I'm impressed with the research on this thread. K-Wise did a very fine piece of comparison. My first degree is in Zoology and I was simply too lazy to look it up, but with K-Wise's analysis, I fully agree. The Pika has no visible tail. Head and body of adults range from 6 1/5 to 8 1/2 inches. It weights 4 to 6 1/3 oz. They may be grayish to buffy or brownish. It omitts a series of short squeaks. It likes mountains, especially those with rock slides. It is found in Western Canada and all the Western states the U.S. as far East as Wyoming.
