Shimmering behaviour of Apis dorsata (giant honeybees). A group of animals fleeing from a predator shows the nature of herd behavior, for example in 1971, in the oft-cited article "Geometry for the Selfish Herd", evolutionary biologist W. D. Hamilton asserted that each individual group member reduces the danger to itself by moving as close as possible to the center of the fleeing group.
Each sheep lifts its head upwards to check the position of other sheep in the flock. This constant monitoring is probably what keeps the sheep in a flock as they move along grazing. Sheep become stressed when isolated; this stress is reduced if they are provided with a mirror, indicating that the sight of other sheep reduces stress. [83]
