This little guy and a bunch of his friends were quite active along the talus slopes of the top of Montgomery Pass, Colorado in recent days. My son and I spend a good bit of time watching these entertaining creatures run around above timberline. It is said this species of pika may become a victim of a warming climate. Studies suggest the American Pika is being driven to higher elevations in search of cooler temperatures. As it moves higher however, it could eventually run out of places to go.
