But thanks to a decades-long effort led by local conservators and subsidized by the Japanese government, the number of red-crowned cranes in Mr. Yamazaki’s town, Kushiro, has swelled to about 1,900.

Last year, the bird — which appeared on the 1,000-yen note for nearly a quarter-century, serves as the logo of Japan Airlines and regularly features in artistic scrolls and New Year’s greeting cards — was reclassified as “vulnerable” from “endangered” by a worldwide conservation group. The new designation signals that the cranes are no longer at imminent risk of extinction. ...continue reading
