15 Mysterious Facts About Owls

Owls are enigmatic birds, by turns mysterious, lovable, or spooky, depending on who you ask. With over 200 species living on every continent except Antarctica, owls have super-tuned senses that help them hunt prey all over the world. And they’re pretty darn cute, too.

1. OWLS CAN TURN THEIR HEADS ALMOST ALL THE WAY AROUND—BUT NOT QUITE.

It’s a myth that owls can rotate their heads 360 degrees. The birds can actually turn their necks 135 degrees in either direction, which gives them 270 degrees of total movement. According to scientists, bone adaptations, blood vessels with contractile reservoirs, and a supporting vascular network allow the owls to turn their heads that far without cutting off blood to the brain.

2. OWLS HAVE FAR-SIGHTED, TUBULAR EYES. 

Instead of spherical eyeballs, owls have "eye tubes" that go far back into their skulls—which means their eyes are fixed in place, so they have to turn their heads to see. The size of their eyes helps them see in the dark, and they're far-sighted, which allows them to spot prey from yards away. Up close, everything is blurry, and they depend on small, hair-like feathers on their beaks and feet to feel their food.

3. THEY HAVE SUPER-POWERED HEARING. 

Owls are capable of hearing prey under leaves, plants, dirt, and snow. Some owls have sets of ears at different heights on their heads, which lets them locate prey based on tiny differences in sound waves. Other owls have flat faces with special feathers that focus sound, essentially turning their faces into one big ear. (The “ear tufts” on some owls are feathers.)

4. OWL FLIGHT IS SILENT.

Unlike most birds, owls make virtually no noise when they fly. They have special feathers that break turbulence into smaller currents, which reduces sound. Soft velvety down further muffles noise.

5. OWLS SWALLOW PREY WHOLE, THEN BARF UP THE CARCASS. 

Getting killed by an owl is gruesome. First the owl grabs the prey and crushes it to death with its strong talons. Then, depending on the size, it either eats the prey whole or rips it up. The owl’s digestive tract processes the body, and the parts that can’t be digested, like fur and bones, are compacted into a pellet, which the owl later regurgitates. Sometimes, those pellets are collected for kids to dissect in school.

6. THEY SOMETIMES EAT OTHER OWLS. 

Not only do owls eat surprisingly large prey (some species, like the eagle owl, can even grab small deer), they also eat other species of owls. Great horned owls, for example, will attack the barred owl. The barred owl, in turn, sometimes eats the Western screech-owl. In fact, owl-on-owl predation may be a reason why Western screech-owl numbers have declined.

7. OWLS FEED THE STRONGEST BABIES FIRST.

As harsh as it sounds, the parents always feed the oldest and strongest owlet before its sibling. This means that if food is scarce, the youngest chicks will starve. After an owlet leaves the nest, it often lives nearby in the same tree, and its parents still bring it food. If it can survive the first winter on its own, its chances of survival are good.

8. THEY'RE MASTERS OF CAMOUFLAGE. 

Many owls sleep in broad daylight, but the colors and markings on their feathers—like the African Scops Owl, above—let them blend in with their surroundings.

9. SOMETIMES THEY MAKE A TERRIFYING HISSING NOISE. 

Aside from hooting, owls make a variety of calls, from screeches to whistles to squeaks. The barn owl hisses when it feels threatened, which sounds like something from a nightmare.

10. ELF OWLS LIVE IN CACTI.

The smallest owl is the elf owl, which lives in the southwestern United States and Mexico. It will sometimes make its home in the giant saguaro cactus, nesting in holes made by other animals. However, the elf owl isn’t picky and will also live in trees or on telephone poles.

11. BURROWING OWLS TAKE OVER PRAIRIE DOG TOWNS—AND HUNT WITH POOP.

The long-legged burrowing owl lives in South and North America. One of the few owls that is active during the daytime, it nests in the ground, moving into tunnels excavated by other animals such as prairie dogs. They’ll also dig their own homes if necessary. Then, they'll surround the entrances to their burrows with dung and "sit at the burrow entrance all day long and it looks like they're doing nothing," University of Florida zoologist Douglas Levey told National Geographic. But they're not doing nothing: They're fishing. The poop is bait for dung beetles, one of the owls' favorite types of prey. "Everybody who studies burrowing owls knows they bring dung back to their burrows, and they know that burrowing owls eat a lot of dung beetles. But nobody had put two and two together," Levey, co-author of a 2004 study announcing the behavior, said.

