In October each year, communities in the mountainous parts of Northeast India, gather in anticipation of the arrival of a small grey bird, the Amur Falcon, which annually migrates over 30,000 km.

For many decades, Amur Falcons (Falco amurensis) have been known to congregate in Nagaland, northeast India for a short period from mid-October to mid-November each year. The state appears to be a stop-over site during their annual migration from breeding grounds in Russia, China and Mongolia, to wintering areas in Southern Africa. Details have always been sketchy primarily because Nagaland was a closed state, with very few outsiders allowed access.
