Collective animal behaviour
coordinated behavior of large groups of similar animals / From Wikipedia, the free encyclopedia
Collective animal behaviour describes and analyzes the behaviour of groups of animals. In these groups, the animals are often all of the same species. As an example, a school of fish will be made of mostly the same type of fish and a flock of birds will have the same type of bird. A herd is a large group of hoofed, herbivorous mammals.
Animals tend to behave in such a way because this behaviour offers them a benefit. The group of animals also behaves differently from a single animal. Collective animal behaviour is about finding the rules each animal follows; how it communicates with other members of the group and how a decision to do something is reached in the group.
