    Summary

    This study observed Malayan mouse deer behavior, detailing their alarm signals, scent marking, and reproductive patterns. Mouse deer exhibit primitive motor and social behaviors similar to other tragulids.

    Area of Science:

    • Ethology
    • Mammalian Behavior
    • Tragulidae Biology

    Background:

    • The Malayan mouse deer (Tragulus napu) is a small, forest-dwelling ungulate.
    • Understanding their social and reproductive behaviors is crucial for conservation efforts and evolutionary studies.

    Purpose of the Study:

    • To document the social and reproductive behaviors of a breeding colony of larger Malayan mouse deer.
    • To compare observed behaviors with known patterns in other tragulid species.

    Main Methods:

    • Direct observation of a breeding colony over a seven-month period.
    • Detailed recording of social interactions, vocalizations, scent marking, and reproductive events.

    Main Results:

    • Mouse deer exhibit foot stamping as an alarm signal and use inter-mandibular gland marking, with males marking more frequently.
    • Reproductive behaviors include male courtship of receptive and unreceptive females, post-partum estrus in females, and distinct maternal care patterns.
    • Agonistic behavior, including fighting with canines, occurs primarily when new individuals are introduced; behaviors are similar across tragulid species.

    Conclusions:

    • Malayan mouse deer display a range of social, reproductive, and defensive behaviors.
    • Their behaviors, including motor patterns, are considered primitive and share similarities with other tragulids, suggesting conserved evolutionary traits.
