In the alpine regions, mountain goat, bighorn sheep, marmot and pika are widespread. The American pika is intermediate in size among pikas. Among smaller animals, marmots, hares, and several types of pika and vole are common. The American pika is a generalist herbivore. Predators of the pika include eagles, hawks, coyotes, bobcats, foxes, and weasels. The Ili pika somewhat resembles a short-eared rabbit. Also found is a member of the rabbit and hare family, the pika. This is a territorial call that informs neighboring collared pika of haypile possession. An adult large-eared pika is long. The Ili pika has low population densities. One species of pika occurs in California. Jean-Denis Vigne found clear evidence that the Sardinian pika was hunted and eaten by people. In general it is restricted to higher altitudes than the Alpine pika. It was named after Pika Peak, a mountain in Alberta, Canada. There are no known conservation measures in place for the Ili pika.
