Nothing encapsulates the sound of autumn better than the roar of a red deer stag in his prime. October is undoubtedly the best time of year for watching red deer as they fiercely fight for the chance to pass on their genes. The rut is now in full swing at Lyme Park and the next few weeks will present fantastic opportunities to witness this awesome wildlife spectacle first hand.

Here are some key facts about the red deer rut and what to look out for over the coming weeks:
- In order to gain exclusive mating rights, dominant stags form ‘harems’ - groups of several females (hinds) - which they will fiercely defend as the hinds individually come into oestrus (oestrus being the period of sexual receptivity when successful mating can occur).
- In red deer oestrus is triggered by the shortening of the daylight period, which is why the rut takes place at this time of year.
- Obviously it is the ambition of every stag to hold his own and preferably the largest harem but there are only so many females to go around. To maintain control of a harem, a dominant stag must therefore persistently drive away rivals. Dominance between rival stags is determined through a combination of one or more of the following:
- Roaring - By repeatedly bellowing a deep resounding roar, dominant stags are broadcasting their superiority and warning other males to stay away from their females (see video below).
- Parallel Walking - Rival stags will often engage in an intense walk to determine which of them is the largest. Moving in parallel, their gait will be slow and steady and they will often raise the hair on their backs to make themselves look bigger.
- Fighting - Fighting can occasionally result in serious injury or death. Therefore, rival stags will only willingly engage in a fight if they cannot determine dominance by other means. Contact will be initiated by one of the stags lowering his antlers. Antler locking quickly follows and the two stags will push each other back and forth until one of them is driven rapidly backwards and loses the contest. The video below was taken last week and shows two of our dominant stags engaged in a fierce dual.
- Despite the obvious magnificence of their antlers, it is the red deer stags ability to roar which holds the key to attraction. Females will often choose the male with the lower roar as they tend to be the larger bodied stags, which indicates strength and good health. It may sound unromantic but it makes perfect biological sense.
- During the rut stags will often appear much darker as they will regularly wallow in their own urine. The odour from the urine also helps bring hinds into oestrus.
- Given half a chance, smaller stags will attempt to move in on harems and mate with females. These opportunities usually only present themselves as the rut progresses and when a dominant stag is either in battle or exhausted from a recent fight.
Attacks on humans are extremely rare but please mindful that the stags are currently pumped full of testosterone and much more aggressive than at other times of the year. So if you do manage to get out and see the rut here at Lyme then please keep a safe distance and remember to keep dogs under close control. Having 200 kilos of angry stag hurtling towards you would not be an advisable experience!
