Common marmosets, Callithrix jaccus jaccus, 16 to 23 mounts of age and weighing about 270 g at the outset of the experiment, were placed under light conditions from 0500 to 1900 hr alternating with periods of darkness from 1900 to 0500 hr at a room temperature of 25-27℃, and with food and water available ad libitum. A diurnal rhythm in drinking behavior measured by a specially devised monitor(Saito and Takahashi, 1979) on a 14:10 light-dark cycle per day over a period of 12 days was observed in five pairs of common marmosets. The total number of licks on a water dispenser attached to the water bottle were automatically printed out every hour. The 24-hr drinking patterns of the common marmosets were well synchronized with the light-dark cycle, with 100% of the total daily drinking counts recorded in the light phase. According to gross observation, the daily patterns of eating ran nearly parallel with the drinking behavior. These rests indicate that common marmosets are diurnally active.
