[FONT=Arial, Helvetica, sans-serif]Features:[/FONT]The Formosan sika deer is a medium-sized subspecies of deer measuring about 1.5m in length with a shoulder height around 98cm. They are named for the white, plum blossom-like spots on their back. Males are larger than females, with a shoulder height of 1m, and their antlers-which they start to grow at two years of age and continue to add one branch per year until they are five years old-can grow to more than 70cm in length. The smaller females have no antlers.[FONT=Arial, Helvetica, sans-serif]Behavior:[/FONT]The Formosan sika deer feeds mainly on leaves and tends to eat in the same area. They often rest at noon by either taking a nap under the trees or regurgitating the food that they've just eaten. A clean animal, they can often be seen in the springtime grooming their white fur while their light-chestnut or white-spotted summer coats are growing in. However, once their dark brown winter coats have grown in during the autumn, the males will roll about in the mud and dirty themselves in order to attract the attention of females. Formosan sika deer usually roam about on plains and in foothills. Sensitive by nature, they will go on alert at the first sign of trouble, setting their necks upright and opening their eyes wide. During their mating season in the autumn, the males will lock antlers and combat one another for a position of dominance and the right to mate.[FONT=Arial, Helvetica, sans-serif]Habitat:[/FONT]Formosan sika deer inhabit plains and mountainous areas at 300-500m elevations.
