Every year, Kinga and his classmates wait for the black-necked cranes to return to the kingdom of Bhutan. The birds fly south over the highest mountains in the word to winter in the valley where Kinga lives, deep in the Himalayas. The cranes have been visiting the valley since ancient times, but every year, fewer cranes return. Kinga is concerned. "What can he do?," he wonders. He and his classmates approach the monks for permission to create and perform a dance to honor the cranes and to remind the Bhutanese people of their duty to care for them. The monks caution them to first watch the cranes to see how they move and learn from them. The children watch and practice. And practice some more until the big day when they perform before the king of Bhutan.Diana Cohn is an educator and writer with an active commitment to social justice work.
