Twenty-four hour behaviour patterns and budgets of free-ranging reindeer in winter

Activities of free-ranging reindeer (Rangifer tarandus) on the Seward Peninsula, Alaska were studied to determine 24-hour behaviour patterns and budgets in winter. Use of daytime active-rest data to predict nighttime behaviour resulted in as much as 37% underestimate of nighttime resting and 37% ov...
