Stereotypic behavior of a female Asiatic elephant (Elephas maximus) in a zoo.

This study recorded daytime behavior of a female Asiatic elephant at the Municipal Zoo, Wroclaw, Poland, in both an indoor pen and an outdoor paddock as continuous scan sampling for 140 hr, over 35 days in 1 year. Stereotypic sequences involved bouts of highly repetitive stereotypic movements and much more variable interbout behavior. The study found both stereotypic movements, nodding and body (corpus) swaying, were asymmetric, accompanied by protraction of the right hind leg and to-and-fro swinging of the trunk. The elephant spent 52% of the daytime in stereotypic movements, 3.5 times the level reported for females in other zoos' groups. The share of time devoted to stereotypic behavior was lowest in the summer when the elephant was regularly released to the paddock and highest in the late fall after she had stayed in the pen after months of days outside. This suggests that changes in the management routine enhance stereotypies. Comparing the summer and winter stable management periods, stereotypies were much more frequent in the indoor pen than the outdoor paddock, suggesting that the confinement to a barren pen contributed to the observed levels of stereotypies.
