This chapter defines communal hunting as the organized channeling, concentrating, and killing of wild social herbivores using natural impediments and man-made structures that vary with hunting band size and herd. It talks about communal hunters who used natural or man-made channeling devices for intercepting migrating herds, and have ignored single hunters chasing seasonally disaggregated animals. The chapter organizes the descriptions of North American communal hunting starting with west Alaska, moving across Canada to east Greenland. It covers coastal Inuit groups before southern inland Indian bands in the order: Alaska, Yukon, British Columbia, Northwest Territories, Quebec, and Labrador. Barrenland communal hunting was emphasized in late summer and falls when large herds left the calving grounds bound for the forested winter range. Communal reindeer hunting in Eurasia will be discussed from west to east and from north to south, beginning with Scotland and France and continuing to Scandinavia.