12. OWLS ARE NATURAL PEST CONTROL FOR FARMERS. 

Owls eat a lot of rodents. A single barn owl family will eat 3000 rodents in a four-month breeding cycle. One owl can eat 50 pounds of gophers in a year. Many farmers are installing owl nesting boxes in the hopes that owls will clean out pests like gophers and voles from their land. This natural form of pest control is safer and cheaper than using poison, and it’s better for the owls too. Many owls die each year from eating rodents that have been poisoned.

13. OWLS WERE ONCE A SIGN OF VICTORY IN BATTLE ... 

In ancient Greece, the Little Owl was the companion of Athena, the Greek goddess of wisdom, which is one reason why owls symbolize learning and knowledge. But Athena was also a warrior goddess and the owl was considered the protector of armies going into war. If Greek soldiers saw an owl fly by during battle, they took it as a sign of coming victory. 

14. ... AND A SYMBOL OF DEATH. 

From ancient times on, owls have been linked with death, evil, and other superstitions. Many cultures saw owls as a sign of impending death. For example, an owl was said to have predicted the death of Julius Caesar. They’ve also been associated with witches and other so-called evil beings. While this may sound like Halloween fun, many cultures still have superstitions about owls and in some places, owls are killed based on these beliefs.

15. OWLS AND HUMANS GENERALLY GET ALONG.

Owls have been popular since ancient times. They show up in Egyptian hieroglyphs and the 30,000-year-old cave paintings in France. Falconers have used owls since the Middle Ages, although not as commonly as other birds. Today, we still love owls. Though it’s illegal to keep them as pets in the United States, they’re intelligent and sociable. (Most of the time, anyway—owls can attack humans when feeling threatened.) In Japan, there are even owl cafés, where you can hang out with owls while drinking tea. 

Hundreds of Kangaroos Roam the Green at This Australian Golf Course

Anglesea Golf Club has all the makings of a regular golf club: an 18-hole golf course, a mini golf course, a driving range, a clubhouse, and a bistro. But the kangaroo mobs that hop around the holes add an element of surprise to your otherwise leisurely round of one of the slowest games in sports.

According to Thrillist, the kangaroos have been a mainstay for years, and the club started giving tours a few years ago to ensure visitors could observe them in the safest way possible. For about 25 minutes, a volunteer tour guide will drive a golf cart with up to 14 passengers around the course, sharing fun facts about kangaroos and stopping at opportune locations for people to snap a few photos of the marsupials, which are most active in late afternoon and early morning. Kangaroos are friendly creatures, but Anglesea’s website reminds visitors that “they can also be quite aggressive if they feel threatened.”

Post-graduate students and academic staff from Melbourne University’s zoology department have been researching Anglesea’s kangaroo population since 2004, and some of the animals are marked with collar and ear tags so the researchers can track movement, growth, survival, and reproduction patterns throughout their life cycle.

One of the reasons kangaroos have continued to dwell on land so highly trafficked by people is because of the quality of the land itself, National Geographic reports. The golf course staff regularly sprinkles nitrogen fertilizer all over the green, which makes the grass especially healthy.

10 Surprising Facts About Shoebill Storks

Shoebill storks have been called the world’s most terrifying bird (though the cassowary might disagree). These stately wading birds stalk the marshes of South Sudan, Uganda, and elsewhere in tropical East Africa, snatching up prey with their unique, immediately recognizable bills. But there are a lot of misconceptions about shoebill storks—the first being that they're not actually storks. Here are some more surprising facts.

1. Shoebill storks could win staring contests.

Shoebills live in the vast wetlands of the Nile watershed in eastern Africa. You really can’t mistake them for any other bird: They grow 4 to 5 feet tall, have bluish-gray plumage and an 8-plus-foot wingspan, and their bill, which takes up a majority of their face, looks like a huge Dutch wooden clog. Shoebills can stand virtually motionless for hours with their bills held down against their necks. Complemented by their golden eyes, the posture affects a very convincing death stare.

2. Shoebills may be more closely related to pelicans than storks.

Over the past couple of centuries, naturalists have debated where shoebills should appear on the Tree of Life. Some taxonomists said that the shoebill's syrinx, or vocal organ, resembled those of herons belonging to the family Pelecaniformes, which also includes ibises, pelicans, and boobies. Others countered that herons have specialized feathers than release a powdery down to help with preening, but shoebills didn’t have these feathers, so they must be storks belonging to the family Ciconiiformes. “There is, in fact, not the shadow of a doubt that it is either a heron or a stork; but the question is, which?” zoologist Frank Evers Beddard wrote in 1905. More recent studies on the shoebill's eggshell structure and DNA have supported its place among the Pelecaniformes.

