The
eastern chipmunk (
Tamias striatus) is a
chipmunk species found in eastern
North America. It is the sole living member of the
chipmunk subgenus Tamias, sometimes recognised as a separate
genus. The name "chipmunk" comes from the
Ottawa word
ajidamoonh or the
Ojibwe word
ajidamoo, which translates literally as "one who descends trees headlong."
