Bir

Bir belongs to the forested country of the upper Amur and its southern tributaries. Oroqen communities in the river valleys were known by names linked to the places where they lived; those along the rivers farther east were called Bilarchen. Hunting, fishing and gathering drew upon the forests and streams. In Qing times some Oroqen entered the Buteha banner organization, while others remained hunters required to supply sable pelts to officials sent to collect them.
