The Red Deer has long slender legs and a short tail. The tail is about fifteen centimetres in length. The Red Deer has a cream coloured round patch on its rump. It shows the patch to warn other Red Deer that there is danger in the area.

The male Red Deer is bigger than the female Red Deer and it also has antlers. The antlers can be over one and half metres long. Some antlers can branch off into sixteen points! The male Red Deer also has a mane of thick shaggy long hair which hangs from the front of the neck down to the chest. The mane usually grows in autumn.
