Coyotes have a natural talent for survival, and they are built to thrive in any environment, including cities where food is readily available everywhere.

As it has been noticed multiple times, coyotes have deciphered how semaphors work and wait for the red light to cross the street.

Black bears

Studies have shown that female black bears living in urban areas aged one to one and a half years weighed nearly twice as much as their country counterparts. Some of those urban female bears produced cubs, while none of the rural bears of the same age reproduced.

Curiously, bears seem to know when it is trash day and will scavenge for food in trash cans on those dates specifically.

Raccoons

Raccoons that live in urban environments are more exploratory than their country cousins, taking more time to investigate the squares. Some raccoons even figure out how to yank bungee cords off of trash cans .

These city animals are also more social, traveling in pairs more often than their rural relatives.

Bald eagles

Believe it or not, in the 1960s, the bald eagle was on the verge of extinction due to the use of pesticides. But since those pesticides have been banned, their population has rebounded, and they're no longer on the list of endangered species.

City eagles need only a place to nest and a clean source of food, which can even be a trashcan, and they’ve figured out how to use city infrastructure like cellphone towers, bridges, and cranes along waterways .

Pigeons

Possibly the most urban animal on the list, aside from rats, pigeons are uniquely suited to urban life. They can recognize human faces , so they know which people have fed them before.

These creatures have an incredible ability to distribute themselves, so there are never more pigeons than available food. A park with twice as much food as another park will also have twice as many pigeons.

Booklice

Whether we see it or not, our homes are filled with insect life. One of them, booklice, has found that the starch in book bindings makes an ideal food source.

Booklice have adapted to suck the moisture directly out of the air and can live off that vapour for three weeks, avoiding dehydration.

Squirrels

Squirrels and urban environments have gotten along for a long time now. There’s ample food and shelter, and few natural predators. They’ve learned to live in much greater densities in cities than they do in other environments, and they can tell which humans will feed them .

Sparrows

The sparrows that live in New York City have become night owls, staying out later to feed because the bright lights around buildings draw plenty of insects .

Rats

Almost no one would call a rat clean, but contrary to popular belief, city rats tend to carry fewer diseases and parasites than rural ones because they have less contact with livestock excrement from farms, and their human neighbors don’t harbor many parasites.

Ospreys

Ospreys have seen their numbers grow in North America partially because they have forsaken trees in favor of building their 250-pound nests on power poles, cell phone towers, channel markers , and other human-made structures.

Crows

Crows are very smart creatures, and they have learned to use the city infrastructure to their advantage. These birds drop nuts and bones from great heights to crack the hard outer shells so that they can reach the food inside. City crows simply drop the previously impenetrable food into the street and let the cars crack it open .

Tomcods

Nature can adapt to almost anything, and tomcods are living proof of this. A very polluted segment of the Hudson River is home to these humble fish, who have adapted to its contaminated waters through genetic variations that allow them to thrive in such conditions.

A natural monument of unparalleled beauty, painstakingly carved over millions of years by the Colorado River , The Grand Canyon’s layered bands of red rock reveal more than just a part of the history of the land, but also offer a humbling window into deep time and Earth’s origins.

President Theodore Roosevelt himself was one of the foremost advocates for the preservation of the Grand Canyon area , frequently visiting to hunt and revel in its natural beauty. Before the arrival of Europeans, the area was continuously inhabited by various Native American groups, who often dug and carved their settlements directly into the ancient rock.

Located in the western Sierra Nevada mountains of Central California, Yosemite Valley’s granite cliffs, towering waterfalls, and ancient sequoias draw millions of visitors each year. Shaped by the action of glaciers during most of the last 30 million years , today its lush forests and incredibly diverse fauna are a living monument to our country’s biodiversity.

The towering granite peaks that encircle the valley, including Half Dome and El Capitan , are famed for their impressive rock walls and the breathtaking vistas they offer to hikers from above.

A geothermal wonderland, home to geysers, hot springs, and bubbling mud pots , Yellowstone is a wildlife haven where bison, grizzly bears, and wolves roam freely amidst its stunning natural features. Moreover, Yellowstone not only holds the distinction of being the first national park in the U.S. but also in the whole world, setting a precedent for conservation laws and standards that would be emulated worldwide.

Interestingly, the Yellowstone Caldera—the volcanic system responsible for the park’s intense geothermal activity—is the largest in North America and is considered a dormant "supervolcano." In the past, large eruptions from this region likely contributed to the extinction of many species, blanketing much of central North America in ash.

