Chipmunks are a type of squirrel. The collective term chipmunk includes approximately 35 different types, spread for the most part throughout North America. Chipmunks inhabit forests.
They build extensive tunnel systems which link different chambers and entrances. They build sleeping and storage chambers in which these diurnal animals store food for the winter. In the winter these small rodents take a winter rest which they may interrupt several times when temperatures are mild.
