A family of chipmunks lives in Mother’s yard. My experience with these tiny burrowers is limited, so I’ve been enjoying their company.

I am most fascinated with their reaction to gray squirrels that browse the yard’s maple trees. Whenever squirrels are around, a single chipmunk will bark a raucous, staccato alarm. I can’t decide what the alarm’s purpose might be, as the squirrels and other chipmunks seem to ignore it. Perhaps this guard is a unique individual, exhibiting a behavioral quirk that is politely ignored by everyone except me?
