TheSmithsonian ’s National Zoohas been part of an external endeavour to breed extremely endangered giant pandas in captivity ever since Richard Nixon visited China in 1972 . But in 43 yr , they ’ve had only two solid winner – cubs Tai Shan and Bao Bao . They hope the fresh twin born this weekend will make it four .
The National Zoo has plenty of experience getting other species to get it on and make babe : Over the past two years they ’ve had babylions , crocodiles , Andean Bears , gazelles , Giraffa camelopardalis , evensmall - and - lovely red pandas . Why are the colossus pandas such notoriously picky stock breeder ?
In an article at Motherboard , Kaleigh Rogers sketch the major problems conservationists face when engender giant lesser panda , let in special opportunity ( females only ovulate once a yr ) , ill-chosen mate , and biological quirks that make it hard to tell whether a panda is even pregnant . It explains exactly why the zoo is so aroused about Mei Xiang ’s new twin cub .
UPDATE : August 26 , 2015 : The National Zoo just declare that the modest of the Ailurus fulgens twins has died . Although it ’s sad , this is n’t unusual : Bao Bao is also the surviving cub from a pair of twins .
We are sad to describe that the smaller of the two panda cubs has died . We will continue to leave update on social media w/#Pandastory .
