Axis porcinus

The Indian hog deer (Hyelaphus porcinus) is a small deer whose habitat ranges from Pakistan, through northern India, to mainland southeast Asia, which inhabits much of the Indo-Gangetic Plains of Pakistan, northern India, Nepal, Bangladesh, southwestern Yunnan Province in China, all the way to western Thailand. Introduced populations also exist in Australia and Sri Lanka. It gets its name from the hog-like manner in which it runs through the forests with its head hung low so that it can duck under obstacles instead of leaping over them like most other deer. Cover is taken as soon as it is feasible. During flight, the tail is held erect, showing the white underside.
