9 Feathery Facts About Peacocks

With its massive tail and iridescent colors, this bird has long fascinated its human observers—and we’re still learning its secrets. For example, a study recently published in The British Journal of Animal Behaviour says that when a peacock fans its ornamented train for the ladies during mating season, its feathers quiver, emitting a low-frequency sound inaudible to human ears. Depending on whether they want to attract females from far away or up close, they can change the sound by shaking different parts of their feathers. (They’re not the only animals that create infrasonic sounds. Elephants produce them with their vocal cords, most likely to communicate over long distances.) Here are a few other interesting facts about these impressive birds.

1. Only the males are actually “peacocks.”

The collective term for these birds is “peafowl.” The males are “peacocks” and the females are “peahens.” The babies are called “peachicks.”

2. A family of peafowl is called a “bevy.”

A group of the birds is also sometimes called an “ostentation,” a “muster,” or even a “party.”

3. They’re not born with their fancy tail feathers.

The male peachicks don’t start growing their showy trains until about age three. In fact, it’s hard to tell the sex of a peachick because they’re nearly identical to their mothers. At around six months, the males will begin to change color [PDF].

4. They don’t have to be killed for their feathers.

Luckily, the peacocks shed their train every year after mating season, so the feathers can be gathered and sold without the birds coming to any harm. The average lifespan of a peacock in the wild is about 20 years.

5. They can fly, despite their massive trains.

A peacock’s tail feathers can reach up to six feet long and make up about 60 percent of its body length. Despite these odd proportions, the bird flies just fine, if not very far.

6. There are all-white peafowl.

Thanks to selective breeding, it’s common for captive peafowl to buck the iridescent trend for all white feathers. This is called leucism, and it’s due to a genetic mutation that causes loss of pigmentation. These peafowl are often mistaken for being albino, but instead of having red eyes, animals with leucism retain their normal eye color.

7. Peacocks were a delicacy in medieval times.

The birds were plucked, roasted and then re-dressed in their feathers to appear in their original live state on the dinner table. Here’s the presentation instructions from one recipe:

“wynde the skyn
wit the fethurs and the taile abought
the body, And serue him forthe as he
were a-live”

The birds may have looked beautiful, but they reportedly tasted terrible. “It was tough and coarse, and was criticized by physicians for being difficult to digest and for generating bad humors,” writes Melitta Weiss Adamson in her book Food in Medieval Times.

8. They can fake it.

These birds aren’t just nice to look at, they’re also clever, according to one recent study.

When peacocks mate with peahens, they give out a loud “copulatory call.” Canadian researchers Roslyn Dakin and Robert Montgomerie discovered that the birds can “fake” this call to attract more females. As the BBC’s Ella Davies put it, “By pretending they are mating when they are not, the birds could convince females they are more sexually active—and therefore genetically fitter—than their rivals.”

In fact, one-third of the calls heard by researchers were fake, and the birds that made them scored the most hookups. Sneaky, sneaky.

9. Their feathers are covered in tiny crystal-like structures.

What makes the peacock’s feathers so brilliant? Microscopic “crystal-like structures” that reflect different wavelengths of light depending on how they’re spaced, resulting in bright fluorescent colors. Hummingbirds and shimmering butterflies have mastered a similar visual effect on their own wings.

Sploot 101: 12 Animal Slang Words Every Pet Parent Should Know
iStock

For centuries, dogs were dogs and cats were cats. They did things like bark and drink water and lay down—actions that pet parents didn’t need a translator to understand.

Then the internet arrived. Scroll through the countless Facebook groups and Twitter accounts dedicated to sharing cute animal pictures and you’ll quickly see that dogs don’t have snouts, they have snoots, and cats come in a colorful assortment of shapes and sizes ranging from smol to floof.

Pet meme language has been around long enough to start leaking into everyday conversation. If you're a pet owner (or lover) who doesn’t want to be out of the loop, here are the terms you need to know.

1. SPLOOT

You know your pet is fully relaxed when they’re doing a sploot. Like a split but for the whole body, a sploot occurs when a dog or cat stretches so their bellies are flat on the ground and their back legs are pointing behind them. The amusing pose may be a way for them to take advantage of the cool ground on a hot day, or just to feel a satisfying stretch in their hip flexors. Corgis are famous for the sploot, but any quadruped can do it if they’re flexible enough.

2. DERP

Unlike most items on this list, the word derp isn’t limited to cats and dogs. It can also be a stand-in for such expressions of stupidity as “duh” or “dur.” In recent years the term has become associated with clumsy, clueless, or silly-looking cats and dogs. A pet with a tongue perpetually hanging out of its mouth, like Marnie or Lil Bub, is textbook derpy.

