Brooks camp area in Alaska is home to at least 100 bears. In 2012 the National Park Service posted cameras throughout Brooks Camp so that others could watch the brown bears as they fish for their food.

The camera feed from the falls is one of the most exciting to watch as the larger males compete for fish.

Brown bears can become aggressive, especially when it comes to food, but mother bears can be even more vicious in defense of their offspring. The term "protective as a mother bear" becomes very obvious when witnessing a mother bear protecting her babies.

Brown bear cubs are born during the winter months and leave the den around June. However they continue to be under the constant supervision of their mother until they mature. Once a brown bear gives birth to a litter she watches over her offspring for the next two to four years. During this time she tends not to mate until her cubs are fully grown.

In the clip below from the live bear cam which is streamed from Alaska's Katmai National Park and Preserve, a mother bear brings her babies to the waterfall to watch as she fishes.

But as inquisitive babies go, they try to follow her and get swept over the waterfall. Mama bear quickly swings into action with much ferocity to protect her cubs from a charging brown bear at the bottom of the waterfall. Enjoy the clip and watch nature at it's best.
