Chipmunk Squirrel Hybrid. They carry and hoard seeds and nuts. Your picture it appears the tail is wet so likely it's just a soaked rodent.
Another difference between ground squirrels and chipmunks is the kind of lifestyle they lead.
Tree squirrels and chipmunks are some of the most familiar members of the rodent order. Chipmunks are lively little creatures that are found mostly in north and west america with one species (asia's tamias sibiricus) native to eurasia. Physically, chipmunks are much smaller than most other types of squirrels, almost half even. It totally creeps me out, and i have no idea how to get rid of them.
