10 Amazing Facts About 10 Birds

3 min read

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.

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.
