The pika survives where life is rocky. A male pika scurries across a stone pile high in the mountains. He nips leafy twigs off bushes and piles them in the shelter of a rocky den. This hamster-size cousin of the rabbit builds a hay pile as big as a bathtub. In the winter, he feeds on his hay pile, tunnels through the snow for lichens, and pops out for low-growing plants. The story of how the pika avoids predators, survives the cold, and sings for a mate will enthrall young readers.
