Abstract


Captive orangutans often showcased distinct behavioral pattern as compared to
wild orangutans. Bukit Merah Orangutan Island, Perak, Malaysia housed and rescued orangutans from Borneo. The activity budgets for the orangutans was dominated by resting (59%). Abnormal behaviour i.e. orangutan using tools was recorded (1.75%) and crucial behaviour in nest building did not occur throughout the study, which led to little time allocated into studying its climbing patterns (1.25%) which is also an associated behaviour in nest building. Apart from nest building, out of 14 other behavioral patterns observed, no aggression behaviour took place. Difference in activity budget and behavioral patterns were found to be significant between gender and age grouping. This study was a part of integrated behavioural and canopy preference survey on captive orangutans in Malaysia.
