A similar and simultaneous behavior in a numerous group of individuals of a same species.
Collective behavior can be observed in all societies, from amoebas to human groups. Coordination of moves or other activities results from some specific factor as for example pheromones, or reciprocal visual perception (in fish shoals, for example), or gestual or spoken language.
Normally collective behavior is reinforced by repetitive action that works as a positive feedback. This can even lead to exponential or massive effects (swarming, communal building, in insects… and people, panics, etc)
Curiously, in some cases some unfavorable factor, a negative feedback can lead to the reduction, or even the suppression of some behavior. C. Defrain and J.K. Deneubourg give the example of ants trails abandonned when a source of food is nearly exhausted or if some obstacle or danger intervenes. (2000, p. 147)
