A herd is a social group of certain animals of the same species.
Herd may also refer to:

In the social sciences, a social group is defined as two or more people who interact with one another, share similar characteristics, and collectively have a sense of unity. Regardless, social groups come in a myriad of sizes and varieties. For example, a society can be viewed as a large social group. The system of behaviors and psychological processes occurring within a social group or between social groups is known as group dynamics.
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.
Panic is a sudden sensation of fear, which is so strong as to dominate or prevent reason and logical thinking, replacing it with overwhelming feelings of anxiety, uncertainty and frantic agitation consistent with a fight-or-flight reaction. Panic may occur singularly in individuals or manifest suddenly in large groups as mass panic.
Boids is an artificial life program, developed by Craig Reynolds in 1986, which simulates the flocking behaviour of birds, and related group motion. His paper on this topic was published in 1987 in the proceedings of the ACM SIGGRAPH conference. The name "boid" corresponds to a shortened version of "bird-oid object", which refers to a bird-like object. Reynolds' boid model is one example of a larger general concept, for which many other variations have been developed since. The closely related work of Ichiro Aoki is noteworthy because it was published in 1982 — five years before Reynolds' boids paper.
Herding is the act of bringing individual animals together into a group (herd), maintaining the group, and moving the group from place to place—or any combination of those. Herding can refer either to the process of animals forming herds in the wild, or to human intervention forming herds for some purpose. While the layperson uses the term "herding" to describe this human intervention, most individuals involved in the process term it mustering, "working stock", or droving.
Cooperation takes place when a group of organisms works or acts together for a collective benefit to the group as opposed to working in competition for selfish individual benefit. In biology, many animal and plant species cooperate both with other members of their own species and with members of other species with whom they have relationships.
A herd is a social group of certain animals of the same species, either wild or domestic. The form of collective animal behavior associated with this is called herding. These animals are known as gregarious animals.
Flock, flocks or flocking may refer to:
Herd mentality is the tendency for people’s behavior or beliefs to conform to those of the group they belong to. The concept of herd mentality has been studied and analyzed from different perspectives, including biology, psychology and sociology. This psychological phenomenon can have profound impacts on human behavior.
A stallion is a male horse that has not been gelded (castrated). Stallions follow the conformation and phenotype of their breed, but within that standard, the presence of hormones such as testosterone may give stallions a thicker, "cresty" neck, as well as a somewhat more muscular physique as compared to female horses, known as mares, and castrated males, called geldings.
Collective effervescence (CE) is a sociological concept coined by Émile Durkheim. According to Durkheim, a community or society may at times come together and simultaneously communicate the same thought and participate in the same action. Such an event then causes collective effervescence which excites individuals and serves to unify the group.
Horse behavior is best understood from the view that horses are prey animals with a well-developed fight-or-flight response. Their first reaction to a threat is often to flee, although sometimes they stand their ground and defend themselves or their offspring in cases where flight is untenable, such as when a foal would be threatened.
Collective mental state is generally a literary or legal term, mostly used in sociology and philosophy, to refer to the condition of someone's being-state when around others. An assessment of a collective mental state includes a description of thought processes, memory, emotions, mood, cognitive state, and energy levels, including the meta overlay of interactions between individuals.
Test(s), testing, or TEST may refer to:
Herd behavior is the behavior of individuals in a group acting collectively without centralized direction. Herd behavior occurs in animals in herds, packs, bird flocks, fish schools and so on, as well as in humans. Voting, demonstrations, riots, general strikes, sporting events, religious gatherings, everyday decision-making, judgement and opinion-forming, are all forms of human-based herd behavior.
Collective animal behaviour is a form of social behavior involving the coordinated behavior of large groups of similar animals as well as emergent properties of these groups. This can include the costs and benefits of group membership, the transfer of information, decision-making process, locomotion and synchronization of the group. Studying the principles of collective animal behavior has relevance to human engineering problems through the philosophy of biomimetics. For instance, determining the rules by which an individual animal navigates relative to its neighbors in a group can lead to advances in the deployment and control of groups of swimming or flying micro-robots such as UAVs.
A group is a number of persons or things that are located, gathered, or classed together.
Allelomimetic behavior, or allomimetic behavior, is a range of activities in which the performance of a behavior increases the probability of that behavior being performed by other nearby animals. Allelomimetic behavior is sometimes called contagious behavior and has strong components of social facilitation, imitation, and group coordination. It is usually considered to occur between members of the same species. An alternate definition is that allelomimetic behavior is a more intense or more frequent response or the initiation of an already known response, when others around the individual are engaged in the same behavior. It is often referred to as synchronous behavior, mimetic behavior, imitative behavior, and social facilitation.
The selfish herd theory states that individuals within a population attempt to reduce their predation risk by putting other conspecifics between themselves and predators. A key element in the theory is the domain of danger, the area of ground in which every point is nearer to a particular individual than to any other individual. 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. It contrasted the popular hypothesis that evolution of such social behavior was based on mutual benefits to the population.
