A typically solitary animal, the chousingha is a normally found at low density of 0.2 to 3.6 individuals per square kilometre (8) (10), although it is sometimes seen in groups of up to four individuals (8). In captivity, mating takes place during the rainy summer months from July to September (5), and throughout this time males become aggressive and rut, using their unusual horns to fight for their right to mate (6). Female chousinghas typically give birth to between one and two individuals, each weighing around one kilogram, after a gestation period of between 7.5 and 8 months (5). In captivity, the chousingha has lived for up to ten years (8).
The chousingha is a browser that lives on a diet of shoots, leaves, bulbs, fruits and flowers (4). It is believed to be dependent on water and must drink regularly in order to survive (5). A secretive and wary antelope, the chousingha will often freeze rather than flee when a threat approaches. This threat may be a tiger (Panthera tigris), leopard (Panthera pardus) or dhole (Cuon alpinus), all of which have been known to prey on the chousingha (8).
