Young bucks lock horns at Phoenix Park
Rising testosterone levels among the herd of deer usually tend to fuel scraps between the bucks during the month of October.
Yet these fiesty bucks are feeling energetic - despite the time of year - and are vying to emerge as dominant to claim the affection of onlooking does.
Three species of deer live wild in Ireland today: fallow deer, red deer and the sika deer.
The wild fallow herd at the Park normally graze on the 200-acre flat meadow area known as the Fifteen Acres.
