On Wednesday, crowds gathered to say goodbye and catch one final look at Yang Guang and Tian Tian, who for 12 years have enraptured millions of visitors and residents of Edinburgh. “We’ve flown up for the day; we must be mad,” Lauren Darling, who recently visited the zoo, told The Telegraph. But American zoo officials and scientists said that it came down to biology, or “panda time,” since the three pandas should be going back to China because they are at an advanced age. A similar reason was cited by the Royal Zoological Society of Scotland. The pandas, the zoo said, arrived in Edinburgh in December 2011 as part of a 10-year arrangement between the organization’s charity and the China Wildlife Conservation Association, which allowed them to keep the pandas an extra two years because of the pandemic.
