Probably flying squirrels.  Sugar gliders are found in Australia, Indonesia, and New Guinea.  I've seen flying squirrels at my sunflower and peanut feeders.

We have more deer in our city than people, so I suppose it's a possibility. Feeders are on a 2x2 foot platform on top of a 4x4 inch post.  I wouldn't think raccoons could climb around the platform.  Maybe?  What possible nocturnal critters are emptying my feeders?  I can't stop them if I don't know what they are!!  What am I missing here?
