Abstract

The activity budget of the impressed tortoise, Manouria impressa (Günther, 1882), was studied at Phu Luang Wildlife Sanctuary, Loei Province, Thailand, from January 2010 - October 2011. A total of fourteen M. impressa individuals, consisting of ten adults (five males and five females) and four juveniles, were radio-tracked. Hiding was the most frequently observed activity in both the wet and dry seasons. The frequency of active behavior in the wet season was higher than in the dry season. Tortoises were found to be active at ambient temperatures ranging from 12.0 ºC - 30.0 ºC, and a relative humidity from 60% - 100%. The year-round averages for air temperature and relative humidity for activity in males, females and juveniles were not significantly different. For all individuals, there was no significant difference in temperature between each active behavior. Two cases of nesting were also observed.
