Bald eagles are powerful symbols of America—but there’s a whole lot more to these quirky birds.

1. YOUNG BALD EAGLES AREN'T BALD.

So obviously adult bald eagles aren't really bald, either—their heads have bright white plumage that contrasts with their dark body feathers, giving them a "bald" look. But young bald eagles have mostly brown heads. In fact, for the first four or five years of their lives, they move through a complicated series of different plumage patterns; in their second year, for instance, they have white bellies.

2. BALD EAGLES SOUND SO SILLY THAT HOLLYWOOD DUBS OVER THEIR VOICES.

It's a scene you’ve probably seen countless times in movies and on TV: An eagle flies overhead and emits a rough, piercing scream. It's a classic symbol of wilderness and adventure. The only problem? Bald eagles don't make that sound.

Instead, they emit a sort of high-pitched giggle or a weak scream. These noises are so unimpressive that Hollywood sound editors often dub over bald eagle calls with far more impressive sounds: the piercing, earthy screams of a smaller bird, the red-tailed hawk. If you were a fan of The Colbert Report, you might remember the show's iconic CGI eagle from the opener—it, too, is making that red-tailed hawk cry. Listen for yourself and decide who sounds more impressive.

3. THEY EAT TRASH AND STOLEN FOOD.

Picture a majestic bald eagle swooping low over a lake and catching a fish in its powerful claws. Yes, bald eagles eat a lot of fish—but they don't always catch them themselves. They've perfected the art of stealing fish from other birds such as ospreys, chasing them down until they drop their prey.

Bald eagles will also snack on gulls, ducks, rabbits, crabs, amphibians, and more. They'll scavenge in dumpsters, feed on waste from fish processing plants, and even gorge on carrion (dead, decaying animals).

4. BALD EAGLES USUALLY MATE FOR LIFE ...

Trash and carrion aside, they're pretty romantic animals. Bald eagles tend to pair up for life, and they share parenting duties: The male and the female take turns incubating the eggs, and they both feed their young.

5. … AND THEY LIVE PRETTY LONG LIVES.

Those romantic partnerships are even more impressive because bald eagles can survive for decades. In 2015, a wild eagle in Henrietta, New York, died at the record age of 38. Considering that these birds pair up at 4 or 5 years of age, that's a lot of Valentine's Days.

6. THEY HOLD THE RECORD FOR THE LARGEST BIRD'S NEST.

Bald eagles build enormous nests high in the treetops. The male and female work on the nest together, and this quality time helps them cement their lifelong bond. Their cozy nurseries consist of a framework of sticks lined with softer stuff such as grass and feathers. If the nest serves them well during the breeding season, they'll keep using it year after year. And, like all homeowners, they can't resist the thought of renovating and adding to their abode. Every year, they'll spruce it up with a whopping foot or two of new material.

On average, bald eagle nests are 2-4 feet deep and 4-5 feet wide. But one pair of eagles near St. Petersburg, Florida, earned the Guinness World Record for largest bird’s nest: 20 feet deep and 9.5 feet wide. The nest weighed over two tons.

7. FEMALES ARE LARGER THAN MALES.

In many animal species, males are (on average) larger than females. Male gorillas, for example, dwarf their female counterparts. But for most birds of prey, it's the opposite. Male bald eagles weigh about 25 percent less than females.

Scientists aren't sure why there's such a size difference. One reason might be the way they divide up their nesting duties. Females take the lead in arranging the nesting material, so being bigger might help them take charge. Also, they spend longer incubating the eggs than males, so their size could intimidate would-be egg thieves.

If you're trying to tell male and female eagles apart, this size difference may help you—especially since both sexes have the same plumage patterns.

8. TO IDENTIFY THEM, LOOK AT THE WINGS.

People often get excited about a big soaring bird and yell "It's an eagle!” just before it swoops closer and … oops, it's a vulture. Here's a handy identification tip. Bald eagles usually soar with their wings almost flat. On the other hand, the turkey vulture—another dark, soaring bird—holds its wings up in a shallow V shape called a dihedral. A lot of large hawks also soar with slightly raised wings.

