BEIJING, Dec. 19 (UPI) -- Chinese and European researches say they've discovered the breeding ground of an extremely rare bird in the mountains of north-central China.
Fourteen male Blackthroat Luscinia were observed in the Qinling mountains in Shaanxi province, which almost equals the total number of individuals of this species seen since its discovery in the late 19th century, a release from the Swedish Research Council reported Monday.
