This chipmunk arrived in my backyard last spring as a baby and has claimed it as his residence. Although his twin still visits regularly, he has not made himself as comfortable in my backyard as this little one has.
According to Animal Diversity Web, most Eastern Chipmunks only survive about 2 years in the wild, but they have been known to live for up to 8 years. I'm hoping that my chipmunk will be one of the lucky ones and will live for years in my backyard.
