Animal Kingdom Kleptos: 7 Species That Steal

Humanity, you’re not alone in harboring a criminal element. Some animals have developed kleptoparasitic tendencies, which means they’re willing to steal food that’s been collected by another animal. Other animals are just outright sneaky, and will take anything that’s there for the snatching. Here are seven animal kleptos.

1. Bumblebee

It’s a tenet of nature that the typical bee feeds off the nectar of a plant for pollinating that plant, but some bees are too rude to play by the rules. Bees who’ve evolved with short tongues and thus can’t reach for the sweet nectar have learned to carve holes into the side of a flower in order to reach their reward. This phenomenon, first observed by Charles Darwin, gets a bee nectar without the bee pollinating the plant. More cannily, there’s evidence suggesting that bees aren’t born behaving this way—they learn how to thieve from other bees, a sad sign that bee society is being overrun by hoodlums.

2. Sperm whale

Grace is not a word instinctively associated with the sperm whale, given its hulking size. But fishermen complaining about their depleted hauls were shocked to record video of a sperm whale nimbly plucking a savory sablefish off the end of a line with its tongue, leaving barely a trace of evidence. Whales will use their sonar to track a fishing boat so they can slip in when the line is heaviest, and are advanced enough to differentiate between the tastiest catches. Of course, there’s a school of thought stating that it’s really the fishermen who are stealing from the ocean, and that the spermwhale is just correcting the balance of nature. Fight the power, whale!

3. Skua

A moniker like “avian pirate” has a heavy reputation, and the skua’s plundering tactic isn’t quite as charming as Johnny Depp’s. The skua will gang up on smaller seabirds such as the guillemot and kittiwake, forcing them to give up a recently acquired kill. Sometimes, that means scaring a mark into vomiting up the contents of its stomach; other times, that means spearing another bird out of the air over and over until it drops its catch. It’s not very nice, but no skua ever claimed it was here to make friends.

4. Hyena

Despite their depiction in The Lion King as skeevy flea-bags all too excited to endorse a false king, hyenas are wily hunters who can survive on anything and travel in large matriarchally organized clans. And they're savvy enough to snatch a fresh kill from animals who haven't learned to do their hunting when the hyena is asleep. It's payback from when larger cats stole their own spoils, a natural part of the animal kingdom's adaptive ecosystem. Don't believe everything you see, even if it's a Disney classic.

5. Magpie

Type “magpie stealing” into YouTube and a number of videos will pop up showing a string of eclectic thefts: tea light candles, coathangers, lighters, cigarettes, cookies, dog food, raccoon bait, and more. An Englishwoman even thought she’d lost her engagement ring until it turned up three years later in a magpie’s nest. Though superstition states that magpies prefer shiny objects, they’re willing to take whatever—a characteristic that’s perhaps enabled by a prodigious intelligence rating amongst the highest of all animals. Hence the taken tea light candles—clearly, that magpie was smart enough to recognize how much they would improve the mood lighting for a party.

6. Burrowing owl

Pity the poor prairie dog, which does so much work building a habitat only to see it taken over by a stranger proclaiming a very simple edict: your home or your life. The burrowing owl prefers to occupy a burrow that’s already been dug out by a prairie dog, and is willing to eat those who aren’t naturally submissive to its bullying. It’s a truly parasitic relationship, as there’s evidence showing that burrowing owl populations are drastically depleted in areas where prairie dogs have been targeted for extermination. “I can’t quit you” isn’t the greatest consolation during the eviction process, but it’s better than nothing.

7. Bdelloid rotifers

A lack of sex will lead a person toward some pretty erratic behavior; still, the the bdelloid rotifer takes asexuality to another level. The microscopic animal has been a female-only species for 80 million years, but they’ve nevertheless diversified into hundreds of other subspecies by absorbing the DNA of fungi, bacteria, algae, and whatever else is small enough to consume at the planktonic level. That allows them to develop different traits to help survive in varied environments, since monastic perseverance is at least something in lieu of a hot date.

While dining out, you may have noticed (but perhaps didn’t question) some unusual features—like prices missing dollar signs, or burgers served on plates that could accommodate a baby cow.

These aren’t just arbitrary culinary decisions, as the SciShow’s Hank Green explains in the video below. Restaurants use all kinds of psychological tricks to make you spend more money, ranging from eliminating currency symbols (this makes you think less about how much things cost) to plating meals on oversize dinnerware (it makes you eat more). As for the mouthwatering language used to describe food—that burger listed as a "delectable chargrilled extravagance," for example—studies show that these types of write-ups can increase sales by up to 27 percent.

Learn more psychological tricks used by restaurants (and how to avoid falling for them) by watching the video below. (Or, read our additional coverage on the subject.)

