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.
Stereotypies are repetitive, sometimes abnormal behaviors like pacing on the perch for birds. There are adaptive stereotypic behaviors such as grooming in cats and preening in birds. Captive parrots commonly perform a range of stereotypies. These behaviors are repeated identically and lack any function or goal.

When supply is truly scarce, Adélie penguins are known to engage in a form of prostitution. This behavior was first observed in 1998 by researchers from the University of Cambridge and 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.
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 ]

To date, this has been the only study of the Cape Adare rookery, the largest Adélie penguin colony in the world, and he has been the only one to spend an entire breeding cycle there. [3] His observations of the courting, mating, and chick-rearing behaviours of these birds are recorded in his book Antarctic Penguins. [4]
