It is the largest of the wild herbivores of the Iberian Peninsula, with a weight that can reach 200 kilos, a length of up to two meters and a height to the cross of between one and a meter and a half. It presents a clear sexual dimorphism, with males being more voluminous and presenting horns most of the year (except between February and May, when they lose them). Females on the other hand are more slender and lack horns at any stage of their lives. Deer can be found in a wide variety of habitats all over the Peninsula, from mountain systems to dense forests or dehesas. The heat period is in September and early October. Male deer mate with several females for which they must first compete with other adult males. During this period of zeal the crow reaches its highest development, the males fight by clashing their horns and emit large bawls in what is called the cress, which is easy to observe as their habits become diurnal and they become less skittish. Outside the breeding season males live isolated and itinerant and females live in colonies, along with subadults. The deer feeds on tender shoots and leaves, grass, shrubs, mushrooms and occasionally crops.
