Red Deer Stags (Richmond Park)

LONDON – OCTOBER 11: Red deer stags ‘rut’ in the early morning fog in Richmond Park on October 11, 2008 in London, England. Autumn sees the start of the ‘Rutting’ season where the large red deer stags can be heard roaring and barking in an attempt to attract females known as bucks. The larger males can also be seen clashing antlers with rival males. (Photo by Dan Kitwood/Getty Images)
