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 ]
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 ...
The study, which was published in the Journal of Animal Ecology, determined that long-term exposure to this drug, even at lower concentrations, affects fish both as individuals and as larger ...

For example, painted goby males did not take part in visual courtship behaviour when in a noisy environment. [15] Female painted gobies in this experiment were also less likely to spawn in a noisy environment. Noise pollution can also affect foraging behaviour in marine animals, which results in less effective strategies.
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".
