Researchers dressed in panda costumes

Researchers dressed in panda costumes try to approach giant panda Taotao and its mother Caocao in Wolong National Nature Reserve, on October 7, 2012. Taotao and its mother Caocao were transferred down from a 2,100-meter high mountain to Hetaoping Research and Conservation Center for a health examination and to be prepared for reintroduction to the wild. Researchers wore the costumes to ensure that the cub's environment was devoid of human influence, according to local media.
