Can Brown Bears Survive in the Pyrenees?

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.
On the evening of August 4, 2019, two hikers set up camp in the Pyrenees Mountains. Laurent and Frédéric were familiar with the area and had plenty of experience hiking and camping. Once their camp was ready for the night, they took off their boots and socks and sat down to eat dinner and relax at a small campfire. If you’ve ever camped after a long hike, you’ll know that this is the best time of the day, when you can rest and air out your boots.
After only a few minutes, though, the two heard grunts and growls in the darkness not far from their camp. They were concerned, but they had a fire and most animals won’t approach a fire. But the sounds got closer and closer.
Then the animal roared—and it sounded like it was much closer than before. Laurent and Frédéric remembered that bears have become more common in the Pyrenees in the last few decades, and rather than take their chances with a hungry bear, they decided it was time to go. They shoved their bare feet into their boots, left everything behind, and raced back down the trail.
It was late when they made it to the village of Germ so the hikers took refuge in a church where they spent the night. In the morning they hiked back up to their campsite to retrieve their belongings, expecting it to be trashed by a bear hunting for food. But everything was where they’d left it.
Some people assumed the hikers had panicked over nothing, but the men were adamant that they’d heard something roaring as it came closer. In a news interview they said the final roar, the one that made them grab their boots and run, lasted several seconds and was so loud they could actually feel it in their chests.
Brown bears were once fairly common in the Pyrenees but by 1991 they had all been killed, mostly by hunters. Habitat loss was also a factor as people built more roads and houses in the mountains. In 1995 a conservation program brought three bears from Slovenia to start a reintroduction program, and the way people acted, you’d think someone had released a thousand rabid weasels into their homes.
Sheep and cattle farmers, and people who think the wilderness belongs to humans and humans only, protested the reintroduction of the bears, and one of the bears was shot and killed. This is despite the fact that farmers whose livestock are killed by bears get paid a lot of money by the French government. Approximately 1,000 sheep a year are killed in the Pyrenees—not by bears, but by pet dogs running loose.
Conservation efforts continued despite protests and finally, by 2020, there were 64 bears living in the Pyrenees Mountains. The number may be a little larger—some estimates are as high as 100—but conservationists have difficulty counting the bears properly because protesters threaten them and in one case actually set a conservationist’s car on fire.
The Pyrenees mountain range more or less divides France from Spain. It’s older than the Alps and especially known for its spectacular waterfalls. Many plants and animals that live in the Pyrenees are found nowhere else in the world, but unfortunately hunting and habitat loss have driven many of them to extinction. The Pyrenean ibex, a type of wild goat, went extinct in the year 2000.
Conservationists have introduced a related animal, the western Spanish ibex, to help keep the mountain ecosystems healthy. The bears now living in the mountains are similarly important to the ecosystems. Conservationists are frustrated by protesters who don’t want bears in the mountains at all, especially considering that the Great Pyrenees dog was developed in the area to protect livestock from bears and other predators. Some shepherds in British Columbia, Canada, where both black bears and grizzlies live, successfully use Great Pyrenees dogs to guard their flocks from bears. Grizzlies are a subspecies of brown bear.
But let’s go back to Laurent and Frédéric’s scary camping trip. Did they really encounter a bear or could it be something else?
Bears are generally quite shy animals who avoid people when they can. Unlike black bears, which don’t growl, brown bears do make growling and grunting sounds occasionally. Males will growl or even roar at other males during mating season in spring and early summer, signaling aggression and the willingness to fight. A brown bear will sometimes growl or roar at a person to warn them away too. So it’s possible the hikers heard a bear who wasn’t interested in their food but just wanted them out of its territory.
There’s another possibility, though, and it’s an animal that’s much more common in the Pyrenees Mountains than bears are. The wild boar lives throughout the Pyrenees, especially in forested areas and meadows. It’s mostly nocturnal and is usually shy of humans, and its numbers have increased considerably since its main predator, the wolf, was driven to extinction in the mountains and elsewhere in the 1930s.
An estimated two million wild boars live in France, including the Pyrenees. The most common time for people to encounter wild boars is at dusk, which is exactly when the hikers heard the growling. But wild boars are just pigs, right? Pigs oink, right?
This is what an aggressive wild boar sounds like:
[boar growl]
A boar will growl to warn other boars that there’s danger nearby and to signal aggression. That would explain why the hikers heard grunts and growls, which finished in a loud, angry roar. It would also explain why the campsite was undisturbed. Wild boars mostly eat plants, including roots, nuts, and fruit, although they’ll also eat carrion and the occasional small animal if they can catch it. Unlike a bear, which almost always wants to eat people food when it can, a wild boar is a lot less interested in people food. If the hikers did hear a boar instead of a bear, once they ran away the boar was probably satisfied and just went around finding its natural food in the area as usual.
Wild boars have been introduced to parts of North and South America, Australia, and other places where they’ve become an invasive species. The wild boar is native to Europe and Asia, though, so the ones in the Pyrenees are right where they belong. The only real issue is the lack of natural predators to keep the boar population at a healthy level.
The good news is that wild boars aren’t usually as aggressive as they can sound, as long as they’re not cornered. The two hikers were probably not in any danger after all. Still, it’s better to be safe than sorry when you get roared at by a large creature in the dark.
