The Red Deer is active throughout the day, although in areas with much human activity, it is more likely that they turn up early in the morning and late in the evening. In the morning they usually move to grasslands to graze there. Red deer live in all sorts of areas, from dry deciduous forests and heaths to very moist environments as bogs and swamps. Only the male animal has antlers, which may become as large as 90 cm, weighing from 8 to 20 pounds. By the antlers one can approximately read the age. A young deer usually has smaller antlers with fewer tines, as well as deer in their last stage of life. A healthy animal has bigger and heavier antlers, but not necessarily with more tines than a sickly animal. There is a clear link between the quality of the habitat and the size of the antlers. In the17th century antlers were large, with 24 or more tines, but from then on population pressure, hunting and the planting of pine-forests, demanded their toll. After centuries of decrease the antlers of the red deer on the Veluwe in Holland got bigger again, because their living conditions improved after the second world war, by laying out wild fields, planting deciduous woods and promoting forest undergrowth.
