Amazing & Weird Facts About 10 Birds...
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.
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.
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.
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.
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.”
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.
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.
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.