9. THEY'RE COMEBACK KIDS.

Before European settlers arrived, bald eagles were abundant across the U.S. But with settlement came habitat destruction, and the settlers viewed the eagles as competition for game and as a threat to livestock. So many eagles were killed that in 1940 Congress passed an act to protect the birds.

Unfortunately, another threat rose up at about that time. Starting after World War II, farmers and public health officials used an insecticide called DDT. The chemical worked well to eradicate mosquitos and agricultural pests—but as it traveled up the food chain, it began to heavily affect birds of prey. DDT made eagle eggshells too thin and caused the eggs to break. A 1963 survey found just 471 bald eagle pairs in the lower 48 states.

DDT was banned in the early 1970s, and conservationists began to breed bald eagles in captivity and reintroduce them in places across America. Luckily, this species made a spectacular recovery. Now the lower 48 states boast over 9700 nesting pairs.

10. THEY'RE UNIQUELY NORTH AMERICAN.

You've probably heard of America's other eagle: the golden eagle. This bird lives throughout much of the northern hemisphere. But the bald eagle is only found in North America. It lives across much of Canada and the U.S., as well as northern parts of Mexico.

Though it may be North American, the bald eagle has seven close relatives that are found throughout the world. They all belong to the genus Haliaeetus, which comes—pretty unimaginatively—from the Latin words for "sea" and "eagle." One relative, the African fish eagle, is a powerful symbol in its own right. It represents several countries; for example, it's the national symbol of Zambia, and graces the South Sudanese, Malawian, and Namibian coats of arms.

11. THEY'RE AERIAL DAREDEVILS.

It seems too weird to be true: While flying, bald eagles sometimes grab each other's feet and spin while plummeting to the earth. Scientists aren't sure why they do this—perhaps it's a courtship ritual or a territorial battle. Usually, the pair will separate before hitting the ground (as seen in this remarkable set of photographs). But sometimes they hold tight and don't let go. These two male bald eagles locked talons and hit the ground with their feet still connected. One subsequently escaped and the other was treated for talon wounds.

12. THEIR EYES ARE AMAZING.

What if you could close your eyes and still see? Besides the usual pair of eyelids, bald eagles have a see-through eyelid called a nictitating membrane. They can close this membrane to protect their eyes while their main eyelids remain open. The membrane also helps moisten and clean their eyes.

Eagles also have sharper vision than people, and their field of vision is wider. Plus, they can see ultraviolet light. Both of those things mean the expression "eagle eye" is spot-on.

13. THEY MIGRATE … SORT OF.

If you're a bald eagle that nests in northern Canada, you'll probably head south for the winter to avoid the punishing cold. Many eagles fly south for the winter and return north for the summer—as do plenty of other bird species (and retired Canadians). But not all bald eagles migrate. Some of them, including individuals in New England and Canada's Maritime provinces, stick around all year. Whether or not a bird migrates depends on how old it is and how much food is available.

14. THEY CAN SWIM … SORT OF.

There are several videos online—like the one above—that show a bald eagle swimming in the sea, rowing itself to shore with its huge wings. Eagles have hollow bones and fluffy down, so they can float pretty well. But why swim instead of soar? Sometimes, an eagle will swoop down and grab an especially weighty fish, then paddle it to shore to eat.

Note that the announcer in the video above says that the eagle's talons are "locked" on a fish that's too heavy to carry. In fact, those lockable talons are an urban legend.

Photographer's Up-Close Images of Animal Eyes Will Have You Seeing Wildlife in a Whole New Way

Few people ever get close enough to a hippo, hyena, or crocodile to snap a photo of one, let alone get a detailed shot of their eyes. Yet that is exactly what theoretical physicist-turned-photographer Suren Manvelyan, of Armenia, has done. His macro photography series of animal eyes, spotted by My Modern Met, offers a rare look at the animal world, amplified.

Some of Manvelyan's eye photos—like that of the camel, which has three eyelids—look like strange landscapes on some distant, alien planet. The smallest details have been captured in his photos, from the kaleidoscopic irises of the chinchilla and chimpanzee to the shimmery edges of a raven's eye. If the photos weren't labeled, it might be difficult to tell what you were looking at.

