Tóm tắt

The activity budget of ring-tailed lemur (Lemur catta) during the wet spring in Northern Vietnam was studied based on 4 lemur individuals at Hanoi Zoo from March to April 2021 with a total of 23 observation days. Generically, the lemurs spent most time resting (48%), moving (19%), feeding (16%), less for vigilance (8%), intra-specific interactions (5%), grooming (2%), and playing (2%). No weird behavior has been found. There was no statistically significant difference between the proportion of time spent on the behaviors of this study and the results of Caselli et al. (2022) through the Chi-squared test (X-squared = 30, df = 25, p-value = 0.2243). However, it seems that the animals need more space to move and avoid conflict between individuals because the time spent on resting, vigilance, and intra-specific interactions was slightly high.
