Cleveland Metroparks Zoo is happy to announce the birth of two baby Francois' langur monkeys. The babies were born within two days of each other in The RainForest. The first baby was born on Wednesday to first-time mom, Mei Mei. The second baby was born early this morning to mom Petunia, an experienced mother who has given birth to four other offspring. Male langur Lang Son is the father of both babies. The Zoo has been very successful in breeding endangered Francois' langurs as part of the Association of Zoos & Aquariums' Species Survival Program - these are the 29th and 30th langurs born at the Zoo since 1990. SSPs are cooperative breeding and management groups for endangered or threatened species including black rhinos, lowland gorillas and African elephants. Mei Mei, 17, came to the Zoo in May 2005 from the San Diego Zoo where she was born. Lang Son, 20, was born at the Oregon Zoo in Portland. He arrived in Cleveland in November 2013 from the Kansas City Zoo. Petunia, 13, was born at Cleveland Metroparks Zoo in November 2000. The Zoo's troop of Francois' langurs now consists of seven monkeys. Mei Mei, Lang Son, Petunia, and the babies are on exhibit in The RainForest. The Zoo's other two langurs, both older juvenile offspring of Petunia's, are currently off exhibit. The Francois' langur is classified as "endangered" in the wild by the International Union for Conservation of Nature, the primary organization for quantifying conservation assessment efforts. The IUCN characterizes the population of wild Francois' langurs as "decreasing" due to habitat loss and hunting throughout its range of China, Laos and Vietnam.
