In ethology, an aggregation is any form of gathering of organisms and the process of coming together. In some forms groups of unrelated species might form, in which interaction between members of the aggregation might be minimal; for example herds of grazing zebra and antelopes might combine, both the better to observe the approach of predators, and to improve the odds of escape in the event ...
Such antipredator behavior inevitably results in aggregations. The theory was proposed by W. D. Hamilton in 1971 to explain the gregarious behavior of a variety of animals. [1] It contrasted the popular hypothesis that evolution of such social behavior was based on mutual benefits to the population. [1]
Greater sage-grouse at a lek, with multiple males displaying for the less conspicuous females. A lek is an aggregation of male animals gathered to engage in competitive displays and courtship rituals, known as lekking, to entice visiting females which are surveying prospective partners with which to mate.

Warder Clyde "W.C." Allee (June 5, 1885 – March 18, 1955) was an American ecologist. He is recognized to be one of the great pioneers of American ecology. [3] [4] As an accomplished zoologist and ecologist, Allee was best known and recognized for his research on social behavior, aggregations and distributions of animals in aquatic as well as terrestrial environments.

Behavioral ecology, also spelled behavioural ecology, is the study of the evolutionary basis for animal behavior due to ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined four questions to address when studying animal behaviors: What are the proximate causes, ontogeny, survival value, and phylogeny of a behavior?
Collective animal behavior is the study of how the interactions between individuals of a group give rise to group level patterns and how these patterns have evolved. [5] Examples include the marching of locusts and flocks of migrating birds. Group living however focuses on the long-term social interactions between individuals of a group and how ...
Image: Twitter Even though they may essentially just be giant, glorified guinea pig's, one thing's for sure: Capybaras are the Taylor Swift of the animal kingdom -- they roll deep.
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.
