Stereotypic behaviour: repetitive and fixed behaviour without any apparent goal or function. Stereotypic behaviour is  induced by frustration, repeated attempts to cope, and/or central nervous system dysfunction. Stereotypic behaviour occurs when there is a significant discrepancy between the conditions offered by captivity and an animal’s preferred and/or natural state (from Mason, 2006).
