Silverbacked Gorillas Engaged in Sparring Match
The video was shot at Omaha's Henry Doorly Zoo & Aquarium back in October.
The action starts around the :32 mark, when one gorilla crosses in front of the other,
leading that one to charge and collide into him. The two shove and swipe at each other for
about 15 seconds before one of the apes backs off.
