Silverback Mountain Gorilla, Bwindi, UgandaSilverback mountain gorillas are the powerful, mature male leaders of gorilla families, easily recognized by the distinctive patch of silver hair across their backs. They’re responsible for protection, making decisions about movement, and maintaining peace. Despite their massive size and strength, silverbacks are often gentle, especially with infants, and show deep emotional bonds with the entire family. Their expressions can be so very human, like this guy who was relaxing in the forest, but keeping a watchful eye on all the goings on.
