, led the study that proved eastern grey squirrels were able to modify their behaviour in urban environments and prevent unnecessary responses when humans acted in a predictable manner, such as staying on the footpath. (2014-07-22)

Arctic ground squirrels muscle up to hunker down
When Arctic ground squirrels are getting ready to hibernate they don't just get fat -- they pack on muscle at a rate that would make a bodybuilder jealous. And they do it without suffering the harmful effects that high levels of testosterone and other anabolic steroids usually cause. University of Toronto Scarborough (UTSC) researchers have started to untangle how the squirrels manage it, and their results could someday have implications for human health. (2011-09-15)

New hope for the red squirrel
A number of red squirrels are immune to squirrelpox viral disease, which many believed would lead to the extinction of the species, scientists have discovered. Scientists led by the Zoological Society of London have identified eight cases in which free-living red squirrels have survived infection with the squirrelpox virus by mounting an immune response. The research is published today in the Springer journal Ecohealth. (2008-10-16)

Parasite carried by grey squirrels negatively impacts red squirrel behavior
Research published in the Journal of Animal Ecology reveals a new mechanism of how grey squirrels affect native red squirrels in Europe through parasite-mediated competition. (2020-04-16)

Don't blame grey squirrels: Their British invasion had much more to do with us
DNA profiling reveals grey squirrels are not as good invaders as we think, and that humans played a much larger role in spreading them through the UK. (2016-01-26)

Red squirrels stricken by medieval strain of leprosy, study shows
Leprosy in Britain's red squirrels is being caused by the same species of bacteria responsible for human infections, a DNA study has found. One of the strains -- affecting squirrels on Brownsea Island, off England's south coast -- shares close similarities with that responsible for outbreaks of the disease in medieval Europe. (2016-11-10)

Baby boomer squirrels master tricky timing
Female squirrels who align their reproduction to take advantage of food-rich years and align have more pups that survive to maturity, according to new research from UAlberta biologists (2017-08-24)

Researchers discover link between stress and unhealthy microbiomes
Red squirrels living in a low-stress environment harbor healthier communities of micro-organisms, a result that might hold implications for human health, according to a new University of Guelph-led study. (2016-01-06)

In the squirrel world, prime real estate is determined by previous owner, study reveals
Researchers found that if a squirrel inherits territory from a male rather than a female, it will have about 1,300 more cones in its midden. This stored energy will keep the squirrel alive an extra 17 days. For females it means she will enough food to breed earlier, resulting in her offspring leaving the nest earlier. This shows how the behavior of a complete stranger can impact the genetic contribution of another. (2019-02-13)

Squirrels listen in to birds' conversations as signal of safety
Grey squirrels eavesdrop on the chatter between nearby songbirds as a sign of safety, according to a paper by Marie Lilly and colleagues at Oberlin College in the United States, publishing Sept. 4, 2019 in the open-access journal PLOS ONE. (2019-09-04)

Immune system turned off during hibernation in squirrels
Ground squirrels' immune system essentially quits when the animals hibernate each winter, researchers report. When scientists injected hibernating squirrels with a pseudo-bacteria that would normally provoke an immune response, they were surprised what they found: the squirrels didn't react at all. But when the squirrels aroused briefly from hibernation days later - as they do normally about once a week during winter - the squirrels spiked a fever as if they had just been infected. (2002-04-01)

Study reveals fox squirrels' 'tell-tail' signs of frustration
Fox squirrels flick their tails when they can't get a cherished nut in much the same way that humans kick a vending machine that fails to deliver the anticipated soda or candy bar, according to new research from the University of California, Berkeley. (2016-05-11)

Snowshoe hare carcasses feed more then the usual suspects, study shows
What do lynx, flying squirrels, ravens, and wolverines have in common? They will all scavenge from snowshoe hare carcasses under the right conditions, according to a new study by University of Alberta ecologists. And they're not alone. In fact, researchers documented 24 different species feeding from snowshoe hare carcasses in Canada's northern boreal forest. (2020-08-13)

Highway deaths highest for males - Male urban squirrels, that is
A year-long study on the Texas A&M University campus showed that males are more likely than females to die on the road, and scientists believe it's because the males dart about through the streets more. But wait. It was urban squirrels, not students, who were radio-tagged and followed by Dr. Roel Lopez, wildlife assistant professor, both to find out about the 350-or-so fox squirrels on the campus and to teach undergraduate students how to trap, handle and monitor animals. (2003-04-29)

Northern Ireland's recovering pine marten population benefits red squirrels
The recovery of pine marten in Ireland and Britain is reversing native red squirrel replacement by invasive grey squirrels, according to new research presented at the British Ecological Society's annual meeting in Belfast today. (2019-12-12)

Study reveals new ways deadly squirrelpox is transmitted to red squirrels
Native red squirrels have declined throughout Britain and Ireland for the last century due to a combination of habitat loss and the introduction of the North American eastern grey squirrel. More recently its few remaining populations have been devastated by an insidious pox virus passed to them by the alien invaders. (2014-02-24)

Finnish forest management guidelines fail to protect the flying squirrel
A new study determined the habitat requirements for flying squirrels and compared them to those included in the recently amended Forest Act. The main finding was that the Finnish Nature Conservation Act does not adequately protect the old growth forests where flying squirrels live. (2018-06-26)

Squirrels place winning bet in unpredictable world
In an evolutionary game of tug-of-war, red squirrels have gained the upper hand over the cunning spruce trees, says new University of Alberta research that suggests the clever animals are staying one step ahead of its food source. (2006-12-21)

Red squirrels: Altruists or self-serving survivalists?
U of A researcher Jamieson Gorrell discovered a female red squirrel adopted a newborn foundling. The foundling was related to its adoptive mother as was the case four other times in the 20-year study. This confirms Hamilton's Rule applies to nonsocial animals. Altruistic behavior in red squirrels is restricted to family members. (2010-06-02)

Squirrels need good neighbours

The keys to the squirrel's evolutionary success in the face of climate change have been identified
Squirrels form a diverse family of rodents. Nearly 300 species have been described, and they occur in every land environment on the planet, from tropical forests to hot and cold deserts. But why are there so many species? A study led by researchers from the Complutense University of Madrid and the Institute of Geosciences (UCM-CSIC) has examined the characteristics of squirrel species that contribute to their evolutionary success in the face of global climate change. (2020-11-25)

New study gives squirrels plenty of food for thought
A new study by the University of Exeter has shown that persistence and the ability to choose the right behavior to solve a problem are important aspects of problem solving in the common squirrel when they were learning to unravel challenges in the quest for nourishment. (2016-01-18)

Red squirrels making comeback as return of pine marten spells bad news for invasive grey squirrel
The number of red squirrels is on the increase in Ireland thanks to the return of the pine marten, a native carnivore, a new survey led by NUI Galway has found. (2020-06-17)