3. Shoebills poop on themselves.

Shoebills practice urohydrosis, the effective—if revolting—habit of defecating on their legs to lower their body temperature. In fact, this characteristic confused taxonomists: In the past, some felt that the shoebill’s habit placed it within the family of true storks, since all true storks also use their own droppings to cool off.

4. European naturalists were introduced to shoebills in the 1840s.

A German diplomat and explorer named Ferdinand Werne was the first European to hear about the shoebill. On his expedition in Africa to find the source of the White Nile in 1840, Werne camped at Lake No, part of a 12,000-square-mile wetland called the Sudd in what is now South Sudan. Werne’s indigenous guides told him “that they had seen an extraordinary bird, as big as a big camel, with a bill like a pelican’s, though wanting a pouch,” according to a 1908 edition of The Avicultural Magazine.

About 10 years later, a collector named Mansfield Parkyns brought two shoebill skins to England, giving British zoologists their first look at the weird bird. At an 1851 meeting of the British Zoological Society, naturalist John Gould presented a description of the shoebill based on Parkyns’s specimens and gave it the scientific name Balaeniceps rex.

5. Shoebills are also called whale-headed storks.

Balaeniceps rex means “whale-head king,” evidently a reference to its bill shape resembling the head of a baleen whale (as well as a shoe). Other names for the shoebill include the boat-bill, bog-bird, lesser lechwe-eater (referring to the shoebill’s alleged taste for lechwe, or aquatic antelope), and abu markub, or “father of a slipper” in Arabic.

6. Shoebills love lungfish.

Yum, lungfish! These air-breathing, eel-like fish grow to more than 6 feet long and comprise the shoebill’s favorite food. Shoebills also chow down on actual eels, catfish, lizards, snakes, and baby crocodiles. To catch their prey, shoebills stand still in the water and wait for an unsuspecting fish to appear. Then, the bird swiftly “collapses” on its target, spreading its wings and diving down bill-first to ambush the fish. Then, with the fish in its mouth, it decapitates it by grinding the sharp edges of its bill together.

7. Shoebills really earned their fierce reputation.

Victorian photographers learned the hard way that shoebills could be as mean as they looked. “The shoebill is capable of inflicting a very powerful bite,” 19th-century zoologist Stanley S. Flower wrote, “and is by no means a safe bird for a stranger ignorant of its ways to approach, a fact which we often have to impress on amateur photographers anxious to obtain ‘snap-shots’ of Balaeniceps at close quarters. It has been amusing to see how rapidly in some cases their enthusiasm has waned, when (as requested) confronted with the great bird screaming shrill defiance and crouching as if were about to spring, with gaping bill and half-spread wings.”

8. Shoebills have always been a rare curiosity at zoos.

In the 19th century, the Sudanese government made the shoebill a protected species, but that did not stop collectors from attempting to transport shoebills to zoos. Flower, then director of the Zoological Gardens in Giza, Egypt, brought three shoebills (along with four giraffes, nine antelopes, a lion, a leopard, three servals, two ostriches, two porcupines, an aardvark, five tortoises, a crocodile, and several other animals) on a train north from Khartoum to the gardens. The temperature rose to 118°F and the irritated shoebills barfed up their dinners. Their diet of fresh fish that Flower had ordered never materialized, so he resorted to feeding the birds canned shrimp. Miraculously, the birds arrived at the Zoological Gardens in one piece and survived in captivity for at least five years. Today, only a handful of zoos open to the public have shoebills, including the Prague Zoo in the Czech Republic, Pairi Daiza in Belgium, the San Diego Zoo Safari Park, and the Dallas World Aquarium.

9. Shoebills are worth thousands of dollars on the black market.

Shoebills rarely breed in captivity: In the last hundred years at least, only two chicks have hatched. In today’s zoos, all shoebills were either born there or were legally collected from the wild. Unfortunately, their scarcity and mystique have also made shoebills a sought-after bird for poachers in the illegal wildlife trade. According to Audubon magazine, private collectors in Dubai and Saudi Arabia will pay $10,000 or more for a live shoebill.

10. Shoebills are at risk of extinction.

The IUCN Redlist estimates between 3300 and 5300 mature shoebills live in the world today, and that number is decreasing. The iconic birds are threatened by a number of anthropogenic forces, including loss of their marshland habitat from farming, livestock ranching, oil and gas exploration, fires, pollution, and more. International wildlife groups and local conservationists are monitoring shoebill habitats in South Sudan, Uganda, Tanzania, and Zambia and patrolling the sites for poaching, but much more attention is needed to protect shoebills.
