Most babies were born underground in April, following a 31-day gestation. Little heavier than the air space they take up, the newborns weigh only one-tenth of an ounce and measure 2 inches, nose to tail. Males are available for breeding, but not for taking part in any domestic chores. They live a life of relative ease and irresponsibility when it comes to child care. Anyone who spends time in the woods knows the chipmunk has a varied vocabulary.
Studies indicate it's capable of producing four distinct sounds.
I've been in area woodlands at times when, it seems, every chippie is making sounds. My woodlot and yard wouldn't be the same without an irritated, animated chipmunk giving me a piece of its mind once in a while.