"It is very beautiful and astounding," Manvelyan told Radio Free Europe/Radio Liberty. "The surface resembles the surface of other planets, with craters, rivers, and valleys. It looks like something from another world. Every time I photograph the eye, I feel myself traveling through the cosmos."

Manvelyan keeps his photography techniques secret, but he says he sometimes spends an hour with an animal just waiting to capture the right moment. To date, he has photographed both domestic animals (like a husky dog and Siamese cat) as well as exotic ones (including a variety of tropical birds and lizards). Check out some of his shots below, and visit his website to see more photos from this series.

11 Lesser-Known Animal Phobias

iStock.com/Scacciamosche

He’s dealt with elaborate booby traps, KGB agents, and a face-melting artifact, but to Indiana Jones, nothing’s more unsettling than snakes. Many people can relate. Ophidiophobia—or “the persistent and irrational fear of snakes”—affects roughly 1 to 5 percent of the global population. So does the clinical fear of spiders, also known as arachnophobia. But did you know that some people feel just as uncomfortable around chickens? From puppy-induced panic to equine terror, here are 11 lesser-known animal phobias.

1. Lepidopterophobia

Academy Award-winner Nicole Kidman is unfazed by spiders or snakes, but she can’t escape her lepidopterophobia, or fear of butterflies. As a young girl, the Australian actress once scaled a fence just so she could avoid a butterfly perched nearby. “I jump out of planes, I could be covered in cockroaches, I do all sorts of things,” Kidman once said, “but I just don’t like the feel of butterflies’ bodies.” (The Independent reported that she tried to break her phobia by spending time in a museum butterfly cage. “It didn’t work,” the actress said.) Kidman and her fellow lepidopterophobes may refuse to leave windows open in the summertime, lest a stray monarch come fluttering into their home.

2. Batrachophobia

No, frogs can’t give you warts. That urban legend—and others like it—may explain some cases of batrachophobia, a deep-seated fear of amphibians, including frogs, toads, and salamanders. It’s thought that the condition might also be linked to an overarching disdain for slimy things. By the way, if you specifically don’t like toads, then you could have a case of what’s known as bufonophobia.

3. Entomophobia

Entomophobia is a family of fears related to insects that includes lepidopterophobia, the previously mentioned butterfly-related dread. Another phobia within this group is isopterophobia, the fear of wood-eating insects like termites. Then we have myrmecophobia (the fear of ants) and apiphobia (the fear of bees or bee stings). Of course we can’t leave out katsaridaphobia, or the debilitating fear of cockroaches. “Cockroaches tap into this sort of evolutionary aversion we have to greasy, smelly, slimy things,” Jeff Lockwood, an author and professor of natural sciences at the University of Wyoming, told the BBC. “Plus, they’re defiant little bastards.”

Surrealist painter Salvador Dalí was terrified of grasshoppers. “I am 37 years old,” he wrote in 1941, “and the fright which grasshoppers cause me has not diminished since adolescence ... If possible, I would say it has become greater.” He went on to say that if a grasshopper ever landed on him while he was standing “on the edge of a precipice,” he’d instinctively jump to his death.

4. Ornithophobia

Traumatic childhood experiences involving birds—like, say, getting chased by a goose—can give birth to a lifelong fear of feathered critters. For Lucille Ball, they always reminded her of her father's untimely death when she was just a toddler: As her mother was delivering the horrible news, a couple of sparrows gathered by the kitchen windowsill.

“I’ve been superstitious about birds ever since,” Ball wrote in her autobiography. “I don’t have a thing about live birds, but pictures of birds get me. I won’t buy anything with a print of a bird, and I won’t stay in a hotel room with bird pictures or any bird wallpaper.”

5. Ailurophobia

Lucy van Pelt (sort of) mentions ailurophobia in A Charlie Brown Christmas, although she bungles the nomenclature and tells Charlie Brown, "If you’re afraid of cats, you have ailurophasia." (The -phasia suffix generally refers to speech disorders, such as aphasia.) That being said, the fear of cats is a phenomenon that goes by many names, including gatophobia and felinophobia.

