This American pika (Ochotona princeps) lives in a place with broken rocks called tallus.  At the edge of his rocky home, there is a mountain meadow, lush with plant material and food.
 
Pikas have a high energy demand as compared to many other montane mammals.  During the summer and fall, they may make 10-20 trips per hour to collect vegetation when haying. Every once in a while, they take a break, to replensh their energy by eating plant material.
