August 7, 2005. Anchorage, Alaska. One very alert grizzly bear. They don't miss much. They used to say that bear had poor eyesight. I never believed it. The now say that a bear can see as well as a human. They do use their nose a lot. They have one of the best noses out there. Often, bears will stand on their hind legs to try to get a visual on something that their other senses aren't telling them about. Just because a bear stands up doesn't mean it is going to attack. Most often when they drop back to all fours, they will turn and run. Awesome to see one standing up close.
