LANSING, Mich. – The Potter Park Zoo in Lansing is celebrating the birth of a black rhino calf. Doppsee, the zoo’s 12-year-old black rhino, gave birth to her first calf at 5:40 a.m. on Christmas Eve. There are just over 50 black rhinos in the care of AZA accredited zoos, according to Potter Park Zoo. “This is a monumental moment for Potter Park Zoo that has taken our staff years of planning and hard work. We are dedicated to conserving rhinos and couldn’t be more excited about this successful black rhino birth,” said Cynthia Wagner, Director of Potter Park Zoo.
