Baby a happy surprise after mom’s miscarriage in May. Scientists at Cincinnati Zoo & Botanical Garden’s Center for Conservation and Research of Endangered Wildlife (CREW) have devoted years to studying red panda reproduction and, in 2015, were the first to accurately predict birth dates for two cubs, born six days apart, using a combination of ultrasonography and hormone monitoring. By performing regular ultrasounds on super mom Lin, they were able to detect that she was pregnant in April of this year, but sadly the pregnancy was lost in May. Since red pandas are seasonal breeders, the team assumed that Lin would not be giving birth this year. But, two weeks ago today, she did!
