From brilliantly colored hummingbirds to farting thrushes, birds are among the most beautiful and bizarre creatures on Earth. With over 9000 species, our fine feathered friends inhabit almost every inch of the planet, making their homes in the frozen expanses of Antarctica, the humid rainforests of South America, and every climate in between. Here are 15 amazing facts you might not know about 15 amazing bird species.

1. Ravens are great at mimicking human speech and sounds.

While ravens in the wild are unlikely to pick up human language, in captivity they can become quite talkative. Some ravens are even better than parrots at mimicking human speech, not to mention sounds from the human world like car engines revving or toilets flushing. In the wild, meanwhile, ravens sometimes imitate other animals, mimicking predators like wolves or foxes to attract them to tasty carcasses they're unable to break open on their own.

2. Ostriches have the largest eyes of any land animal.

Ostrich eyes are the largest of any animal that lives on land (though they can't rival some of the massive creatures that inhabit the depths of the sea). Approximately the size of a billiard ball, their eyes are actually bigger than their brains.

3. Cardinals like to cover themselves in ants.

Cardinals (along with several other bird species) sometimes cover themselves in crushed or living ants, smearing them over their feathers, or allowing living ants to crawl on them. While scientists still aren't sure what the purpose of "anting" is, some believe the birds use the formic acid secreted during their ant bath to help get rid of lice and other parasites.

4. Owls devour their prey whole.

When owls catch larger animals (raccoons and rabbits, for instance), they tear them up into more manageable, bite-size pieces. But, they've also been known to simply swallow smaller animals, from insects to mice, whole. Owls then regurgitate pellets full of indigestible elements of their meal like animal bones and fur.

5. Some ducks sleep with one eye open.

When they nap in groups, the ducks on the perimeter keep guard by sleeping with one eye open. While the other ducks sleep more deeply, those on the outside of the circle also keep one side of their brain awake, even as they doze, so that predators won’t be able to sneak up on them.

6. Kiwis are sometimes called "honorary mammals."

Native to New Zealand, kiwis are a bizarre, land-bound bird. Scientists, so mystified by the kiwi's strange properties—which include feathers that feel like hair, heavy bones filled with marrow, and nostrils on the tip of their nose (rather than on the base of their beak like most birds)—have sometimes called them "honorary mammals."

7. Most hummingbirds weigh less than a nickel.

Hummingbirds are incredibly lightweight. The average hummingbird is around 4 grams (one gram less than a nickel), while the smallest, the bee hummingbird, is closer to 1.6 grams, less than the weight of a penny. The largest member of the hummingbird family, meanwhile, is the aptly named giant hummingbird, which can get up to 24 grams—enormous for a hummingbird, but only equivalent to about a handful of loose change.

8. In ancient Greece, pigeons delivered the results of the Olympic games.

Believed to be the first domesticated bird, pigeons were used for millennia to deliver messages, including important military information, and the outcome of the early Olympic games. Though non-avian mail delivery has become more popular over time, pigeons were used as recently as World War II to carry select messages.

9. Parrots can learn to say hundreds of words.

While most parrots only learn around 50 words, some African grey parrots have been known to learn hundreds. Einstein, a brilliant African grey parrot at the Knoxville Zoo in Tennessee, can say around 200 words.

10. Swiftlet nests are a delicacy.

Some swiftlets, appropriately named Edible-nest swiftlets, build nests almost exclusively from their hardened saliva. The saliva nests are considered a delicacy in some countries—in China, they are most frequently used to make bird’s nest soup—and are one of the most expensive foods in the world, despite having little flavor and no real nutritional value.

11. Bassian thrushes find food by farting.

Worm-eating Bassian thrushes have been known to dislodge their prey from piles of leaves by directing their farts at them. The excretion of gas shifts the leaf-litter on the ground and apparently provokes worms to move around, revealing their location.

12. Woodpeckers hoard acorns.

Acorn woodpeckers store acorns by drilling holes in trees, fence posts, utility poles, and buildings, and depositing their nuts there. They have been known to store up to 50,000 acorns—each in its own tiny hole—in a single tree, called a "granary tree."

