If you’re out hiking and spot an excessively large bird in a tree, take a second look. Black bears don’t need wings to reach the treetops. It’s not uncommon to spot them high up in trees throughout woodlands like the Great Smoky Mountains, where their population is high. And while we think of these bears as ground-dwellers, they seem to be quite comfortable high off the ground. Turns out, there are several reasons black bears spend time at the top of the forest, revealing the skill and agility of these large mammals.

Bears Are Tree Huggers

Black bears routinely climb trees and are comfortable doing so at a young age. You’re more likely to find a black bear climbing a tree than any other bear species. Grizzlies are known for their speed, but black bears can scale trees 100 feet or more in a matter of 30 seconds. Their claws are essential for gripping, helping them to grab branches and thick bark. Powerful legs propel them up tree trunks, and they’re agile enough to balance in high canopies.

When it’s time to come down from a tree, black bears are equally skilled at descending. Unlike humans, who typically climb down feet-first, black bears are daredevils. They can go feet-first or headfirst, depending on the situation. If they need to descend quickly, they’ll likely lead with their heads to get their front paws on the ground quickly.

Why Do Black Bears Climb Trees?

Many black bears spotted in trees are cubs. Mama bears often send their young skittering up trees for protection. A tree serves as a metaphorical bear cub nanny while the mother forages for food and guards the den. In areas where black bears have predators, tree canopies also offer a safe haven. If you come upon a cub in a tree, it’s important to note that mama bear is undoubtedly nearby.

Safety isn’t the only reason black bears climb trees. They survive on a diet primarily consisting of nuts, leaves, and berries. Good tree-climbing skills mean a higher yield of both. Adult black bears may climb trees if food is scarce or if they catch a whiff of fruit. In some cases, a bear may climb a tree in search of bird eggs. After a nice meal, trees also become places to rest. A satiated black bear may find a sturdy branch to be the perfect napping spot, knowing it’s safe off the ground.
