Learning about Breeding
In March 1983, Ling-Ling and Hsing-Hsing mated successfully. Ling-Ling gave birth to a cub in July, but it died within a few hours. Over the next decade, although Ling-Ling had four more cubs, none survived. Zoo scientists worked hard to learn as much as they could about panda reproduction and health. |
