Big boys.

Alaskan brown bears are among the largest bears in the world, with adult males weighing in anywhere between 800 to 1,500 pounds and standing at about 8 to 10 feet tall on their hind legs. Females are generally much smaller, weighing only around 400 to 800 pounds.

These bears are omnivorous, so while they primarily feed on plant matter, such as berries, grasses, and roots, they are also opportunistic predators that will hunt.

And these bears here at Katmai National Park love to dig their claws into some fish.

Located at the northern end of the Alaska Peninsula, the park covers an area of approximately 4.1 million acres.  It is particularly renowned for its population of brown bears, which gather along the Brooks River in the summer to catch salmon. Visitors have the opportunity to observe the bears up close in their natural habitat.

Skilled fishermen, they stand in rivers and catch fish by snagging them out of the air with their jaws.

And while an abundance of salmon provides for a relatively safe environment for viewing (bears will full bellies and plenty of fish don’t usually pose a threat to humans), however that’s not to say that it can’t get a little competitive at the fishing hole.

These big males were recently filmed throwing paws at Brooks Falls, and while it was over pretty quick, it sure was intense.

Black Bear Hilariously Breaks Into Truck: “It’s A Freaking Black Bear, Eating Charlie’s Nuts In The Front Seat”

Not the nuts.

These black bears are sneaky and will do just about anything for food.

Break into vehicles, homes, garbage cans and anything else that holds something they think is edible.

They can grow as large as their appetite, weighing up to 600 pounds.

If you ever have the time to watch them, you can’t help but notice how smart they really are. They are very capable animals, able to open things, climb, break and crush their way through the wild.

Black bears love to come into urban areas. More people means they have more access to easy and tasty food sources.

This video from New Hampshire is a perfect example of bears being too smart for their own good. New Hampshire, being relatively small, has a fairly dense black bear population.

The bear is seen sitting in the passenger seat of a work truck just like he’s a person.
