Meet the Owl that Fishes with Feces

Back in the early 2000s, ornithologist Doug Levey was teaching a course at the University of Florida when he had a weird idea about poop. 

He and some of his students were on a field trip observing burrowing owls—a tiny, long-legged species that makes its home in underground burrows. If you’ve seen photos of burrowing owls, you know they’re pretty cute. If you’ve seen them in the wild, you know they’re also pretty weird. Unlike most of their cousins, burrowing owls are active during the daytime, and spend most of their day standing around the entrances of their burrows doing what seems to be a whole lot of nothing. 

All of this standing around is done amid piles of dung, which the owls collect and arrange around their homes like bizarre lawn decorations. Cow dung. Horse dung. Dung from dogs, cats, antelope—you name it. If an animal shares territory with burrowing owls and poops, chances are the owls will take it home; they don’t seem to be picky about whose feces they’re collecting. But what do they do with all of it?

One of Levey’s students pointed out that there were lots of dung beetle parts scattered throughout the owls’ pellets, the masses of undigested food that some birds regurgitate. Levey quickly put two and two together. If you want to catch a dung beetle, he figured, you’d leave some dung out. Maybe the owls were using the poo piles as bait to lure in their prey. 

To test the idea, Levey and his beetle-spotting student Scot Duncan cleared all the burrows of two different owl populations of their dung, pellets, and beetle pieces. Then they went back and scattered cow dung around half of them and left the other half alone. A few days later, they collected the regurgitated pellets and prey remains from all the burrows and kept them for analysis. Then they repeated the experiment, this time switching the burrows that got fresh dung and those that didn’t get any. 

They found that the owls who had dung at their burrows ate much better than their dung-less neighbors; their pellets suggested that they consumed ten times as many beetles and six times as many different beetle species. 

While it might look like the owls are standing around doing nothing, they’re really fishing for beetles with some unconventional bait. 

It’s a fascinating bit of tool use, but no one can tell if the owls are consciously collecting the dung as bait, acting on instinct, or even bringing the dung home for another reason (like masking the odor of their eggs or chicks) and simply enjoying the beetle-luring effect as a bonus.

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

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.
