Activity budgets were studied in eight Asian elephants (Elephas maximus) at Chester Zoo (UK) for 35 days, between January and November 1999. Recordings were made between 10:00 and 16:00 hr (with most behavior frequencies calculated between 10:00 and 14:00hr). The elephants exhibited variation in activity depending oil their age, sex, the time of day and the time of year. Only the five adult cows exhibited stereotypic behavior, With frequencies ranging from 3.9 to 29.4%, of all observations. These elephants exhibited individual, diurnal and seasonal variation ill stereotypic behavior. This has implications for studies that use short sampling periods and may make comparisons of data collected at different times of the day or year invalid. The six adult elephants Spent 27.4-41.4% of the time feeding (between 10:00 and 14:00hr), 22.9-42.0% standing still, 6.1-19.2% walking and 3.9-9.6% dusting. The hypothesis that the frequency of stereotypic behavior in adult cow elephants was negatively cot-related with the frequency of feeding behavior was tested and was found to be true. Stereotypic behavior increased ill frequency toward the end of the clay-while waiting to return to the elephant house for food-and elephants spent more time stereotyping during the winter months than during the summer months. Elephants were inactive (i.e. exhibited behaviors other than locomotion) for between 70.1 and 93.9% of the time. Creating more Opportunities for elephants to exhibit foraging behavior and the introduction of greater unpredictability into management regimes, especially feeding times, may reduce the frequency of stereotypic behavior and increase general activity levels.
