An old Indian saying goes something like "when the leaf falls in the forest, the deer hears it, the goat sees it, and the bear smells it".

Wildlife photographer Andy Russel wrote a wonderful account (in his book Grizzly Country) about several days (maybe a week?) he spent photographing an interior grizzly sow and her yearling cubs. He said it took him several days to even begin to suspect she was absolutely blind. She was getting along that well with no vision whatsoever. He did confirm, to his satisfaction, that she was completely blind. He got some fantastic photographs as well.
