At this time, the activity reaches its maximum values: 81% in the spring (from 21 to 22 h); 85% in the summer (from 22 to 23 h) and 78% in the summer (from21 to 22 h).Musk deer are less active between 9 and 19 h. During particular time intervals (from 9 to 11 in the spring and from 9 to 10 h in the fall), musk deer were active less than 30% of the time (Fig. 2). In general, the nature of the daily activity rhythm of musk deer in different seasons is very similar.
