Abstract

Studies the movements of Lagopus lagopus through the narrow valley of Anaktuvuk Pass in the Brooks Range, recorded since 1948. Migration from the breeding grounds in the Colville and other river valleys in the Arctic Slope begins in late Sept; movement northward from as far south as the Koyukuk River occurs in mid Jan-early Feb and again in early Apr. In winter adult males predominate in the northern range, juvenile males in the Pass, and females in the southern range.
