Swarm behaviour, or swarming, is a collective behaviour exhibited by entities, particularly animals, of similar size which aggregate together, perhaps milling about the same spot or perhaps moving en masse or migrating in some direction. It is a highly interdisciplinary topic.
The transformation of the locust to the swarming form is induced by several contacts per minute over a four-hour period. [11] A large swarm can consist of billions of locusts spread out over an area of thousands of square kilometres, with a population of up to 80 million per square kilometre (200 million per square mile).

The common starling (Sturnus vulgaris) has iridescent plumage.. Starlings are medium-sized passerines. [3] The shortest-bodied species is Kenrick's starling (Poeoptera kenricki), at 15 cm (6 in), but the lightest-weight species is Abbott's starling (Poeoptera femoralis), which is 34 g (1 + 1 ⁄ 4 oz).
SPP models predict that swarming animals share certain properties at the group level, regardless of the type of animals in the swarm. [11] Swarming systems give rise to emergent behaviours which occur at many different scales, some of which are turning out to be both universal and robust. It has become a challenge in theoretical physics to find ...
Swarming is a honey bee colony's natural means of reproduction.In the process of swarming, a single colony splits into two or more distinct colonies. [1]Swarming is mainly a spring phenomenon, usually within a two- or three-week period depending on the locale, but occasional swarms can happen throughout the producing season.
Since fields of many fish will overlap, schooling should obscure this gradient, perhaps mimicking pressure waves of a larger animal, and more likely confuse the lateral line perception. [34] The LLO is essential in the final stages of a predator attack. [37] Electro-receptive animals may localize a field source by using spatial non-uniformities.

Most krill are swarming animals; the sizes and densities of such swarms vary by species and region. For Euphausia superba , swarms reach 10,000 to 60,000 individuals per cubic metre. [ 63 ] [ 64 ] Swarming is a defensive mechanism, confusing smaller predators that would like to pick out individuals.
