    This cub swap might be more common than we think. What is really surprising about this is that it underlines one more time how little we know about bears. I have seen a small apparently orphan black bear cub approach one of the dominant male black bears in the habitat. . while we watched we thought for sure the little cub would be killed and or eaten as that is what we have been told and taught by biologists. Instead the two bears rubbed noses and continued to eat side by side and eventually drifted off together. I also think that we have been led to believe that bears are solitary animals and that too is not necessarily true. A bears idea of hanging out with other bears may mean there is a mile or two between them. I hope we hear more about this cub swap.
