What Is a Male Deer Called? From Buck to Stag

Deer are widespread animals that intrigue many people, leading to questions about the specific terms used for individuals within their populations. A common point of interest centers on how male deer are named, as these designations can vary based on age, size, and species. Understanding this terminology helps to accurately describe these animals in their diverse habitats.

The Primary Term for a Male Deer

The most common term for an adult male deer across many species is “buck.” This term applies to various deer, including white-tailed and mule deer in North America. Bucks are distinguished by antlers, bony structures that grow from their skull and are shed and regrown annually. These antlers are used during the breeding season, known as the rut, for competition and to attract females.

A buck’s antlers indicate its age and health, with size and complexity increasing as the deer matures. Beyond antlers, a mature buck exhibits a more robust body, a thicker neck, and a broader head compared to females, especially during the rut. White-tailed bucks, for instance, can weigh between 130 and 300 pounds. The term “buck” is broadly applicable, though more specific terms exist for certain species or stages of development.

Other Names and Species-Specific Designations

Terminology for male deer becomes more nuanced, reflecting age or species. A very young deer, regardless of sex, is called a “fawn.” Fawns are born between late May and early July, characterized by a spotted reddish-brown coat that provides camouflage.

As a male fawn develops, it may be called a “button buck,” a young male around six months old with small, nascent antler nubs (pedicles) on its head. These nubs are not yet true antlers but are the foundation for future growth.

For larger male deer, especially in Europe, “stag” is frequently used. This term commonly refers to a male red deer, a large species in Europe and parts of Asia, and implies a mature animal with impressive antlers. Stags are larger and stronger than bucks of smaller species.

The term “bull” is reserved for the largest deer family members, such as elk and moose. Bull elk can weigh between 700 and 1,100 pounds, and bull moose can reach up to 7 feet tall and weigh over 1,000 pounds, making them the largest deer species. These varied terms highlight the diversity within the deer family and the characteristics associated with their male members.
