On a March afternoon, there are so many pandas in the ?kindergarten pen? at Wolong Nature Reserve in China?s Sichuan Province, it?s hard to keep track of their antics. One is attempting a handstand while three others are playing king of the hill. These carefree cubs ? a record 19 from Wolong?s 2006 breeding season ? are part of the dramatic comeback for a symbol of conservation: the giant panda.
