The Fallow Deer (Dama dama) is a ruminant mammal belonging to the family Cervidae. This common species is native to western Eurasia, but has been introduced widely elsewhere. It often includes the rarer Persian Fallow Deer as a subspecies (D. d. mesopotamica),while others treat it as an entirely different species (D. mesopotamica). The male is known as a buck, the female is a doe, and the young a fawn. Adult bucks are 140-160 cm long and 85-95 cm shoulder height, and 70-100 kg in weight; does are 130-150 cm long and 75-85 cm shoulder height, and 40-50 kg in weight. Fawns are born in spring at about 30 cm and weigh around 4.5 kg. The life span is around 12-16 years.
