The male white-tailed deer, sometimes known as a stag or buck, can weigh anywhere between 150 and 300 pounds on average. Female white-tailed deer, sometimes known as cows or does, can weigh anywhere between 90 and 200 pounds.
Young deer are referred to as fawns or calves, and they weigh between 4 and 8 pounds at birth. Generally, the age of a fawn may be determined by its spots, as fawns lose their patches by the age of four months.
By the time it is weaned, a fawn has grown an enormous quantity of weight. At approximately 4 months, the male fawn will weigh between 80 and 85 pounds, while the female will weigh between 75 and 80 pounds.
