Even if you live in a big city, you probably see wildlife on a regular basis. Namely, you're sure to run into a lot of squirrels, even in the densest urban areas. And if you happen to live on a college campus, well, you're probably overrun with them. While some people might view them as adorable, others see them as persistent pests bent on chewing on and nesting in everything in sight. But in honor of National Squirrel Appreciation Day, here are 15 reasons you should appreciate the savvy, amazing, bushy-tailed critters.

1. They can jump really, really far.

In one study [PDF] of the tree-dwelling plantain squirrels that roam the campus of the National University of Singapore, squirrels were observed jumping almost 10 feet at a stretch. In another study with the eastern ground squirrel, one researcher observed a squirrel jumping more than 8 feet between a tree stump and a feeding platform, propelling itself 10 times the length of its body. Flying squirrels, obviously, can traverse much farther distances midair—the northern flying squirrel, for instance, can glide up to 295 feet [PDF].

2. They're very organized ...

In fact, they may be more organized than you are. A 2017 study found that eastern fox squirrels living on UC Berkeley's campus cache their nuts according to type. When given a mixture of walnuts, pecans, almonds, and hazelnuts, the squirrels took the time to hide each type of nut in a specific place. This method of "spatial chunking" may help them remember where the nuts are when they go to retrieve them later. Though the study wasn't able to determine this for sure, the study's results suggested that the squirrels may have been organizing their caches by even more subtle categories, like the size of the nuts.

3. ... But their forgetfulness helps trees grow.

Tree squirrels are one of the most important animals around when it comes to planting forests. Though they may be careful about where they bury their acorns and other nuts, they still forget about quite a few of their caches (or at least neglect to retrieve them). When they do, those acorns often sprout, resulting in more trees—and eventually, yet more acorns for the squirrels.

4. They help truffles thrive.

The squirrel digestive system also plays an important role in the survival of truffles. While above-ground mushrooms can spread their spores through the air, truffles grow below ground. Instead of relying on the air, they depend on hungry animals like squirrels to spread their spores to host plants elsewhere. The northern flying squirrel, found in forests across North America, depends largely on the buried fungi to make up its diet, and plays a major role in truffle propagation. The squirrels poop out the spores unharmed on the forest floor, allowing the fungi to take hold and form a symbiotic relationship with the tree roots it's dropped near.

5. They're one of the few mammals that can sprint down a tree head-first.

You may not be too impressed when you see a squirrel running down a tree, but they're actually accomplishing a major feat. Most animals can't climb vertically down head-first, but squirrel's back ankles can rotate 180°, turning their paws all the way around to grip the tree trunk as they descend.

6. Several towns compete for the title of "Home of the White Squirrel."

Squirrels are a more popular town mascot than you might think. Surprisingly, more than one town wants to be known as the "home of the white squirrel," including Kenton, Tennessee; Marionville, Missouri; the Canadian city of Exeter, Ontario; and Brevard, North Carolina, the location of the annual White Squirrel Festival. But Olney, Illinois may be the most intense about its high population of albino squirrels. There is a $750 fine for killing the all-white animals, and they have the legal right-of-way on roads. There's an official city count of the squirrels each year, and in 1997, realizing that local cats posed a threat to the beloved rodent residents, the city council banned residents from letting their cats run loose outdoors. In 2002, the city held a 100-Year White Squirrel Celebration, erecting a monument and holding a "squirrel blessing" by a priest. Police officers wore special squirrel-themed patches for the event.

7. They could aid in stroke research.

Ground squirrels hibernate in the winter, and the way their brains function while they do may help scientists develop a new drug that can limit the brain damage caused by strokes. When ground squirrels hibernate, their core body temperature drops dramatically—in the case of the arctic ground squirrel, to as low as 26.7°F, possibly the lowest body temperature of any mammal on Earth. During this extra-cold hibernation, a squirrel's brain undergoes cellular changes that help its brain deal with reduced blood flow. Researchers are currently trying to develop a drug that could mimic that process in the human brain, preventing brain cells from dying when blood flow to the brain is cut off during a stroke.

