This study was undertaken to create an Asiatic black bear (Ursus thibetanus; ABB) ethogram during hibernation and to describe the time budget of hibernating behaviours in ABB. Seven captive adult ABB were included in the study and began hibernation between October and December. Data were collected for three consecutive years (2013–2015) during ABB hibernation (total 169 days) using closed-circuit television. During the study, we observed 21 distinct behaviours in hibernating ABB (4 least active and 17 active behaviours). Five bears started hibernation less than seven days after feeding cessation, and by the end of one week, all bears hibernated. The most commonly observed behaviour was “sleep curling inside nest”, and “nest maintenance” was the second most common behaviour. Among the active behaviours, “sitting in the nest”, “change stance”, “drinking and eating” were mostly shown as documented during the observation times. Our results provide new insights into the hibernating behaviours of ABB.