8 of the Weirdest Gallup Polls

Born in Jefferson, Iowa on November 18, 1901, George Gallup studied journalism and psychology, focusing on how to measure readers’ interest in newspaper and magazine content. In 1935, he founded the American Institute of Public Opinion to scientifically measure public opinions on topics such as government spending, criminal justice, and presidential candidates. Although he died in 1984, The Gallup Poll continues his legacy of trying to determine and report the will of the people in an unbiased, independent way. To celebrate his day of birth, we compiled a list of some of the weirdest, funniest Gallup polls over the years.

1. THREE IN FOUR AMERICANS BELIEVE IN THE PARANORMAL (2005)

According to this Gallup poll, 75 percent of Americans have at least one paranormal belief. Specifically, 41 percent believe in extrasensory perception (ESP), 37 percent believe in haunted houses, and 21 percent believe in witches. What about channeling spirits, you might ask? Only 9 percent of Americans believe that it’s possible to channel a spirit so that it takes temporary control of one's body. Interestingly, believing in paranormal phenomena was relatively similar across people of different genders, races, ages, and education levels.

2. ONE IN FIVE AMERICANS THINK THE SUN REVOLVES AROUND THE EARTH (1999)

In this poll, Gallup tried to determine the popularity of heliocentric versus geocentric views. While 79 percent of Americans correctly stated that the Earth revolves around the sun, 18 percent think the sun revolves around the Earth. Three percent chose to remain indifferent, saying they had no opinion either way.

3. 22 PERCENT OF AMERICANS ARE HESITANT TO SUPPORT A MORMON (2011)

Gallup first measured anti-Mormon sentiment back in 1967, and it was still an issue in 2011, a year before Mormon Mitt Romney ran for president. Approximately 22 percent of Americans said they would not vote for a Mormon presidential candidate, even if that candidate belonged to their preferred political party. Strangely, Americans’ bias against Mormons has remained stable since the 1960s, despite decreasing bias against African Americans, Catholics, Jews, and women.

4. MISSISSIPPIANS GO TO CHURCH THE MOST; VERMONTERS THE LEAST (2010)

This 2010 poll amusingly confirms the stereotype that southerners are more religious than the rest of the country. Although 42 percent of all Americans attend church regularly (which Gallup defines as weekly or almost weekly), there are large variations based on geography. For example, 63 percent of people in Mississippi attend church regularly, followed by 58 percent in Alabama and 56 percent in South Carolina, Louisiana, and Utah. Rounding out the lowest levels of church attendance, on the other hand, were Vermont, where 23 percent of residents attend church regularly, New Hampshire, at 26 percent, and Maine at 27 percent.

5. ONE IN FOUR AMERICANS DON’T KNOW WHICH COUNTRY AMERICA GAINED INDEPENDENCE FROM (1999)

Although 76 percent of Americans knew that the United States gained independence from Great Britain as a result of the Revolutionary War, 24 percent weren’t so sure. Two percent thought the correct answer was France, 3 percent said a different country (such as Mexico, China, or Russia), and 19 percent had no opinion. Certain groups of people who consider themselves patriotic, including men, older people, and white people (according to Gallup polls), were more likely to know that America gained its independence from Great Britain.

6. ONE THIRD OF AMERICANS BELIEVE IN GHOSTS (2000)

This Halloween-themed Gallup poll asked Americans about their habits and behavior on the last day of October. Predictably, two-thirds of Americans reported that someone in their house planned to give candy to trick-or-treaters and more than three-quarters of parents with kids reported that their kids would wear a costume. More surprisingly, 31 percent of American adults claimed to believe in ghosts, an increase from 1978, when only 11 percent of American adults admitted to a belief in ghosts.

7. 5 PERCENT OF WORKING MILLENNIALS THRIVE IN ALL FIVE ELEMENTS OF WELL-BEING (2016)

This recent Gallup poll is funny in a sad way, as it sheds light on the tragicomic life of a millennial. In this poll, well-being is defined as having purpose, social support, manageable finances, a strong community, and good physical health. Sadly, only 5 percent of working millennials—defined as people born between 1980 and 1996—were thriving in these five indicators of well-being. To counter this lack of well-being, Gallup’s report recommends that managers promote work-life balance and improve their communication with millennial employees.

8. THE WORLD IS BECOMING SLIGHTLY MORE NEGATIVE (2014)

If you seem to feel more stress, sadness, anxiety, and pain than ever before, Gallup has the proof that it’s not all in your head. According to the company’s worldwide negative experience index, negative feelings such as stress, sadness, and anger have increased since 2007. Unsurprisingly, people living in war-torn, dangerous parts of the word—Iraq, Iran, Egypt, Syria, and Sierra Leone—reported the highest levels of negative emotions.
