Grizzly bear cubs usually stay with their mothers until they emerge from the den in their third spring. By then they should have learned skills essential for survival on their own. This is still, it is a dangerous time for young, inexperienced bears without the protection of their mom and siblings will often stay together for a while, some even denning together the first post-mom winter. Grizzly bears are very playful—cubs treat their moms like a jungle gym. They also play endlessly with each other and even older siblings will still play together as this photo shows. It is common to view bears playing and if the photos were taken out of context one would think they were actually fighting.
