A Sika Deer is a medium-sized deer, a subspecies of the red deer, native to much of eastern Asia. Since 2004 they have been introduced into parts of North America for sport hunting and as an attempt at introducing new genetic material into the dwindling population there.
For those that live closely with Sika Deer , their temperament can best be described as like most other members of the family Cervidae (deer) as shy and secretive animals.
They make great use of cover and will usually avoid running in open areas; this makes them particularly hard to hunt after the traditional European fashion. Their sense of hearing is acute and allows them fair warning before humans come too close, but their sight is poor beyond around 20 meters (65 ft). They are primarily grazers and need to be close to grassy cover. They will eat most types of vegetation, including crops if they can reach them, but seem particularly partial to salicornia where it grows near the seashore
