10 Fascinating Facts About Ravens

Edgar Allan Poe knew what he was doing when he used the raven instead of some other bird to croak out “nevermore” in his famous poem. The raven has long been associated with death and dark omens, but the real bird is somewhat of a mystery. Unlike its smaller cousin the crow, not a lot has been written about this remarkable bird. Here are 10 fascinating facts about ravens.

1. Ravens are one of the smartest animals.

When it comes to intelligence, these birds rate up there with chimpanzees and dolphins. In one logic test, the raven had to get a hanging piece of food by pulling up a bit of the string, anchoring it with its claw, and repeating until the food was in reach. Many ravens got the food on the first try, some within 30 seconds. In the wild, ravens have pushed rocks on people to keep them from climbing to their nests, stolen fish by pulling a fishermen’s line out of ice holes, and played dead beside a beaver carcass to scare other ravens away from a delicious feast.

If a raven knows another raven is watching it hide its food, it will pretend to put the food in one place while really hiding it in another. Since the other ravens are smart too, this only works sometimes.

2. Ravens can imitate human speech.

In captivity, ravens can learn to talk better than some parrots. They also mimic other noises, like car engines, toilets flushing, and animal and birdcalls. Ravens have been known to imitate wolves or foxes to attract them to carcasses that the raven isn’t capable of breaking open. When the wolf is done eating, the raven gets the leftovers.

3. Europeans often saw ravens as evil in disguise.

Many European cultures took one look at this large black bird with an intense gaze and thought it was evil in the flesh … er, feather. In France, people believed ravens were the souls of wicked priests, while crows were wicked nuns. In Germany, ravens were the incarnation of damned souls or sometimes Satan himself. In Sweden, ravens that croaked at night were thought to be the souls of murdered people who didn’t have proper Christian burials. And in Denmark, people believed that night ravens were exorcized spirits, and you’d better not look up at them in case there was a hole in the bird’s wing, because you might look through the hole and turn into a raven yourself.

4. Ravens have been featured in many myths.

Cultures from Tibet to Greece have seen the raven as a messenger for the gods. Celtic goddesses of warfare often took the form of ravens during battles. The Viking god, Odin, had two ravens, Hugin (thought) and Munin (memory), which flew around the world every day and reported back to Odin every night about what they saw. The Chinese said ravens caused bad weather in the forests to warn people that the gods were going to pass by. And some Native American tribes worshipped the raven as a deity in and of itself. Called simply Raven, he is described as a sly trickster who is involved in the creation of the world.

5. Ravens are extremely playful.

The Native Americans weren’t far off about the raven’s mischievous nature. They have been observed in Alaska and Canada using snow-covered roofs as slides. In Maine, they have been seen rolling down snowy hills. They often play keep-away with other animals like wolves, otters, and dogs. Ravens even make toys—a rare animal behavior—by using sticks, pinecones, golf balls, or rocks to play with each other or by themselves. And sometimes they just taunt or mock other creatures because it’s funny.

6. Ravens do weird things with ants.

They lie in anthills and roll around so the ants swarm on them, or they chew the ants up and rub their guts on their feathers. The scientific name for this is called “anting.” Songbirds, crows, and jays do it too. The behavior is not well understood; theories range from the ants acting as an insecticide and fungicide for the bird to ant secretion soothing a molting bird’s skin to the whole performance being a mild addiction. One thing seems clear, though: anting feels great if you’re a bird.

7. Ravens use “hand” gestures.

It turns out that ravens make “very sophisticated nonvocal signals,” according to researchers. In other words, they gesture to communicate. A study in Austria found that ravens point with their beaks to indicate an object to another bird, just as we do with our fingers. They also hold up an object to get another bird’s attention. This is the first time researchers have observed naturally occurring gestures in any animal other than primates.

8. Ravens are adaptable.

Evolutionarily speaking, the deck is stacked in the raven’s favor. They can live in a variety of habitats, from snow to desert to mountains to forests. They are scavengers with a huge diet that includes fish, meat, seeds, fruit, carrion, and garbage. They are not above tricking animals out of their food—one raven will distract the other animal, for example, and the other will steal its food. They have few predators and live a long time: 17 years in the wild and up to 40 years in captivity.

