Eastern Chipmunk

Maximum longevity: 9.5 years (captivity) Observations: These animals have been known to live at least 2-3 years in the wild (Ronald Nowak 1999). One specimen lived 9.5 years in captivity. Another specimen of unknown sex lived over 9 years at London Zoo but could have been older because the exact date of birth is not known (Richard Weigl 2005).