Rumor has it that Napoleon Bonaparte and lots of other famous conquerors were terrified of kitties. In Bonaparte’s case, the allegations are probably false; according to historian Katharine MacDonogh, “No record exists of Napoleon either liking or hating cats.” She thinks this myth reflects the long-standing cultural belief that our feline friends wield supernatural insights. “Cats have been endowed with a magical ability to detect the overweening ambitions of dictators, many of whom have consequently been accused of ailurophobia on the flimsiest evidence,” MacDonogh wrote in her book Reigning Cats And Dogs: A History of Pets At Court Since The Renaissance.

6. Alektorophobia

Chickens, hens, and roosters put alektorophobes on edge. A rare type of ornithophobia, this fowl-based fear is no laughing matter. One 2018 case study reported on a 32-year-old man who would experience heart palpitations, a sudden dryness of the mouth, and uncomfortable feelings in his chest upon seeing a neighbor’s hen. It was ultimately determined that the man's phobia was the result of a frightening childhood encounter he’d had with a rooster.

7. Ostraconophobia

“I have a lobster phobia, I don’t know why. I just don’t like them,” NASCAR driver Denny Hamlin told the press in 2017. “I cannot eat dinner if someone beside me is eating lobster.” The admission came just after Hamlin had won the Monster Energy NASCAR Cup Series. Why did that matter? Because the event took place at the New Hampshire Motor Speedway, where race-winners are customarily rewarded with giant, live lobsters. But when somebody approached Hamlin with a 44-pounder, he tried to flee the stage. Ostraconophobia, or fear of shellfish, can also manifest itself as a fear of crabs or oysters. The majority of people who deal with this phobia develop it after getting sick from the shellfish that makes them feel uneasy.

8. Ichthyophobia

Ichthyophobia is a bit of an umbrella term that covers an irrational disdain of fish in a variety of situations. It can refer to the fear of being around live fish, the fear of eating dead ones, or the fear of touching them. A common version of that first anxiety is galeophobia, the widespread fear of sharks. And then there are those who are disturbed (and sometimes even physically sickened) by the sight or smell of fishy entrees; these ichthyophobes may take pains to avoid supermarkets with large seafood aisles.

9. Musophobia

Among the British adults who participated in a 2017 phobia survey, more than 25 percent reported that they were afraid of mice. By comparison, only 24 percent said they dreaded sharp needles or airplanes. In addition to disliking mice, musophobes are often afraid of other rodents, such as hamsters and rats.

10. Equinophobia

Sigmund Freud once wrote a case study on a boy who was terrified of horses. At age 4, Herbert Graf—referred to as “Little Hans” in the paper—had seen an overloaded work horse crumble to the ground in a heap. Following the traumatic incident, Hans became easily spooked while in the presence of horses; just the sound of clopping hooves was enough to trigger his anxiety. As a result, Hans often refused to leave the house.

Little Hans eventually overcame his fears, but equinophobia is still with us today. Kansas City Chiefs safety Eric Berry developed it after being bitten by a pony at a petting zoo when he was a child. Unfortunately for Berry, one of the Chiefs’s mascots is a live pinto horse named Warpaint. As former teammate Derrick Johnson told NFL Films, “He’s always watching for the horse, making sure the horse doesn’t look at him or do something crazy.” Berry has taken steps to overcome his horse phobia, though; in fact, he has even worked up the courage to (briefly) pet Warpaint.

11. Cynophobia

If you’re afraid of snakes, at least you’ll (probably) never have to worry about some coworker bringing his pet anaconda into the office. Cynophobes aren’t so lucky. Defined as the “fear of dogs,” cynophobia is an especially challenging animal phobia to have because, well, puppers are everywhere. Cynophobic people may go out of their way to avoid parks and tend to feel uncomfortable in neighborhoods where loud pooches reside.

As with ornithophobia, the fear of canines often stems from a traumatic childhood event. Therapists have found that, for many patients, the best way to overcome this aversion is through controlled exposure; spending quality time with a well-trained dog under a supervisor’s watchful eye can work wonders.