9. Ravens show empathy for each other.

Despite their mischievous nature, ravens seem capable of feeling empathy. When a raven’s friend loses in a fight, they will seem to console the losing bird. They also remember birds they like and will respond in a friendly way to certain birds for at least three years after seeing them. (They also respond negatively to enemies and suspiciously to strange ravens.) Although a flock of ravens is called an “unkindness,” the birds appear to be anything but.

10. Ravens roam around in teenage gangs.

Ravens mate for life and live in pairs in a fixed territory. When their children reach adolescence, they leave home and join gangs, like every human mother’s worst nightmare. These flocks of young birds live and eat together until they mate and pair off. Interestingly, living among teenagers seems to be stressful for the raven. Scientists have found higher levels of stress hormones in teenage raven droppings than in the droppings of mated adults. It’s never easy being a teenage rebel.

Owning a Dog May Add Years to Your Life, Study Shows

We've said that having a furry friend can reduce depression, promote better sleep, and encourage more exercise. Now, research has indicated that caring for a canine might actually extend your lifespan.

Previous studies have shown that dog owners have an innate sense of comfort and increased well-being. A new paper published in Scientific Reports and conducted by Uppsala University in Sweden looked at the health records of 3.4 million of the country's residents. These records typically include personal data like marital status and whether the individual owns a pet. Researchers got additional insight from a national dog registry providing ownership information. According to the study, those with a dog for a housemate were less likely to die from cardiovascular disease or any other cause during the study's 12-year duration.

The study included adults 40 to 80 years old, with a mean age of 57. Researchers found that dogs were a positive predictor in health, particularly among singles. Those who had one were 33 percent less likely to die early than those who did not. Authors didn't conclude the exact reason behind the correlation: It could be active people are more likely to own dogs, that dogs promoted more activity, or that psychological factors like lowered incidences of depression might bolster overall well-being. Either way, having a pooch in your life could mean living a longer one.

Big Questions
Why Don't We Eat Turkey Tails?

Turkey sandwiches. Turkey soup. Roasted turkey. This year, Americans will consume roughly 245 million birds, with 46 million being prepared and presented on Thanksgiving. What we don’t eat will be repurposed into leftovers.

But there’s one part of the turkey that virtually no family will have on their table: the tail.

Despite our country’s obsession with fattening, dissecting, and searing turkeys, we almost inevitably pass up the fat-infused rear portion. According to Michael Carolan, professor of sociology and associate dean for research at the College for Liberal Arts at Colorado State University, that may have something to do with how Americans have traditionally perceived turkeys. Consumption was rare prior to World War II. When the birds were readily available, there was no demand for the tail because it had never been offered in the first place.

"Tails did and do not fit into what has become our culinary fascination with white meat," Carolan tells Mental Floss. "But also from a marketing [and] processor standpoint, if the consumer was just going to throw the tail away, or will not miss it if it was omitted, [suppliers] saw an opportunity to make additional money."

Indeed, the fact that Americans didn't have a taste for tail didn't prevent the poultry industry from moving on. Tails were being routed to Pacific Island consumers in the 1950s. Rich in protein and fat—a turkey tail is really a gland that produces oil used for grooming—suppliers were able to make use of the unwanted portion. And once consumers were exposed to it, they couldn't get enough.

“By 2007,” according to Carolan, “the average Samoan was consuming more than 44 pounds of turkey tails every year.” Perhaps not coincidentally, Samoans also have alarmingly high obesity rates of 75 percent. In an effort to stave off contributing factors, importing tails to the Islands was banned from 2007 until 2013, when it was argued that doing so violated World Trade Organization rules.

With tradition going hand-in-hand with commerce, poultry suppliers don’t really have a reason to try and change domestic consumer appetites for the tails. In preparing his research into the missing treat, Carolan says he had to search high and low before finally finding a source of tails at a Whole Foods that was about to discard them. "[You] can't expect the food to be accepted if people can't even find the piece!"

Unless the meat industry mounts a major campaign to shift American tastes, Thanksgiving will once again be filled with turkeys missing one of their juicier body parts.
