The Red deer is the largest mammal in Britain and has been here in some form or other since this island was joined to mainland Europe. Red stags can appear the most majestic of animals when they are carrying a full 'rack' and the thick mane that appears during the rut.

During the summer, Red deer are dark red or brown with a lighter color of cream on the underbelly, inner thighs and rump. There may also be some spots on the summer coats, particularly along the spine. In winter, the pelage changes to a darker brown or grey, with lighter patches on the rump and undersides.

Currently, 1000 Red deer are living on the Alladale Reserve.  Numbers have been reduced over the last three years to allow natural forestry regeneration with very successful results.
