Black-necked cranes in Bhutan

Black-necked cranes in Bhutan (Grus nigricollis) are winter visitors during late October to mid February to the Phobjikha Valley as well as Ladakh, India, and Arunachal Pradesh, India. They arrive from the Tibetan Plateau, where they breed in the summer. They visit the Phobjikha Valley in large numbers, which is a declared protected area for the cranes, and also to other valleys in smaller numbers in central and eastern Bhutan.

On arrival in Phobhjikha they are seen to circle Gangteng Monastery three times as if practicing kora ("circumambulation"), and repeat this act as they begin their return to the Tibet Autonomous Region in early spring.
