chital
The Chital (Axis axis), also known as the Spotted Deer or Axis Deer, is one of the most abundant and recognisable deer species of the Indian subcontinent. Males are distinguished by their elegant three-tined antlers, which can span over a metre, while both sexes display the species' characteristic reddish-brown coat spotted with white — a pattern retained throughout adult life unlike most deer, which lose spots after fawnhood. Chital inhabit grasslands, forests, and forest edges across India, Nepal, Sri Lanka, and Bangladesh, showing a strong preference for areas with access to water and open grazing clearings within or adjacent to woodland. They are highly gregarious, forming large herds in which males, females, and young associate freely outside the rut. Unlike most cervids, chital lack a fixed breeding season, and males are often in velvet or hard antler at varying times of year. They are important prey for tigers and leopards throughout their range and contribute significantly to the ecology of Asian ecosystems. The IUCN lists the species as Not Evaluated under current assessment standards, though it was historically assessed as Least Concern. Chital have been widely introduced outside their native range for hunting and deer farming, with feral populations established in Texas, Hawaii, Australia, and elsewhere.