3. BLEP

If you’ve ever caught a cat or dog poking the tip of its tongue past its front teeth, you’ve seen a blep in action. Unlike a derpy tongue, a blep is subtle and often gone as quickly as it appears. Animal experts aren’t entirely sure why pets blep, but in cats it may have something to do with the Flehmen response, in which they use their tongues to “smell” the air.

4. MLEM

Mlems and bleps, though very closely related, aren’t exactly the same. While blep is a passive state of being, mlem is active. It’s what happens when a pet flicks its tongue in and out of its mouth, whether to slurp up water, taste food, or just lick the air in a derpy fashion. Dogs and cats do it, of course, but reptiles have also been known to mlem.

5. FLOOF

Some pets barely have any fur, and others have coats so voluminous that hair appears to make up most of their bodyweight. Dogs and cats in the latter group are known as floofs. Floofy animals will famously leave a wake of fur wherever they sit and can squeeze through tight spaces despite their enormous mass. Samoyeds, Pomeranians, and Persian cats are all prime examples of floofs.

6. BORK

According to some corners of the internet, dogs don’t bark, they bork. Listen carefully next time you’re around a vocal doggo and you won’t be able to unhear it.

7. DOGGO

Speaking of doggos: This word isn’t hard to decode. Every dog—regardless of size, floofiness, or derpiness—can be a doggo. If you’re willing to get creative, the word can even be applied to non-dog animals like fennec foxes (special doggos) or seals (water doggos). The usage of doggo saw a spike in 2016 thanks to the internet and by the end of 2017 it was listed as one of Merriam-Webster’s “Words We’re Watching.”

8. SMOL

Some pets are so adorably, unbearably tiny that using proper English to describe them just doesn’t cut it. Not every small pet is smol: To earn the label, a cat or dog (or kitten or puppy) must excel in both the tiny and cute departments. A pet that’s truly smol is likely to induce excited squees from everyone around it.

9. PUPPER

Like doggo, pupper is self-explanatory: It can be used in place of the word puppy, but if you want to use it to describe a fully-grown doggo who’s particularly smol and cute, you can probably get away with it.

10. BOOF

We’ve already established that doggos go bork, but that’s not the only sound they make. A low, deep bark—perhaps from a dog that can’t decide if it wants to expend its energy on a full bark—is best described as a boof. Consider a boof a warning bark before the real thing.

11. SNOOT

Snoot was already a dictionary-official synonym for nose by the time dog meme culture took the internet by storm. But while snoot is rarely used to describe human faces today, it’s quickly becoming the preferred term for pet snouts. There’s even a wholesome viral challenge dedicated to dogs poking their snoots through their owners' hands.

12. BOOP

Have you ever seen a dog snoot so cute you just had to reach out and tap it? And when you did, was your action accompanied by an involuntary “boop” sound? This urge is so universal that boop is now its own verb. Humans aren’t the only ones who can boop: Search the word on YouTube and treat yourself to hours of dogs, cats, and other animals exchanging the love tap.

Carnivorous Hammerhead Flatworms Are Invading France

It’s no hammerhead shark, but the hammerhead flatworm has become a real menace in France. Or at least a menace to earthworms, as Earther reports.

Believed to be an invasive species from Asia, the hammerhead flatworm was only recently recorded in France, as is documented in a new study (titled "Giant worms chez moi!") published in the journal PeerJ. However, based on reports, photographs, and videos sent in by citizens across the country, scientists determined the pests have gone undetected for nearly 20 years. This came as a shock, especially because the worms can measure more than a foot in length.

In recent years, three species of the carnivorous worm have quietly taken over French gardens and have even been spotted in metropolitan areas. Some species immobolize their prey with tetrodotoxin, the same powerful neurotoxin that makes pufferfish so poisonous. The worms secrete digestive enzymes, allowing them to dissolve earthworms and slugs their size.

Jean-Lou Justine, co-author of the study, says their eating habits are a concern. "Earthworms are a major component of the soil biomass and a very important element in the ecology of soils," Justine tells Earther. "Any predator which can diminish the populations of earthworms is thus a threat to soil ecology."

Archie Murchie, an entomologist who was not involved in the study, told The Washington Post that the worms will continue to spread in step with global trade. The worms were also seen in overseas French territories, including one worm with a blue-green hue that is probably a newly detected species, Murchie tells the newspaper.
