Indian Muntjac, Muntiacus muntjak (Zimmerman 1780) is a species under cervidae family, naturally found in the forested regions of south and south-east Asia. To understand their activities, a study was made on the adult male and female Muntiacus muntjak in the captivity of Jawaharlal Nehru Biological Park, Bokaro, Jharkhand in different season using Scan Sampling Method.

It was observed that barking deer spent nearly 70 percent of time in activity while rest of time they were in resting during the diurnal hours. Among the daily activities, 20% of time spent in feeding, followed by 19 % of time in walking, and approximately 12% time in scanning and social activities. Further, the comparative study of the male and female individuals, it was found that male spent more time in feeding, movement and other activities compared to the female while, female spent more time in scanning and resting activities compared to male.