8. Their fur may have spread leprosy in the Middle Ages.

If you always warn your friends not to pet or feed squirrels because they can spread disease, put this story in your back pocket for later: They may have helped leprosy spread from Scandinavia to the UK in the 9th century. Research published in 2017 found a strain of leprosy similar to a modern variant found in squirrels in southern England in the skull of a woman who lived in England sometime between 885 and 1015 CE. The scientists suggest that the leprosy may have arrived along with Viking squirrel pelts. "It is possible that this strain of leprosy was proliferated in the South East of England by contact with highly prized squirrel pelt and meat, which was traded by the Vikings at the time this woman was alive," one of the authors told The Guardian. That may not be the most uplifting reason to appreciate squirrels, but it's hard not to admire their influence!

9. They're more powerful than hackers.

While energy companies may worry about hackers disrupting the power grid, squirrels are actually far more powerful than cyber-whizzes when it comes to sabotaging our electricity supply. A website called Cyber Squirrel 1 documents every public record of squirrels and other animals disrupting power services dating back to 1987. It has counted more than 1100 squirrel-related outages across the world for that time period, which is no doubt a vast underestimate. In a 2016 survey of public power utilities, wildlife was the most common cause of power outages, and for most power companies, that tends to mean squirrels.

10. They can heat up their tails to ward off predators.

California ground squirrels have an interesting way of scaring off rattlesnakes. Like cats, their tails puff up when they go on the defense. A squirrel will wave its tail at a rattlesnake to convince the snake that it's a formidable opponent. Surprisingly, they whip their tails at their foes whether it's light or dark outside. Squirrels can control the blood flow to their tails to cool down or keep warm, and they use this to their advantage in a fight, pumping blood into their tails. Even if the rattlesnakes can't see the bushy tails, researchers found in 2007, they can sense the heat coming off them.

11. They help scientists determine whether a forest is healthy.

Researchers look at tree squirrel populations to measure just how well a forest ecosystem is faring. Because they depend on their forest habitats for seeds, nesting sites, and food storage, the presence and demographics of tree squirrels in an area is a good bellwether for the health of a mature forest. Studying changes in squirrel populations can help experts determine the environmental impact of logging, fires, and other events that alter forest habitats [PDF].

12. They can lie.

Gray squirrels know how to deceive. They can engage in what's called "tactical deception," a behavior previously only seen in primates, as a study in 2008 found. When they think they're being watched by someone looking to pilfer their cache of food, the researchers discovered, they will pretend to dig a hole as if burying their acorn or nut, but tuck their snack into their mouth and go bury it elsewhere.

13. They used to be America's most popular pet.

Though some states currently ban (or require permits for) keeping squirrels as pets, it was once commonplace. Warren G. Harding kept a squirrel named Pete who would sometimes show up to White House meetings and briefings, where members of Harding's cabinet would bring him nuts. But keeping a squirrel around wasn't just for world leaders—the rodent was the most popular pet in the country, according to Atlas Obscura. From the 1700s onwards, squirrels were a major fixture in the American pet landscape and were sold in pet shops. Despite Harding's love of Pete, by the time he lived in the White House in the 1920s, squirrel ownership was already on the wane, in part due to the rise of exotic animal laws.

14. The mere sight of just one squirrel could once attract a crowd.

The American cities of the 1800s weren't great places to catch a glimpse of wildlife, squirrels included. In fact, the animals were so rare that in the summer of 1856, when a gray squirrel escaped from its cage inside a downtown New York apartment building (where it was surely living as someone's pet), it merited a write-up in The New York Times. According to the paper, several hundred people gathered to gawk at the tree where the squirrel took refuge and try to coax the rodent down. In the end, a police officer had to force the crowd to disperse. The paper did not document what happened to the poor squirrel.

15. In the 19th century, they were tasked with teaching compassion.

In the mid-1800s, seeking to return a little bit of nature to concrete jungles, cities began re-introducing squirrels to their urban parks. Squirrels provided a rare opportunity for city slickers to see wildlife, but they were also seen as a sort of moral compass for young boys. Observing and feeding urban squirrels was seen as a way to steer boys away from their "tendency toward cruelty," according to University of Pennsylvania historian Etienne Benson [PDF]. Boy Scouts founder Ernest Thompson Seton argued in a 1914 article that cities should introduce "missionary squirrels" to cities so that boys could befriend them. He and other advocates of urban squirrels "saw [them] as opportunities for boys to establish trusting, sympathetic, and paternalistic relationships with animal others," Benson writes.

