Black Bear Cubs Fall Off Hammock (VIDEO)

These two black bear cubs may have just found the best place to hibernate. Unfortunately, they haven't quite gotten the hang of a hammock yet.

As an observer in the video comments, "they have the art of getting on that hammock mastered. Staying on is a different story."

Either way, these two cubs seem determined to lounge together on the hammock. Sibling rivalry wasn't a factor like it was for the two bear cubs in Yosemite who mistook a road for their wrestling ring.

Not all bears are so cute and cuddly.

There have been recent attacks on humans in Yellowstone National Park, central Pennsylvania, and near Montana, among other places.

In many cases, the bears were thought to have been defending their cubs, and wildlife groups remind us that intruding into bear habitats can be dangerous.
