In Defense of Polar Bears

After focusing primarily on grizzlies and black bears in previous posts, I felt it was high time that the polar bears got to have their say in the matter. This is a post that I've been wanting to do for the better part of a year but it's been a long process tracking down all the source material and compiling all of the pertinent information, because - of all the bears - we seem to know the least about the polar bear. One thing that most people do seem to agree on is that the polar bear is the most predatory of the main three in North America, the only one that will frequently regard people as a food source. But is this really true? Despite a few nasty encounters, including some predatory attacks, evidence suggests that this is not the norm.

While bears are primarily classified as omnivores, the polar bear is the only one that is a true carnivore, a necessity due to the lack of vegetation in their icy environment. This is what leads to the common thought that they will usually prey on man, though polar bear attack statistics are extremely low when compared to grizzlies and black bears. While it is true that this is mostly due to the fact that man and polar bear share very little space together, it could also be an indication that the polar bear is not as aggressive as it is often thought to be.

In The World of the Polar Bear, Norwegian Thor Larsen says that he has experienced at least a dozen attacks from polar bears, but that all of them were provoked. Russian researcher Nikita Ovsyanikov, who lived and walked with the polar bears of Wrangel Island and who wrote two invaluable books about the experience - Living With The White Bear and Polar Bears - has had over fifteen hundred encounters with these animals and says that only three of those encounters were with bears that tried to kill him. Even then, he says that he made mistakes that provoked that behavior. In all three incidents, he says that he was able to stop the attacks by carrying a stick, behaving in a confident and aggressive manner, making himself look larger with his parka, and using pepper spray, which has a 100% success rate against polar bears due to the sensitivity of their extremely keen noses (they can often scent seals from up to 25 miles away).

Polar bears can often be the most curious of all bears and have been known to follow people across ice flows, wander into camps, and even poke their heads into tents. With the image of a man-eater in mind, these bears are usually killed right away, without even signs of aggression being apparent. So is the polar bear that peeks inside your tent looking for a meal, or is he simply curious about what's inside? In 1978, Naomi Uemura made the first solo trek into the North Pole and wrote about the experience in National Geographic. He tells the story of a polar bear that entered his camp and approached his tent. Tucked away in his sleeping bag, Uemura was sure he was doomed, particularly when the bear began shredding the tent. However, after one sniff of Uemura in his sleeping bag, the bear turned and padded away.

In October of 2003, the nuclear submarine USS Honolulu surfaced near the North Pole. A lookout onboard spotted three polar bears nearby, who promptly wandered over to the strange thing and began to curiously investigate it, showing no fear, despite having never seen such an object before. In 1990, Nikita Ovsyanikov was reading in his cabin on Wrangel Island one night and suddenly found that the structure was surrounded by polar bears who were peering in the windows and pawing at the walls. Ovsyanikov simply went outside, shooed the bears away, and closed the shutters. Charles Jonkel wrote of tranquilized and captured polar bears, saying that they were as docile as black bears when approached by investigators. Many other researchers who work with the bears on the ice flow have said that they are no more aggressive than the average North American black bear. The gentle side of the polar bear can even be seen in a series of remarkable photographs in which one of the white bears returned to a campsite every night for a week to play, wrestle, and cuddle with a chained-up sled dog (see photos above).

Churchill, Manitoba is considered to be the polar bear capital of the world but there have only been two recorded attacks there since 1717. The locals do face many problem bears, though, but they are easily deterred. More info and even a few amusing stories of face-to-face encounters can be found at the website for Polar Bears International: http://www.polarbearsinternational.org/polar-bears/bear-essentials-polar-style/human-interaction/attacks-and-encounters

Polar bears are also considered to be one of the most intelligent of all bears, as Else Poulsen shows in her wonderful book Smiling Bears. One of her captive polar bears pointedly demonstrated to her why frozen chickens don't make acceptable toys: they thaw out in water. The bear demonstrated this by first catching and holding Else's attention, then using her paw to slosh the bird around in the pool until it thawed, and then slapping it out of the water to show that it would fall apart.

I've shown throughout the course of this blog that there is much we don't understand about bears - all bears - but I think it's very clear that there's even more we don't understand about polar bears. We've come a long way in how we think about black bears, we're still working on changing how we think about grizzlies (though the tide is turning), but we still have a long way to go before we appropriately change our way of thinking about polar bears. That's why it's time to give them the chance to say their piece.

Interesting tidbits: Polar bears are only found near the North Pole, not Antarctica. An easy way to remember this is to keep in mind that the word "arctic" comes from the Greek word for "bear", while the word "antarctic" is from the Greek meaning "without bear".
