For captive gorillas, trees should be available to climb and material such as straw, branches, or bamboo supplied for nest building.
I have made my home among the mountain gorillas.
Play seems to be one of the first activities inhibited by the presence of an observer until a group becomes well habituated. For this reason, I consider it more common than previously thought.
Gorillas are the largest of the great apes. A mature male may be six feet tall and weigh 400 pounds or more; his enormous arms can span eight feet.
Those bearing the heavy responsibility of caring for captive gorillas should be encouraged to exchange so-called nonbreeders between populations, an inherent process among free-living gorillas and one that avoids inbreeding and also stimulates productivity.
