What is a Male Deer Called?

A male deer is called a buck. In some species, especially larger ones like the red deer, a male deer may also be referred to as a stag. The term ‘buck’ is commonly used for males of smaller deer species, while ‘stag’ is often used for larger species. Male deer are known for their antlers, which they shed and regrow annually. These antlers are used in mating rituals and fights with other males to establish dominance and win the right to mate with females.
