The behaviours of ten critically endangered Javan rhinoceros (Rhinoceros sondaicus) were observed using video camera traps on the peninsula of Ujung Kulon National Park (06o 38’30’–06o 52’30’ south and 105o 12’00’–105o 37’30’ east), and were organized as descriptive lists of activities (ethogram). Behavioural data were analyzed by examining the length of time each individual rhino displayed a specific activity (duration). Duration of each activity was calculated as a proportion within a total observation time (length of rhino observation in video recording). In addition to duration, the frequency of each activity was recorded. A quantitative analysis summarizing duration and frequency of activities will be used as baseline information about Javan rhino behaviours that can enrich our knowledge of this reclusive species. The results from this study suggest that the use of video trap equipment for quantifying the behaviour of Javan rhinoceros is promising.
