Bear Cub Fight

Captured at USA's Big Bend National Park in Texas, the video shows the bear siblings pushing, pulling and chasing each other as an adult - possibly their mom or dad - keeps a watchful eye.

Lindsay Mattick's great-grandfather was on his way to fight in World War I when he bought a bear cub he named Winnie, inspiring author AA Milne to create the timeless character Winnie-the-Pooh. Now, Mattick has written a new children's book chronicling the real-life story behind the bear.
