Axis deer most commonly occur in herds of ten to fifty individuals, with one or two stags and a number of females and young. They are often fairly tolerant of approach by humans and vehicles, especially where they are accustomed to human disturbance. They do not occur at higher elevation forests where they are usually replaced by other species such as the Sambar deer. Axis deer eat primarily grasses and vegetation, but also eat their shed antlers as a source of nutrients. The chital has a protracted breeding season due in part to the tropical climate, and births can occur throughout the year. For this reason, males do not have their antler cycles in synchrony and there are some fertile females at all times of the year. Males sporting hard antlers are dominant over those in velvet or those without antlers, irrespective of their size and other factors.
