Male and female bears are known as boars and sows, despite being about as closely related to pigs as koalas are to bears, or pandas to raccoons. The bear family’s closest relatives are actually dogs. One thing they do share with pigs is an omnivorous diet – apart from the exclusively carnivorous polar bear – most are as happy snacking on plants and fruit as they are gnawing on the leg of an elk. They can be fussy, too. Only a really hungry brown bear eats a whole salmon. Most of the time it only goes for the high-nutrition bits: the brain, skin and eggs. Polar bears have an odd liking for toothpaste. They have been known to raid Arctic tourist camps, knocking over tents and trampling equipment all in order to suck a tube dry.
Bears spend much of their day eating, laying down fat reserves to get through their seven-month sleep. Technically this isn’t hibernation, but ‘torpor’ because their body temperature, respiration and metabolic rate hardly alter. During this whole time they don’t eat, drink, urinate or defecate but recycle their urea into protein and plug their anuses with a mixture of feces, hair and bedding material called a ‘tappet’. Female bears even give birth in their sleep: the cubs are tiny and premature and weigh a tenth of those of similar sized mammals. As a result bears’ milk is much richer than other carnivores’ and they soon make up for it.
Newborn brown bears hum loudly while nursing, to help stimulate their mother’s milk production. Each cub in a single litter is quite likely to have a different father.
When a pine needle falls in the forest, the eagle sees it; the deer hears it, and the bear smells it.
If a black bear rears up on its hind legs, snarls and roars at you, relax - you're in a film. Black bears don’t roar, and rarely even growl. To get the ‘bear-like’ noise that audiences expect, film producers dub in the sounds of big cats or wolves. Wild black bears also don’t stand on their hind feet when threatened, or bare their teeth - only trained bears will do that. Black bears rarely attack humans, but when they do, there tend to be no dramatic warning signs.
Brown bears (grizzlies) do roar. There is another way to tell the difference between brown and black bears: climb a tree. If the bear climbs up after you, it's a black bear, but if it pulls down the tree and gets you that way, that's a brown bear.
There are about a million black bears in North America, and people continue to believe they are dangerous. However, only three people have been killed by black bears in the eastern USA in the past 100 years. The reason they have big claws and great strength is not for fighting, but so they can rip open logs and turn over stones to eat insect larvae, which make up much of their diet.
Bears like the smell of toothpaste.
'Pig-faced ladies' were created by getting a bear drunk, tying it to a chair, shaving its head, and dressing it up as a woman.

Brown bears can be black and black bears can be brown. Unfortunately, it’s important to know the difference: if confronted by a brown bear, you should play dead. If you do that to a carrion-loving black bear, it will start to eat you. Not that you are in any serious danger.
