Behavior of female at the primate research center breeding facility.

BACKGROUND

Behavioral studies are crucial for conservation because animals must exhibit natural behavior as a principle of animal welfare. To achieve this, the behaviors of animals in captivity must be compared with those of animals residing in their natural habitats to ensure that they live naturally.

AIM

This study aimed to describe the behaviors of female in captivity to facilitate comparisons with wild individuals.

METHODS

The subjects of this study were three adult T. spectrumgurskyae females observed for 15 months in a captive breeding facility at the Primate Research Center of IPB University, Bogor.

RESULTS

Female spend most of their time moving (45.55%) or resting (36.52%). The grooming behaviors of female tarsiers (6.52%), including autogrooming and allogrooming, were also recorded. reported urination (4.11%), which exhibits sexual behavior (3.58%), eat (2.25%), vocalize (0.90%), drinking (0.30%), and defecate (0.24%). consumed more crickets (73.26%) than Hong Kong caterpillars (19.02%). Because the captive breeding facility was a semiopen cage, they could still prey on wild insects, such as flying white ants, moths, lizards, and spiders, coming to their cages (7.72%).

CONCLUSION

Based on these results, we confirmed that can express its natural behavior in a captive breeding environment. However, some activity budgets, including locomotion and resting, were greater in this study than in the natural habitats due to food source availability. Modifications to the animals' environments or changes in feeding methods may increase activity and behavioral diversity to more closely emulate wild populations.
