Happy Penguin Awareness Day! To celebrated, here are a few fun facts about these adorable tuxedoed birds.

1. All 17 species of penguins are found exclusively in the Southern Hemisphere.

2. Emperor Penguins are the tallest species, standing nearly 4 feet tall. The smallest is the Little Blue Penguin, which is only about 16 inches.

3. The fastest species is the Gentoo Penguin, which can reach swimming speeds up to 22 mph.

4. A penguin's striking coloring is a matter of camouflage; from above, its black back blends into the murky depths of the ocean. From below, its white belly is hidden against the bright surface.

5. Fossils place the earliest penguin relative at some 60 million years ago, meaning an ancestor of the birds we see today survived the mass extinction of the dinosaurs.

6. Penguins ingest a lot of seawater while hunting for fish, but a special gland behind their eyes—the supraorbital gland—filters out the saltwater from their blood stream. Penguins excrete it through their beaks, or by sneezing.

7. Unlike most birds—which lose and replace a few feathers at a time—penguins molt all at once, spending two or three weeks land-bound as they undergo what is called the catastrophic molt.

8. All but two species of penguins breed in large colonies of up to a thousand birds.

9. It varies by species, but many penguins will mate with the same member of the opposite sex season after season.

10. Similarly, most species are also loyal to their exact nesting site, often returning to the same rookery in which they were born.

11. Some species create nests for their eggs out of pebbles and loose feathers. Emperor Penguins are an exception: They incubate a single egg each breeding season on the top of their feet. Under a loose fold of skin is a featherless area with a concentration of blood vessels that keeps the egg warm.

12. In some species, it is the male penguin which incubates the eggs while females leave to hunt for weeks at a time. Because of this, pudgy males—with enough fat storage to survive weeks without eating—are most desirable.

13. Penguin parents—both male and female—care for their young for several months until the chicks are strong enough to hunt for food on their own.

14. If a female Emperor Penguin's baby dies, she will often "kidnap" an unrelated chick.

15. Despite their lack of visible ears, penguins have excellent hearing and rely on distinct calls to identify their mates when returning to the crowded breeding grounds.

16. The first published account of penguins comes from Antonio Pigafetta, who was aboard Ferdinand Magellan's first circumnavigation of the globe in 1520. They spotted the animals near what was probably Punta Tombo in Argentina. (He called them "strange geese.")

17. An earlier, anonymous diary entry from Vasco da Gama's 1497 voyage around the Cape of Good Hope makes mention of flightless birds as large as ducks.

18. Because they aren't used to danger from animals on solid ground, wild penguins exhibit no particular fear of human tourists.

19. Unlike most sea mammals—which rely on blubber to stay warm—penguins survive because their feathers trap a layer of warm air next to the skin that serves as insulation, especially when they start generating muscular heat by swimming around.

20. In the 16th century, the word penguin actually referred to great auks (scientific name: Pinguinus impennis), a now-extinct species that inhabited the seas around eastern Canada. When explorers traveled to the Southern Hemisphere, they saw black and white birds that resembled auks, and called them penguins. 

The Isle of Sark Needs a New Dairy Farmer, But You'll Have to Bring Your Own Cows

If you've ever dreamed of moving to a secluded island to become a farmer, the Isle of Sark is giving you the opportunity. Sark, located in England's Channel Islands, is seeking a dairy farmer to supply milk to the island's population of 500. The only catch is that job candidates must be ready to move there with their own herd of 25 to 35 cows, Atlas Obscura reports.

Sark is a 3-mile long, mile-and-a-half wide island with green pastures, rocky cliffs, and no cars or street lamps. The only way to get there is by boat or one of the ferries that leaves from the nearby Jersey and Guernsey islands.

The last time the island had a dairy farmer was 2017. That year, farmer Christopher Nightingale shut down his business due to issues with costs and land instability. The Isle of Sark held onto feudalism long after the rest of Europe abandoned it, and though the practice technically ended in 2008, it hasn't died completely. Sometimes this works to the community's advantage, like when Nazis invaded in 1940, but it also means that farmers must lease their land for short periods rather than own it.

If you're willing to trade your right to own property for idyllic island living, Sark's dairy farmer gig maybe the perfect fit for you. The island is looking for someone, or a couple, with lots of dairy farming experience, and a herd of Jersey or Guernsey cows, which are native to the Channel Islands.

7 Myths About Bats

Though in China bats are said to bring good luck, and ancient Egyptians believed they could cure an array of diseases, our feelings about bats are often negative. Perhaps these rumors started because bats are so mysterious—with their nocturnal flying and dank, dark habitats, they’re hard to study. But the world's only flying mammal isn't nearly as bad as our fears make it out to be. Keep reading for seven misconceptions, as well as explanations of what really goes on in the batcave.

1. Bats are totally blind.

Though we love to talk about things being "blind as a bat," bigger bats can see up to three times better than humans, according to Rob Mies, executive director of the Organization for Bat Conservation. Bat vision varies across species, but none are actually blind. In addition to working peepers, bats also use echolocation (emitting sound to navigate)—which means they probably have a better idea of where they're going than many of us.

2. Bats are flying rats.

Bats belong to the order Chiroptera, not Rodentia; they're actually more closely related to primates than they are to rodents. They also don't share behavior with rodents. For example, bats don't chew on wood, metal, or plastic, and usually aren't nuisances. In fact, bats eat pests, which brings us to …

3. Bats are annoying pests.

Quite the opposite! According to National Geographic, bats can eat up to a thousand insects in an evening. Their bug-eating prowess is so notable it carries economic importance. A recent study showed that bats provide "nontoxic pest-control services totaling $3.7 billion to $53 billion per year." Bats also pollinate plants and distribute seeds, and their droppings—called guano—are used as fertilizer.

4. Bats want to drink your blood.

Only three of the roughly 1200 existing bat species are vampire bats, and none of them live in the United States or Canada. Vampire bats don't even really drink blood—Mies says the feeding process is more like that of a mosquito. While mosquitos will take blood from humans, though, vampire bats primarily feed on cattle. Fun fact: a medication called draculin is currently being developed from bats' saliva, which has unique anti-blood-clotting properties.

5. Bats will fly into your hair and build a nest.

An old myth claims that bats fly into hair, get stuck, and build nests. While it's possible this rumor started to deter young women from going out at night, bats do sometimes swoop around people’s heads. The reason isn't because they're shopping for a new home, however: our bodies attract insects, and bats are after their next snack. So don't worry—your spectacular updo is safe. In fact, bats don't build nests at all: Instead, they find shelter inside existing structures. Caves, trees, walls, and ceilings are favorites, as are rafters of buildings

6. Bats always hang upside down.

Contrary to the popular image, bats don't don't necessarily dangle pointing downward. According to Dr. Thomas Kunz from Boston University, bats are frequently horizontal when roosting in small crevices, not vertical.

7. Bats will attack you and give you rabies.

Nope. Shari Clark, president of the Florida Bat Conservancy, says that statistically bats contract rabies much less frequently than other mammals. And if they do get rabies, it manifests differently than in raccoons or foxes. Rabies-infected bats become paralyzed and can't fly or roost. This means that as long as you stay away from bats on the ground that are behaving weirdly, you're pretty much in the clear. Phew.