But young boys weren't the only ones that were thought to benefit from a little squirrel-feeding time. When the animals were first reintroduced to parks in the 19th century, feeding squirrels was considered an act of charity—one accessible even to those people who didn't have the means of showing charity in other realms. "Because of the presence of urban squirrels, even the least powerful members of human society could demonstrate the virtue of charity and display their own moral worth," Benson writes. "Gray squirrels helped reshape the American urban park into a site for the performance of charity and compassion for the weak." Even if you were too poor to provide any sort of charity for someone else, you could at least give back to the squirrels.

Bonus: They used to hate tax season, too.

Though notably absent from big cities, much of the U.S. was once overrun by squirrels. The large population of gray squirrels in early Ohio caused such widespread crop destruction that people were encouraged—nay, required—to hunt them. In 1807, the Ohio General Assembly demanded that citizens not just pay their regular taxes, but add a few squirrel carcasses on top. According to the Ohio History Connection, taxpayers had to submit a minimum of 10 squirrel scalps to the town clerk each year. Tennessee had similar laws, though that state would let people pay in dead crows if they couldn't rustle up enough squirrels.

Hee-Haw: The Wild Ride of "Dominick the Donkey"—the Holiday Earworm You Love to Hate

Everyone loves Rudolph the Red-Nosed Reindeer. He’s got the whole underdog thing going for him, and when the fog is thick on Christmas Eve, he’s definitely the creature you want guiding Santa’s sleigh. But what happens when Saint Nick reaches Italy, and he’s faced with steep hills that no reindeer—magical or otherwise—can climb?

That’s when Santa apparently calls upon Dominick the Donkey, the holiday hero immortalized in the 1960 song of the same name. Recorded by Lou Monte, “Dominick The Donkey” is a novelty song even by Christmas music standards. The opening line finds Monte—or someone else, or heck, maybe a real donkey—singing “hee-haw, hee-haw” as sleigh bells jingle in the background. A mere 12 seconds into the tune, it’s clear you’re in for a wild ride.

 

Over the next two minutes and 30 seconds, Monte shares some fun facts about Dominick: He’s a nice donkey who never kicks but loves to dance. When ol’ Dom starts shaking his tail, the old folks—cummares and cumpares, or godmothers and godfathers—join the fun and "dance a tarentell," an abbreviation of la tarantella, a traditional Italian folk dance. Most importantly, Dominick negotiates Italy’s hills on Christmas Eve, helping Santa distribute presents to boys and girls across the country.

And not just any presents: Dominick delivers shoes and dresses “made in Brook-a-lyn,” which Monte somehow rhymes with “Josephine.” Oh yeah, and while the donkey’s doing all this, he’s wearing the mayor’s derby hat, because you’ve got to look sharp. It’s a silly story made even sillier by that incessant “hee-haw, hee-haw,” which cuts in every 30 seconds like a squeaky door hinge.

There may have actually been some historical basis for “Dominick.”

“Travelling by donkey was universal in southern Italy, as it was in Greece,” Dominic DiFrisco, president emeritus of the joint Civic Committee of Italian Americans, said in a 2012 interview with the Chicago Sun-Times. “[Monte’s] playing easy with history, but it’s a cute song, and Monte was at that time one of the hottest singers in America.”

Rumored to have been financed by the Gambino crime family, “Dominick the Donkey” somehow failed to make the Billboard Hot 100 in 1960. But it’s become a cult classic in the nearly 70 years since, especially in Italian American households. In 2014, the song reached #69 on Billboard’s Holiday 100 and #23 on the Holiday Digital Song Sales chart. In 2018, “Dominick” hit #1 on the Comedy Digital Track Sales tally. As of December 2019, the Christmas curio had surpassed 21 million Spotify streams.

“Dominick the Donkey” made international headlines in 2011, when popular BBC DJ Chris Moyles launched a campaign to push the song onto the UK singles chart. “If we leave Britain one thing, it would be that each Christmas kids would listen to 'Dominick the Donkey,’” Moyles said. While his noble efforts didn’t yield a coveted Christmas #1, “Dominick” peaked at a very respectable #3.

 

As with a lot of Christmas songs, there’s a certain kitschy, ironic appeal to “Dominick the Donkey.” Many listeners enjoy the song because, on some level, they’re amazed it exists. But there’s a deeper meaning that becomes apparent the more you know about Lou Monte.

