White rhinos spend about half of their waking hours eating and will eat up to 120 pounds of grass per day to sustain themselves. Rhinos will drink whenever and wherever they can find water but can survive up to five days without it. A group of rhinos is called a “crash.” Females and juveniles may be found in groups of more than a dozen animals.
Adult bulls are solitary animals that roam the savannah alone, seeking out females only to mate. Female white rhinos reach sexual maturity at about six years of age. A female rhino will give birth to a single calf about once every two or three years. The mother will nurse her calf for up to one year and the calf will remain with its mother for at least two years, learning from her and benefiting from her protection. Mother rhinos guard their young aggressively and can be daunting, dangerous adversaries if challenged. When a female rhino is ready to give birth again, she will chase away her first calf.
