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.
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.
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]
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 ...

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 ]
Stereotypical behaviors in animals are generally thought to be caused by artificial environments that do not allow animals to satisfy their normal behavioral needs. Rather than refer to these behaviors as abnormal , it has been suggested that they be described as "behavior indicative of an abnormal environment".
The ethological concept of species-typical behavior is based on the premise that certain behavioral similarities are shared by almost all members of a species. [1] Some of these behaviors are unique to certain species, but to be 'species-typical' they do not have to be unique, they simply have to be characteristic of that species.
