"If they could play cards and swig beer, they probably would. Instead, a gang of gelada bachelors lounge under ancient heath trees, flashing eyelids at a family male (not visible) that provokes them daily with aggressive postures. Like related females, all-male groups will defend and groom each other and huddle for warmth—kind acts between future foes in the battle to reproduce."
—From "Kings of the Hill?," November 2002, National Geographic magazine
