The distribution of sun bears (Helarctos malayanus) is limited in China with very low populations in wild. The distribution of sun bear in Tibet is disputed, with only a single specimen recordfrom 1906. In the Second National Survey of Terrestrial Wildlife Resources, we photographed a sun bear in Jilong county, Tibet. The photo confirmed the existence of sun bears in Tibet, expanding its apparent distribution range, and we propose potential wider distribution region in China.
