• Cultural Significance:
• Folklore: Holds special place in Malagasy culture, often considered taboo to hunt due to ancestral beliefs.

  • Communication: Vocalizations include bugling by males during the rut (mating season) and various calls by females and calves.
  • Diet: Herbivorous, feeding on grasses, leaves, bark, and plants.
• Reproduction:
  • Breeding Season: Rut occurs in the fall (September to October).
  • Gestation: Approximately 8.5 months.
