How Do You Save Endangered Gorillas? With Lots of Human Help Associated Press KINIGI, RWANDA - Deep in the rainforest of Volcanoes National Park, a 23-year-old female gorilla named Kurudi feeds on a stand of wild celery. She bends the green stalks and, with long careful fingers, peels off the exterior skin to expose the succulent inside. Biologist Jean Paul Hirwa notes her meal on his tablet computer as he peers out from behind a nearby stand of stinging nettles. The large adult male sitting next to her, known as a silverback, looks at him quizzically. Hirwa makes a low hum -- "ahh-mmm" -- imitating the gorillas' usual sound of reassurance. "I'm here," Hirwa is trying to say. "It's OK. No reason to worry." .
