Pikas (Ochotona princeps) were trapped at Mount Evans, Colorado, and were held captive in individual cages and in two 1-acre enclosures near Fort Collins, Colo. When pikas were released into the enclosures in July and August territorial battles resulted, but when released in May and June, combats did not occur. However, the number of chases per pika-hour was as high in the spring as during July and August. Pikas collected vegetation for their haystacks and constructed trails through the vegetation in the summer and tunnels through the snow during the winters. In general, their behavior in the 1-acre enclosures appeared similar to that observed in their natural habitat.
