Abnormal behaviour in animals can be defined in several ways. Statistically, abnormal is when the occurrence, frequency or intensity of a behaviour varies statistically significantly, either more or less, from the normal value. This means that theoretically, almost any behaviour could become abnormal in an individual.
Extreme displays of stereotypies can be an animal welfare issue as well as a confound in behavioural research. [21] Since much of the behavioural research done on animals requires the subject to have a certain level of normal behavioural functioning, any stereotypic behaviour exhibited by the subjects could compromise the results. [22]
These behaviors sometimes share characteristics with obsessive-compulsive behavior, including a high degree of similarity in form and use among many individuals and a repetitive dimension. There are many observable animal behaviors with characteristic, highly conserved patterns. One example is grooming behavior in rats. This behavior is defined ...

So far, scientists have proved that around 65 species of animals engage in behaviors similar to laughter, and most do so during playful activities. Most of them are primates, but also include ...

When social interactions amongst birds are absent or inadequate, abnormal social behaviour may develop. For example, a study regarding parrots that had been isolated in cages demonstrated that most birds showing this social deprivation had significant behavioural disturbances, such as aggressive behaviour, feather picking, self-mutilation ...
Agonistic behaviour is a result of evolution, [5] and this can be studied in a number of species facing different environmental pressures. Though agonistic behaviours can be directly observed and studied in a laboratory setting, it is also important to understand these behaviours in a natural setting to fully comprehend how they have evolved and therefore differ under different selective ...
