Watching some YouTube videos recently on bears, I found that some people left comments asking if bears could climb trees. I wanted to clarify this, so in this article, we look at whether all bears climb trees and if they are good climbers.
Bears can climb trees, with some species being better than others. The American black bear is especially fast at climbing. Grizzly bear cubs can also climb, but most adult brown bears do not due to their size and weight.
Here we look at answering some questions you may have about the climbing abilities of bears.
Why Do Bears Climb Trees?
Bears climb trees to help them stay safe and away from predators and rest, eat and play. Bears will climb trees to get food. American black bears will climb trees for fruit, bird eggs, cactus fruit, honey, acorns, and berries.
Some young brown bears will climb a tree to chase prey, such as a human trying to escape. If they can smell food, most likely human-made, then adult grizzly bears may also try to climb the tree to reach it.
American black bears will also climb trees to escape from predators and reach safety. Cubs of black bears can be made by the mother to climb the tree, to keep them out of reach of predators.
How Do Bears Climb Trees?
Black bears are excellent at climbing and use all four legs. They push their bodies up with their hind legs while pulling and gripping using their front legs. Some do this quickly, making it look like they are walking up the tree. The claws of the American black bear are hooked, which helps them grip the tree.
Brown bears are usually too heavy to pull themselves up using their front and hind legs, using branches to help them. They use the branches as a ladder, with the branches being used as steps to climb up the tree. Brown bears can climb trees with low branches.
How Do Bears Climb Down Trees?
Bears climb down the same way they go up the tree, with their heads at the top. Bears have been seen to climb down trees in a walking fashion but have also been seen to slide down or jump down from lower elevations.
Some mammals, such as squirrels, are adept at climbing and coming down trees. Squirrels can come down headfirst, with their bodies and tail behind them. Bears, although they are good climbers, can not do this.
Black bears are excellent climbers. They can climb at incredible speeds, and you would not be able to get away from a black bear by climbing a tree. Just watch the video below for an example.
Large adult bears of some species also lose their ability to climb trees as they get older. Brown bears can climb trees when they are cubs, but their size and weight increase as they get older. Adult brown bears cannot climb trees with the added bulk, although they can when young.
Brown bears are also not good at climbing trees due to other physical drawbacks. Apart from their size and weight, brown bears have claws that make them harder to climb. Their claws are long and sharp, which makes it difficult for them. Brown bears also have fixed wrist joints and paws that turn inwards. Their paws have naked skin that is rough to the touch; however, this could get easily damaged. Grizzly bear cubs are excellent climbers, and some adults have been seen at heights of up to 18 feet.
There are many species of bears, and all can climb trees, except for one. The polar bear, which can be found in the Arctic, does not climb trees. This is mainly due to their enormous size and weight. There are also hardly any trees in their frozen habitat to climb, even if they could.
Although polar bears cannot climb trees, they are excellent at climbing the terrain in their environment. Polar bears can use their claws and immense power to traverse terrain up to 30-35 feet high and jump down gaps of 10 feet without injuring themself.
There are eight bear species globally, but only three can be found in North America. The three North American species are the American black bear, the brown (grizzly) bear, and the polar bear. As discussed earlier, polar bears do not climb trees due to their size, weight, claws, and lack of trees. However, American black bears are better climbers than brown bears.
The other bears worldwide are the Andean bear, Asiatic black bear, giant panda, sloth bear, and the sun bear.
The Andean bear, found in South America, is a great climber. The Andean bear spends more time in the trees than any other bear species. This species of bear can not only climb large, thick trees but is also able to climb up smaller diameter trees, branches, and even vines.
Asiatic Black Bear
The Asiatic black bear can also climb trees with the same purpose of feeding and safety as other bears. However, the Asiatic black bear is unique among bears in that they also hibernate in trees. As with brown grizzly bears, Asiatic black bears can get too heavy in later life to climb.
The giant panda is a black and white bear found in China. The giant panda is not a good tree climber and has often been described as clumsy when climbing.
Unlike other bears, giant pandas climb trees using their hind legs to push up, then using their front legs, appearing almost caterpillar-like. Giant pandas climb trees as defense, not to find food.
The sloth bear can be found in India and Sri Lanka. The sloth bear hangs upside down when in trees, similar to sloths found in Central and South America.
Sloth bears are among the best climbers out of all the bear species. They can climb trees with rough bark, as other species do, and completely smooth poles.
Sloth bears are also unique because they climb trees, jumping short distances up the tree before hooking their claws in.
The sun bear is the undisputed king of climbing bears. Sun bears are agile and quick, climbing for food, but also to rest. Soon after the cubs are born, they are better at climbing than running on the ground for the first few months.
The sun bear has large claws, which, once in the trees, they hook into the branches, hanging there with their bodies away from the trees.
