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.
It is considered an abnormal behavior and is sometimes seen in captive animals, particularly those held in small enclosures with little opportunity to engage in more normal behaviors. These behaviors may be maladaptive, involving self-injury or reduced reproductive success, and in laboratory animals can confound behavioral research. [17]
Rather than refer to the behaviour as abnormal, it has been suggested that it be described as "behaviour indicative of an abnormal environment". [6] Stereotyped behaviour can also refer to normal behaviours that show low variation. For example, mammalian chewing cycles or fish capturing prey using suction feeding.
Pollutant-induced abnormal behaviour refers to the abnormal behaviour induced by pollutants. Chemicals released into the natural environment by humans impact the behaviour of a wide variety of animals. The main culprits are endocrine-disrupting chemicals (EDCs), which mimic, block, or interfere with animal hormones.

Abnormality (or dysfunctional behavior or maladaptive behavior or deviant behavior) is a behavioral characteristic assigned to those with conditions that are regarded as dysfunctional. [ 1 ] [ 2 ] Behavior is considered to be abnormal when it is atypical or out of the ordinary, consists of undesirable behavior, and results in impairment in the ...
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.
It is unknown whether animals are able to 'obsess' in the same way as humans, and because the motivation for compulsive acts in non-human animals is unknown, the term "abnormal repetitive behavior" is less misleading. A wide variety of animals exhibit behaviors that can be considered abnormally repetitive.
