- Date: December-February, 2025
- Location: Endangered Primates Rescue Center - EPRC (Cuc Phuong National Park, Ninh Binh, Vietnam)
- Goal: Research and help to captive population management thank to ethology
The Endangered Primate Rescue Center (EPRC) in Vietnam, located within Cuc Phuong National Park, is dedicated to the rescue, rehabilitation, breeding, and release of Vietnam's critically endangered primate species. Facing threats like habitat loss and illegal trade, the EPRC provides vital care, conducts research, and raises awareness to protect these unique and vulnerable animals, contributing significantly to their long-term survival.
My presence was characterized by:
1) Assessment of the introduction of a new individual in a group
- Quantitative and Qalitative observation of the focal individual
- Biostatistics
- Writting repport
2) Standardising center's data:
- Documenting sexual dimorphism
- Documenting how to differenciate Red-shanked douc langur (CR) and Grey-shanked douc langur (CR)
- List of langurs' leaf diet & List of small apes (Gibbons) and lorises' diet given within the center.
3) Bring ethological observation in:
- Elaborating the ethogram of Red-shanked douc langur (CR) and Grey-shanked douc langur (CR)
- Elaborating of the vocalization diversity of Red-shanked douc langur and Grey-shanked douc langur,
- Elaborating an analyse of development stages (color and behavioral) of Red-shanked douc langur and Grey-shanked douc langur,
- Monitoring the first days of life of new born in the center to analyse if everything is going well. Focused species: Red-shanked douc langur (CR), Cat Ba langur (CR), Delacour's langur (CR) and Hatinh langur (CR).
- Monitoring to Delacour's langur (CR) in their semi-wild enclosure,
- Night monitoring lorises (Pigmy slow loris, bengal loris) in their semi-wild enclosure






Then, I had the chance to observe the red-shanked douc langur in the wild within the Son Tra Peninsula, central Vietnam...
