DULUTH, MN (KDAL) - The Lake Superior Zoo in Duluth is doing its part to assure the survival of the Angolan Colobus Monkey. A second baby monkey was born on July 16th and is now on display with a baby born three weeks earlier at the zoo. The new baby is the offspring of Kero, an 11 year old female and Kramer an 18 year old male (also the father of the other little monkey). The monkeys are the 5th and 6th born in captivity in 2013 as part of the Association of Zoos and Aquarium's Species Survival Plan. The young monkey are interacting with each other and are in an exhibit together with their parents. The Lake Superior Zoo is at 7200 Fremont Street in Duluth.
