Sorry, Preteens, Horses Are Mean Girls Too
LatestIf you spent some part of your childhood wishing you could run with wild horses, you’re not alone. But you might have been alone once you joined the herd. Horses, it turns out, are just as cliquey as fifth-grade girls.
Horses are all over YA literature, using their soulful eyes to connect deeply with kids and other humans. They gallop through the Saddle Club series, War Horse, and My Friend Flicka—all the way back to Black Beauty, which got a jump on the genre in 1877. Some of the protagonists of horse books are boys, but girls are always the famous horse lovers, whether they prefer the fictional or ride-able kind.
Why girls are so enamored of large, indentured grazers is an open question. But even scientists aren’t immune. “As a child I used to love horses,” says Léa Briard, a graduate student at the Institut Pluridisciplinaire Hubert Curien in Strasbourg, France. “They were my favorite animal.”
But, she claims, that’s not why she’s studying them for her PhD research. Horses are social animals that can teach scientists a lot about group behavior, Briard says. They’re domesticated, but they can also live on their own. (Sure, 10-year-old girl, just like you.)
There are the mustangs of the American West, for example, and horses in Australia called brumbies. And, as anyone who’s read Misty of Chincoteague knows, herds of Chincoteague ponies live on an island off the Maryland coast. (None of these are really wild horses so much as feral horses. They’re descended from domesticated animals, like roaming bands of cats. True wild horses—animals never domesticated by humans—are extinct except for the endangered Przewalski’s horse, which looks like a chubby donkey and lives in Mongolia.)
Despite all these horsey societies running around, scientists have mostly studied the animals as they relate to humans. Briard is more interested in how horses make group decisions. “Are you equally influenced by all the members of your group, or do your friends have more impact on your decision?” she says.
So, to figure it out, Briard and her colleagues have been spying on horses. For a recent study, they spent 200 hours observing three dozen mares living on a hilly pasture in eastern France. They recorded all the horses’ friendly interactions (standing next to each other), unfriendly interactions (biting, kicking), and movements (“Let’s be under that tree now”).
The scientists also assessed each horse’s personality. “Soulful gaze” wasn’t one of the traits they studied. But they did measure gregariousness: how much time did the horse spend standing near others? They also looked at fearfulness: how often did the horse shy or get startled?
They saw that the friendliest horses were also the most fearful. It sounds counterintuitive, but Briard says you can see the same effect in sheep, fish, and birds. “The more fearful you are, the more time you spend close to other individuals,” she says. In other words, horses that hang out by themselves are braver. If your inner preteen loner wants to feel smug about this, let her.
