A baby rhino is usually referred to as a calf. A grown male rhino is called a bull and a female is referred to as a cow.
Female rhinos can have one baby every 3 years on average. The gestation period is 18 months, and the baby calf is born weighing approximately between 65 and 90 pounds. Within just a few minutes, the baby rhino can stand and will begin nursing from its mother within a few hours. The calf will continue to nurse for a year and a half, but it will also begin grazing long before that time. The baby will continue to stay with its mother for protection until it is about 3 years old.