13. The unique black and white coloring of penguins works as camoflage.

While penguins might stand out on land, underwater their black and white coloring helps them stay hidden from both predators and prey. As they swim, their black backs blend in with the darker ocean water below them so that they're difficult to spot from above. Their white chests, meanwhile, help them blend in with the lighter, brighter surface of the water, so that from below, they're near-invisible. On land, meanwhile, their black backs may stand out sharply against the snowy landscape, but in most regions, the birds face so few predators on land, it's unnecessary to try to blend into the background.

14. Hoatzin chicks are born with claws on their wings.

Though they disappear after three months, young hoatzin (also known as "stink birds" for their unique stench) have two claws on each wing, which they can use to climb across tree branches or pull themselves out of water onto dry land. The claws also help chicks hide from predators: After jumping from their nest into the water below, the little hoatzin swim some distance, then pull themselves on land with their claws. When the coast is clear, they use their claws to climb up onto a tree branch.

15. Budgies catch each other's yawns.

Budgerigars, or budgies, a common parakeet, are the only bird species so far discovered who are susceptible to contagious yawning. While humans, dogs, chimps, lab rats, and a few other creatures have all been known to catch each other's yawns, budgies are the first non-mammal species observed exhibiting the behavior. Many scientists believe the unconscious, instinctual response may be a primitive way of showing empathy, or it might be a sign of group alertness.

You’ll Be Able to Buy Some of Fiona the Hippo’s Poop to Fertilize Your Garden

Fiona the hippo has come along way since she was born two months premature at the Cincinnati Zoo in 2017. Today, Fiona is happy and healthy, weighing in at more than 1200 pounds. A hippo that size makes a lot of excrement, and now Fiona fans can purchase some of it to fertilize their gardens, WLWT5 reports.

Fiona produces about 22 pounds of poop a day; just 7 pounds shy of her birth weight. Normally the dung would be sent to a landfill, but as part of its new zero-waste initiative, the Cincinnati Zoo is composting all of its animal waste into fertilizer. Much of it will be added to the zoo's own farm and gardens, but some will also be available to purchase from the zoo's gift shops and online store. The fertilizer will be made from the dung left behind by the hundreds of animals living at the zoo, including Fiona.

The Cincinnati Zoo bills itself as the greenest zoo in the country. In addition to recycling all of its animal waste into compost, it also aims to fill its animal habitats with recycled rain water and grow more food for its animals on its own farm [PDF]. For the zero-waste part of the plan, the zoo plans to repurpose two million pounds of animal feces each year using a combination of on-site and off-site composting.

The zoo is in the process of acquiring the necessary equipment to launch its waste composting program. When the time comes, Fiona will be ready to make her sizable contributions to the project.

The Disabled Chihuahua Puppy Who Befriended a Flightless Pigeon Now Has a Tiny Wheelchair

The only thing more heartwarming than an interspecies friendship between a Chihuahua that can’t walk and a pigeon that can’t fly is if the Chihuahua in question happened to own a very tiny wheelchair.

Earlier this month, The Mia Foundation, a nonprofit shelter for special needs animals in Rochester, New York, took to Facebook to share photos of Lundy, a two-month-old Chihuahua without mobility in his back legs, snuggling up with a flightless pigeon named Herman.

"I took Herman out of his playpen to give him some time out and I put him in a dog bed and then I had to tend to Lundy so I put Lundy in with him,” Sue Rogers, who runs the foundation with her husband, Gary, told WHEC. “They just looked really cute together, so I took some pictures and posted them to Facebook and the next morning it was crazy.”

After the post went viral, The Mia Foundation received more than $6000 in monetary donations—and a surprise gift for Lundy. New Hampshire-based pet mobility company Walkin’ Pets provided him with a Mini Walkin’ Wheels wheelchair, a two-wheeled harness meant for disabled animals that weigh between two and 10 pounds. According to a press release from Walkin’ Pets, the shelter had been worried that two-pound Lundy, who could probably fit in the palm of your hand, wouldn’t get the chance to run around with the help of a wheelchair until he grew quite a bit bigger.

Newly mobile and even cuter than before, Lundy is now waiting for a kind family to adopt him. Finding a forever home might take him away from his fine feathered friend, but Lundy and Herman’s bond won’t ever be forgotten: There’s now a book called Lundy and Herman that tells their story. A portion of the proceeds will be donated to the Mia Foundation, and you can order it for $20 here.