Born Luigi Scaglione in New York City, Monte began his career as a singer and comedian shortly before he served in World War II. Based in New Jersey, Monte subsequently became known as “The Godfather of Italian Humor” and “The King of Italian-American Music.” His specialty was Italian-themed novelty songs like “Pepino the Italian Mouse,” his first and only Top 10 hit. “Pepino” reached #5 on the Billboard Hot 100 in 1963, the year before The Beatles broke America.

“Pepino” was penned by Ray Allen and Wandra Merrell, the duo that teamed up with Sam Saltzberg to write “Dominick the Donkey.” That same trio of songwriters was also responsible for “What Did Washington Say (When He Crossed the Delaware),” the B-side of “Pepino.” In that song, George Washington declares, “Fa un’fridd,” or ‘It’s cold!” while making his famous 1776 boat ride.

With his mix of English and Italian dialect, Monte made inside jokes for Italian Americans while sharing their culture with the rest of the country. His riffs on American history (“What Did Washington Say,” “Paul Revere’s Horse (Ba-cha-ca-loop),” “Please, Mr. Columbus”) gave the nation’s foundational stories a dash of Italian flavor. This was important at a time when Italians were still considered outsiders.

According to the 1993 book Italian Americans and Their Public and Private Life, Monte’s songs appealed to “a broad spectrum ranging from working class to professional middle-class Italian Americans.” Monte sold millions of records, played nightclubs across America, and appeared on TV programs like The Perry Como Show and The Ernie Kovacs Show. He died in Pompano Beach, Florida, in 1989. He was 72.

Monte lives on thanks to Dominick—a character too iconic to die. In 2016, author Shirley Alarie released A New Home for Dominick and A New Family for Dominick, a two-part children’s book series about the beloved jackass. In 2018, Jersey native Joe Baccan dropped “Dominooch,” a sequel to “Dominick.” The song tells the tale of how Dominick’s son takes over for his aging padre. Fittingly, “Dominooch” was written by composer Nancy Triggiani, who worked with Monte’s son, Ray, at her recording studio.

Speaking with NorthJersey.com in 2016, Ray Monte had a simple explanation for why Dominick’s hee-haw has echoed through the generations. “It was a funny novelty song,” he said, noting that his father “had a niche for novelty.”

Cats Make Facial Expressions, But Not Everyone Can Read Them

Science has finally confirmed what humans have suspected for centuries: Cats are inscrutable creatures prone to peculiar behavior. Some of us, however, are still capable of picking up on their subtle emotional cues, including facial expressions, without relying on clues like tails, ears, or whiskers.

This new evidence of a cat’s slightly malleable face comes from a study in the journal Animal Welfare. Researchers at the University of Guelph in Ontario, Canada, recruited 6329 participants to watch a series of 20 video clips featuring cats reacting to either a positive or negative event. A positive interaction was defined as a feline approaching a human for a treat or an owner-identified action the cat traditionally found pleasant, like climbing into a favorite spot. A negative response was when a cat was confronted with something it wanted to avoid, was prevented from going into an area or outside, or was displaying an obvious sign of distress, like growling. (Sounds were edited out.) Most clips were from YouTube, though some were submitted by veterinarians and university colleagues. Breeds with long hair that might obscure facial changes were omitted. Most respondents were cat owners, and 74 percent were women 18 to 44 years old.

Using these brief clips, the researchers asked subjects to classify the cats as exhibiting positive or negative behavior by relying only on closely cropped footage of a cat’s face. They couldn’t rely on the tail or any other body language. The result? The average score was just 59 percent correct, accurately identifying a cat’s mood in an average of 12 out of the 20 clips. These humans, in other words, had little idea what a cat was experiencing based solely on their faces.

So why do researchers think they have any expression at all? Roughly 13 percent of subjects scored well on the test, getting at least 15 of the 20 questions correct. Those that did well were generally people who had extensive experience with cats, like veterinarians. That led researchers to conclude that people can become more attuned to the subtle flickers of emotion that may pass over a cat’s face.

“They could be naturally brilliant, and that’s why they become veterinarians,” Georgia Mason, a behavioral biologist and the study’s senior author, told The Washington Post. “But they also have a lot of opportunity to learn, and they’ve got a motivation to learn, because they’re constantly deciding: Is this cat better? Do we need to change the treatment? Does this cat need to go home? Is this cat about to take a chunk out of my throat?”

The paper appears to offer encouraging evidence that “cat whisperers” really do exist. If you’re curious whether you could be one of them, you can take a shortened version of the video test online.