At the heart of Alaska lies Denali, North America's tallest peak. Officially named Mount McKinley until 2015, the peak was renamed after the native word for the mountain, which fittingly means "the high one."

The region surrounding the legendary mountain became a National Park in 1917 , and since that time the rugged landscape of the park has been a haven for outdoor enthusiasts, offering unique opportunities for wildlife viewing. The pristine landscape features a diverse mix of forests, deciduous taiga, tundra, and glaciers , preserving a slice of untouched wilderness that highlights the raw, untamed beauty of Alaska.

With its mist-shrouded peaks and verdant forests, the Great Smoky Mountains are one of the most scenic and alluring landscapes of the United States.

A subrange of the Appalachian Mountains, the soothing vistas of lush forests growing above the ancient peaks are often veiled by a hazy blue-ish mist , which gives the name to the region. The mysterious fog is caused by various organic compounds emitted by the lush vegetation, which end up forming dense vapor columns.

Zion's breathtaking sandstone formations are truly a sight to behold. The region is renowned for its towering cliffs, narrow slot canyons, expansive mesas, and captivating natural arches , each sculpted by the forces of time and nature into awe-inspiring works of art.

With a geological history that spans over 150 million years , Zion National Park is a testament to the immense geological forces that have shaped our land over millennia.

One of the world's most famous waterfalls, Niagara Falls is an emblem of America’s diverse natural beauty. Straddling the international border between Canada and the United States, millions of gallons of water cascade over its cliffs every minute , drawing visitors from both nations to marvel at this awe-inspiring natural spectacle.

Formed by the Niagara River, which channels the waters from Lake Erie into Lake Ontario before ending up in the Atlantic, the falls experience a rate of erosion of almost a foot per year. If the erosion continues at this pace, in about 50,000 years the falls will completely erode the remaining 20 miles to Lake Erie and cease to exist.

If you are eager to witness the true raw power of nature in action, Hawaiʻi Volcanoes National Park is the place to go. Home to two of the world's most active volcanoes, Kilauea and Mauna Loa , the park is teeming with primeval scenes and dramatic contrasts. From lava tubes to lush rainforests and stunning beaches, the islands abound with natural wonders.

Acknowledging its unique natural attributes, the park earned the prestigious designation of International Biosphere Reserve in 1980, followed by World Heritage Site status in 1987.

Dance marathons

Image: Ardian Lumi

Dancing has always been a praised activity for having some fun and passing the time. It’s simple and requires nothing but a music-playing device. So, back in the ‘20s, people felt the need to find a new twist for this basic entertainment and so they thought making dance marathons was a great idea.

How did they work? The concept was as simple as dancing: Couples would compete to see who could dance the longest all for a shot at cash prizes. But we’re not talking hours here—the contest could last for days! Audiences watched in fascination (and a bit of morbid curiosity, we might add) as exhausted dancers pushed their bodies to the limit. Remember, this was a time when missing out on a chance for quick money and a bit of fun was not a possibility!

Flagpole sitting

Image: Jonathan Simcoe

We don’t know if he was trying to break a record or if he just needed some alone time, but after Alvin "Shipwreck" Kelly climbed atop a flagpole in 1924 and stayed there for over 13 hours, a new fad was born: flagpole sitting.

And speaking of basic trends, this is exactly as you read it: People all over America were climbing up and sitting on flagpoles to see how long they could stay up there. We can all agree that these people were after entertainment and a bit of competition. And it got so serious the record eventually stretched to an astonishing 49 days!

By the 1930s, though, the thrill wore off and the fad faded, but the absurdity of it all remains—and earned it a spot on this list!

Stickball and stoopball

Image: Jeremy Stewardson

Sports today are no longer just about playing the game. For most of them, you need a lot of equipment, which is rather expensive, especially if you’re going to use it in the streets with your friends from the block.

Back in the ‘20s, baseball equipment was hard to come by. As a result, American kids in crowded urban areas came up with their own inventive versions of the game: stickball and stoopball. The fun behind this trend? Using whatever they had on hand to play: Broomsticks for bats, rubber balls, and parked cars or stoops as bases. The games required nothing more than creativity and a few friends. And no one can deny—the 1920s were indeed a creative time!

