This video was taken on March 17, 2007 at the Henry Doorly Zoo in Omaha, Nebraska. It shows one of the polar bears playing with a ball. She takes a running start (eventually!) and jumps right onto the ball.
So gorgeous! That bear looks so relaxed, enjoying playing with that ball! The bear just waited until it was perfectly aimed correctly to jump right onto the ball! They're really very intelligent. May they multiply and have many cubbies! I hope they let them mate regularly!
