Female buffaloes are called cows. They stand approximately 5 feet tall and weigh 1,000 pounds, compared to bulls at 6 feet tall and 2,000 pounds. Females gestate for approximately 258 days, give birth to one calf a year and nurse offspring for six months. Buffaloes live as families in herds.
Female buffaloes have a life span between 20 and 25 years. Known as bison, buffaloes belong to the bovine family, which includes cattle and oxen, and they eat plants and chew cud. Bison are the largest land mammals in North America. Despite their large size, they can jump more than 6 feet and run up to 40 miles an hour.
