Whistling-Cock Indices and Bobwhite Populations in Autumn

Several investigators (Bennitt, 1951; Reeves, 1954; Rosene, 1957) indicate that whistling-cock counts of bobwhites (Colinus virginianus) in summer foreshadow bobwhite populations during the subsequent autumn and winter. Counts of whistling cocks in summer are represented as a reasonably accurate advance index of quail populations subsequently available to the hunter. This index cannot take account of
