Casey Anderson of Bozemen, Mont., tickles the feet of Bella, a rescued grizzly cub from Alaska. According to the YouTube video posted May 20, 2016, Andersen cares for Bella and plays something called "space" which teaches Bella to respect him and his space. Andersen can move into Bella's space, and she will actually yield that space to him. That's unusual for a grizzly who will soon outweigh humans.

Andersen has Bella at Montana Grizzly Encounter, his grizzly sanctuary where he rescues grizzly bears. According to his website, he founded the sanctuary to rescue grizzlies and to educate the public about the bears in an attempt to save both human and bear lives. Andersen has been able to build a truly unique relationship with both Bella and Brutus, two rescued grizzlies.

Is the interaction depicted in video below typical of grizzly bears? Are grizzly bears safe?

Most grizzly bears live in the wild and do not get the chance to interact with humans the way Bella does in the video with Andersen. Western Wildlife points out that if you see a grizzly, you should give the bear his space and not make him feel threatened. As long as the bear has an escape route, he shouldn't bother you, and you should be fine viewing him at a distance. According to Wikipedia, only four grizzlies have been trained to be in films since 1966.

Generally speaking, Western Wildlife states that as long as a grizzly bear doesn't feel threatened and has an escape route, he won't bother humans. Leaving a mama and her cub alone is always wise, and not getting between a bear and the food he wants is prudent. If you keep these things in mind, the grizzly bear is generally a safe bear.

What are 3 surprising facts about grizzly bears?

Interesting Fun Facts shares a number of cool facts about grizzly bears. The first surprising fact is that grizzlies can run up to 30 mph (48 kph). Since grizzlies can weigh anywhere from 352 pounds (160 kg) to 661 pounds (300 kg), the average bear can eat up to 88 pounds (40 kg) of food a day. Lastly, when the bear goes to hibernate, his heart rate drops from 40 beats per minute to 8 beats per minute. 

In so many different ways, the grizzly bear is truly amazing. The bear is extremely fast, yet surprisingly gentle with man. He eats a ton of food to build up for the winter, and then slows his heart rate and metabolism down so that he can last for months without food or water. The bear is a truly extraordinary animal.
