Said to have become nocturnal to avoid contact with humans, the kouprey moves into the depths of the forest during the day, emerging at night into nearby grassland to graze. An active species, kouprey dig into the ground and the males butt tree stumps, causing fraying of their horns. Led by a single female, herds number fewer than 20 individuals and will travel up to 15 km in a night as they graze on grasses, visit saltlicks and drink from waterholes. Herds are known to break up and rejoin as they travel (2), and may also be found in mixed herds with banteng or wild buffalo (6).
Kouprey mate in the spring; females produce a single offspring in winter after an eight to nine month gestation. Females leave the herd to give birth, protecting the new-born calf amongst dense vegetation until it is about a month old when they return to the herd (2).
