Cheetah cubs born yesterday! Carnivore keepers at the Smithsonian’s National Zoo and Conservation Biology Institute (NZCBI) in Front Royal, Virginia, are celebrating a litter of five cheetah cubs born to 8-year-old adult female Echo Tuesday, Sept. 12. Viewers can enjoy watching the cubs grow via the Cheetah Cub Cam. Note that Echo may move her cubs out of the den and around her habitat so they may be out of view at times. Animal care staff will leave Echo to bond with and care for her cubs without interference, but as opportunities arise, staff will perform quick health checks. During a recent weight check, staff confirmed there are three males and two females. The cubs appear to be strong, active, vocal and eating well. About Echo and Her Cubs: Five surviving cubs were born Sept. 12 (a sixth cub did not survive). She is a second-time mom; Echo had a litter of four cubs in 2020. Echo was born at White Oak Conservation in Florida in 2015. There are two potential sires, either Asante or Flash; scientists will perform genetic testing to determine the sire when the cubs are old enough to have blood collected. Echo is trained for ultrasounds, which allowed staff to determine she was pregnant July 28. The cubs’ genetic data is important for population management as the cubs will eventually enter breeding programs. NZCBI is part of the Cheetah Breeding Center Coalition—a group of 10 cheetah breeding centers across the United States that aim to create and…
