Temporal range: Early Miocene to Recent
A chipmunk is a small squirrel-like rodent. About twenty-three species fall under this title, with one species in northeastern Asia, one in the eastern portions of Canada and the US, and all the rest native to the western part of North America.
The name may have originally been spelled "chitmunk" (perhaps from a Native American word meaning "red squirrel"). However, the earliest form comes from the Oxford English Dictionary (in 1842) as "chipmonk". Other early forms include "chipmuck" and "chipminck".
