Abstract:

We recorded daily behaviors of mixed captive Manis javanica with two infrared video cameras from March to April, 2013, and analyzed the time budget and activity pattern by using the scan sampling method and focal animal sampling method. The behaviors included feeding (eating, drinking), locomotion (climbing, walking and pacing), social behavior (climbing back, pursuing), hiding (activity unseen), and others (pause, digging, excretion and egestion, bathing). The results showed that the main behaviors of M. javanica were eating (18.56%), walking (16.11%), climbing (11.51%), and social behavior (11.51%). Few digging behaviors (0.92%) appeared at night, and abnormal repetitive behaviors (4.40%) occurred occasionally. Subjects were active intermittently from 19:00 to 06:00. The activity peak occurred between 20:00 and 23:00, which was also the most active period of eating, walking and social behaviors. Eating showed a significant correlation with social behavior in time distribution (R2=0.920, P<0.001) and walking behavior (R2=0.796, P<0.001). We considered that foodproviding time and feeding time might lead to the activity pattern of socially captive M. javanica. In the captive environment, the animals always exhibit stereotyped behaviors but the trend might decrease in the mixed captive environment. Therefore, in order to avoid the decrease of the behavior diversity of M. javanica, we can richen the captive environment, and also provide a mixed captive environment.
