Some abnormal behaviours may be related to environmental conditions (e.g. captive housing) whereas others may be due to medical conditions. The list does not include behaviours in animals that are genetically modified to express abnormal behaviour (e.g. reeler mice). A polar bear performing stereotyped pacing.
Abnormal behavior of birds in captivity has been found to occur among both domesticated and wild birds. [1] Abnormal behavior 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. [ 2 ]
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]
The main culprits are endocrine-disrupting chemicals (EDCs), which mimic, block, or interfere with animal hormones. A new research field, integrative behavioural ecotoxicology, is emerging. [1] However, chemical pollutants are not the only anthropogenic offenders. Noise and light pollution also induce abnormal behaviour.
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 ...

Vacuum activities (or vacuum behaviours) are innate fixed action patterns (FAPs) of animal behaviour that are performed in the absence of a sign stimulus (releaser [broken anchor]) that normally elicit them. [1] This type of abnormal behaviour shows that a key stimulus is not always needed to produce an activity. [2]
Ethograms are used extensively in the study of welfare science. Ethograms can be used to detect the occurrence or prevalence of abnormal behaviours (e.g. stereotypies, [5] [6] feather pecking, [7] tail-biting [8]), normal behaviours (e.g. comfort behaviours), departures from the ethogram of ancestral species [9] and the behaviour of captive animals upon release into a natural environment.
