I have seen the northern flying squirrel in Nova Scotia kind of look like a cross between a red and a hamster used to see them when logging old timber and at night.or evening. Been a long time since I've seen one probably something to do with toilet paper and pulp. I have seen the southern flying squirrel in VA in the evening while bow hunting they're small like a big mouse.
The northern flying squirrels I have seen up close eyes about the size of a dime definitely nocturnal. Not close enough to the southern but I'm sure they're very similar.
Good luck and shoot straight all
