A thump in the night...

Last night we were in the darkened atrium watching The Rings of Power on Amazon Prime when suddenly, right in the middle of a very tense scene surrounded by orcs, there was a big thud followed by thumping up on the roof...

We were startled, turned on some outside lights, and went up to the loft to close the ventilation windows.  In the loft I could hear whatever it was cross from the east side all the way across to the west side as I was closing windows right below it...

Still have no idea what it was.  Our roof is a high-ceilinged 2-stories without external access except to flying creatures.  There are no squirrels or raccoons here.  There are monkeys in nearby mountains but I've never seen any in our little valley and the nearest tree is much too far a leap.  Don't know what kind of bird it could have been thumping around on an open roof in the middle of the night, but that's the most probable answer so far.  The preferred answer would be a flying squirrel gliding down from the surrounding cedar trees.  They do exist but they are rare and I've never seen one.  I would love to add flying squirrels to the menagerie that we have somehow organically developed here over the past few years--
​
Let it be a flying squirrel.  Please not goblins.  nor monkeys.
Fluffy Flying Squirrels would be delightful.  (I think)

UPDATE:
Climbed through the ventilation windows onto the roof this afternoon to investigate during the daylight...  I'm not Aragorn, but I'm pretty observant and I found nothing of interest to report.  So we are left with a mystery to be solved another time...

CASE CLOSED:
Last week's mysterious rooftop visitor returned to thump about again, this time with more urgency or desperation or mania...  but this time I was ready for action.  I turned off all the lights and pointed my big flashlight through the loft ventilation windows to catch a passing glimpse of the long tail and cute face of a masked palm civet.  A bit rare in this region and totally nocturnal, they look kinda like a raccoon-ferret-skunk hybrid.  Not a flying squirrel as hoped, not some large bird as expected, but also not a monkey, goblin, or orc...

A NEW CHAPTER:
Well, it's been about half a year, and the situation has evolved.  It turned out that our initial visitor was a masked civet jumping onto the roof from the nearby overgrown jungle trees.  Civets are cute, but very destructive to houses, and this one started scratching the roof maniacally trying to get in and live in our loft.  After several midnight visitations, I trimmed back the overgrown branches beyond its jumping range.  No more thumping in the night, and the surrounding forest had a healthier layering to the foliage.

A little later, we were visited by a badger who took shelter from a morning rainstorm UNDER the house.  Also quite cute, and also potentially destructive to the foundation, so after he woke up in the evening, we discouraged his returning by asking Alexa to play sounds of barking dogs and howling wolves...  which honestly felt a little silly.

Finally, six months later in the spring, a midnight thumping and skittering on the roof signaled a new arrival from the tall surrounding cedar trees.

And guess who?
Yes, at last, a Japanese giant flying squirrel.  Yay!
