Sika Deer

The sika deer is an East Asian deer whose reddish-brown summer coat is marked with white spots. In winter the coat becomes greyer and less conspicuously spotted, but the large white rump patch bordered by dark hair remains distinctive. Only males grow antlers, which may measure 30–80cm. Size varies greatly among regional populations: males measure 120–190cm and weigh 30–140kg, while females measure 110–160cm and weigh 20–90kg.

Sika deer favor forest and woodland containing grassy openings, although populations occupy habitats ranging from temperate forest to subtropical woodland. They are flexible mixed feeders, grazing on grasses, sedges and dwarf bamboo while also browsing leaves, shoots, bark, fruit and other seasonal plants. Adults may be solitary or form small groups. Males employ several mating strategies, including defending rutting territories or assembling harems. Gestation generally lasts 222–237 days, with most females producing one calf during May or June.
