I always just called these squirrels Ground Squirrels but according to iNaturalist (an app you should definitely have on your phone) the species name is Douglas' Ground Squirrel. I don't know anything about Douglas, but I do know that another Douglas' Squirrel already exists and I don't want my photograph names to confused people. California Ground Squirrel is another common name for this species so I'll go with that.
