Their large ears are distinctive. White-tail deer are tan in color, with a larger tail. In this fashion, they can reach a speed of 45 m.p.h. for short periods. The throat patch, rump patch, inside ears and inside legs are white with lower portions running cream to tan. A dark V-shaped mark, extending from a point between the eyes upward and laterally is characteristic of all Mule Deer but is more conspicuous in males.
Males are larger than females.
The bucks' antlers, which start growth in spring and are shed around December each year, are high and branch forward, forking equally into 2 tines with a spread up to 4 feet. Mule Deer have no canine teeth and, like the cow, have a multi-part stomach, the first two chambers of which act as temporary storage bins. Food stored here can be digested later when the deer chews its cud. Vocalization Deer are not especially vocal, although young fawns bleat on occasion. The tail is usually tipped in black with a white basal portion, and its under parts are white.
