Rodents are a diverse group that display a range of social systems. Cliff chipmunks (Tamias dorsalis) are documented as solitary across their range; however, we report here observations of communal denning outside of the breeding season in southeastern Arizona. We radiocollared and tracked nursing females and their offspring to locate nocturnal dens from June to October 2013 and 2014. We observed codenning in juvenile siblings, and juveniles and adults. Our social denning observations indicate that cliff chipmunks demonstrate behavioral plasticity.
