The birth of a critically endangered Eastern black rhino is cause for celebration this month at a zoo in Ohio.

Cleveland Metroparks Zoo announced last week that the male calf was born on Saturday, Sept. 13, and remains behind the scenes bonding with his mother, 22-year-old Kibibbi. His father is 25-year-old Forrest.

At birth, black rhino calves can weigh 65 to 100 pounds, according to Save the Rhino . They can stand within the first few hours. They nurse for about two months, but sometimes up to a year, and stay with their mother for two to four years.

Adult black rhinos weigh about 2,000 to 3,000 pounds and stand over 5 feet tall at the shoulder, according to Save the Rhino.
