Generally, the average male (stag) Red Deer of Europe is 1.2 metres (4 ft) tall and weighs 295 kilograms (650 lb). European Red Deer tend to be reddish-brown in their summer coats. Only the stags have antlers which start growing in the spring and are shed each year, usually at the end of winter. Antlers are made of bone which can grow at a rate of 2.5 centimetres (1 in) a day. A soft covering known as velvet helps to protect newly forming antlers in the spring. European red deer antlers are distinctive in being rather straight and rugose, with the fourth and fifth tines forming a "crown" or "cup" in larger males. Any tines in excess of the fourth and fifth tine will grow radially from the "cup". Mature Red Deer usually stay in single-sex groups for most of the year. During the mating ritual, called the rut, mature stags compete for the attentions of the hinds and will then try to defend hinds that they attract. Rival stags challenge opponents by bellowing and walking in parallel. This allows combatants to assess each other's antlers, body size and fighting prowess. If neither stag backs down a clash of antlers can occur, and stags sometimes sustain serious injuries. Dominant stags follow groups of hinds during the rut, from August into early winter. The stags may have as many as 20 hinds to keep from other less attractive males. Only mature stags hold harems (groups of hinds) and breeding success peaks at about 8 years of age. Stags 2-4 years old rarely hold harems and spend most of the rut on the periphery of larger harems, as do stags over 11 years old. Young and old stags that do acquire a harem hold it later in the breeding season than those stags in their prime. Harem holding stags rarely feed and lose up to 20% of their body weight. Stags that enter the rut in poor condition are less likely to make it through to the peak conception period.
