The sole difference between “buck” and “stag” is that “buck” refers to a larger animal. All male deer are called bucks, although a huge male deer is occasionally called a stag.
Deer belong to the family Cervidae, which also includes elk, moose, reindeer, white-tailed deer, black-tailed deer, and red deer. They are found on every continent excluding Antarctica and Australia. Male and female deer terms vary significantly and are sometimes determined not by species but by size. For the majority of deer species, males are known as bucks and females as does. A stag is only a huge male deer, however this phrase is not universally employed. Males of some larger species are referred to as bulls and females as cows.
Additionally, deer terminologies can vary by age group and rarely by species. The male red deer is called a hart, while the female is called a hind. Again, these phrases are not conventional, and they apply notably when the male is older than five years and the girl is older than three. The terms hart and hind can also apply to species of deer other than the red deer. In the Middle English language, “deer” meant any species of wild animal, while “cattle” meant any species of domesticated animal employed as livestock. Not until much later did the term “deer” come to refer to the Cervidae animal with which it is now synonymous.
