The red deer stag is the male of the red deer species, known scientifically as *Cervus elaphus*. These stags are characterized by their impressive antlers, which can grow up to 1 meter long and are shed and regrown annually. They typically inhabit forests, grasslands, and mountainous regions across Europe, Asia, and parts of North Africa. During the mating season, known as the rut, red deer stags engage in vocalizations and displays to attract females and establish dominance over other males. Their diet mainly consists of grasses, leaves, and shrubs, making them herbivorous grazers. The red deer is a significant species in ecosystems and is often associated with wildlife conservation efforts.
