This is a photo of a large male gorilla sunning himself on a rock at the pittsburgh zoo.
Mother chimpanzee rests by the water while her baby (apparently a bit of a "toddler") tests its abilities and independence next to her by climbing a tree. Reaches for a branch that is just slightly too far away. Father is in background, guarding the mother and child. Usable as a wildlife photo or with a piece on families or parenting.
