Congratulations to Nashville Zoo on its newest arrival — a baby male Masai giraffe. The calf made its debut on Friday, Feb. 10, weight 163 pounds and standing six feet, three inches tall. Zoo officials report mother Margarita and the baby are doing well. They are currently off exhibit in the zoo's giraffe barn. This new little one is Margarita's fifth calf and the second male giraffe born at Nashville Zoo. "Margarita is a proven and successful mom for her calves, and this calf was no exception," says Greg Peccie, director of animal operations. "Once the calf was on the ground, she places her legs around him to help support him in his attempts to stand. The calf was standing with mom about an hour after he was born and proceeded to nurse almost instantly," he adds. The baby giraffe's name is Mazi (pronounced MAH-zee), which is short for Mazingira Maguma, Swahili for "vulnerable." With the addition of Mazi, Nashville Zoo is home to four Masai giraffes. Zookeepers are monitoring Mazi's development and will decide on his public debut depending on weather and temperature.
