Zoo spokeswoman Judy Gagen says the pregnancy of a 30-year-old white rhino called Gloria was normal and nothing seemed amiss when she showed signs of going into labor Tuesday.
But when the female calf was born about 12 hours later it never took a breath, indicating that it died before birth.
Despite the sad outcome, zoo officials hope that Gloria will conceive again. Gloria has been pregnant nine times and has produced six healthy calves.
White rhinos are found in Africa, but they are an endangered species.