Johnny on a pony

Image: freestocks

This is a trend that started in the 1940s, and the names used for this game are simply hilarious: "Strong horses, weak donkeys," "Hunch, Cuddy, Hunch," just to name a few.

Johnny on a Pony, or Buck Buck, was a rough-and-tumble game in which one team bent over to form a "horse" while the other team took turns jumping on their backs, trying to knock them over .

You may think this was innocent, but not quite—it was chaotic, sometimes painful, and, more often than not, left participants in a pile of tangled limbs.

Kids do not care for those things, but the game’s physical nature made it exhilarating and dangerous at the same time. That’s why, eventually, concerned parents and schools stepped in and banned it—one too many injuries to keep it going!

Drive-In movie theaters

Image: Tim Mossholder

Movie theaters are great, but drive-in movie theaters are even better—they were the ultimate fusion of America’s love for cars and entertainment.

The first official drive-in theater opened in 1933, and it was an alternative for families to a fun and affordable night out under the night sky, watching a movie from the comfort of their car . No wonder this quickly became a beloved American pastime. And you can already imagine whose favorite this was: Teens and young couples, who enjoyed the privacy of their cars while watching the latest films of the time.

The trend slowly faded as film rentals became more popular, and later with the rise of streaming platforms. However, keep an eye out for this one, because it’s definitely making a comeback!

Miniature golf

Some may argue that the fad behind miniature golf never actually died, and that’s partially true. But let’s go back to the time it first appeared and all the craze that erupted around it.

It wasn’t until Garnet Carter opened his "Tom Thumb" golf course in 1927 that miniature golf became a true sensation . Located in Lookout Mountain, Tennessee, Carter’s course wasn’t just about putting greens; it also featured miniature goblins, gnomes, and other fun obstacles for players.

We don’t know if he knew this would be so successful, but Carter went all in: He patented the design, and it hit the jackpot—miniature golf became a nationwide success.

Hood ornaments

Funny thing about the past: You didn’t always need to be extravagant to be trendy—sometimes, just a tiny ornament on your car was enough.

In the 1920s and ‘30s, no car was complete without a stylish hood ornament adorning its radiator . At first, these ornaments were designed to check on the engine temperature. But they soon evolved into artistic expressions of each brand to showcase wealth and personality.

We all recognize the winged goddess or the jaguar jumping out of the car, right?

However, this trend didn’t last long. As car designs modernized and safety became a concern, hood ornaments became less common, and eventually, all but disappeared. If you see a car with one of these today, you can bet it’s worth more than one can get in a lifetime!

Kilroy was here

Image: Richard Cohrs

There are two generations: One is looking for Waldo, and the other is looking for Kilroy. Which one do you belong to? Now, if you’re wondering who Kilroy is, let us tell you.

Kilroy was a doodle, and the complete drawing consisted of Kilroy and a message that read "Kilroy Was Here." This graffiti popped up just about everywhere during World War II.

The doodle, featuring a bald, long-nosed figure peeking over a wall, was a symbol of American presence and humor. It’s said that Kilroy was originally the work of James J. Kilroy, a shipyard inspector who scrawled it on equipment he inspected.

But that was just the beginning—the drawing spread to every corner of the globe. Have you ever come across one?

Swing dancing

Image: Clarisse Meyer

Few things are as time-sensitive and culturally reflective of an era, don’t you think? In the early 20th century, specifically during the 1920s and 1930s, the dance that dominated every dance floor was swing . And it makes perfect sense—this was the Jazz Age, so swing dancing perfectly matched the exuberance of that music!

Dances like the Lindy Hop, Charleston, and Jitterbug took over dance halls, with young people spinning, jumping, and flipping to the infectious rhythm of big bands.

Older generations sometimes frowned upon the flashy, intimate dance styles, but that only made them more appealing to rebellious youth. Some things never change!

Stamp collecting

Image: Tolga deniz Aran

Philately is the collection of stamps or the study of them, and it became a fad across the United States during the 1920s and the ‘30s. Why? Here is the reason.

Stamps offered people a way to explore history, geography, and art. They were everyday items, easy to access, and nobody could escape them. For example, President Franklin D. Roosevelt was an avid stamp collector. Not that he needed them to learn about history or art—it was just a way to have fun.

Contrary to other trends we have discussed, schools encouraged this hobby, because it was both educational and enjoyable. Collecting stuff is a never-ending trend; there are all kinds of collections today and stamp collections today are almost invaluable!
