gorilladoctors's video: Silverback Mountain Gorillas Face Off in Rwanda

Dr. Dawn Zimmerman of Gorilla Doctors films an interaction between the Urugamba Kuryama mountain gorilla groups in Rwanda's Volcanoes National Park. At first, we see silverback Urugamba on high alert while his family members rest nearby. Then Kuryama group comes into view. Both silverbacks want to keep their families safe and prevent the other silverbacks from stealing their females. The two silverbacks display—strutting with their lips pursed to look fierce and breaking branches—but never come to blows. Gorilla Doctors' international team of veterinarians is the only group providing wild mountain gorillas with direct, hands-on care in the wild. www.gorilladoctors.org
