It used to stress me when they went up the trees. I leave them up there now if they don't come down for supper. Young Rip spent weeks living in a tree just outside my front door.My only ever tree hugger was a Banty. She'd go to the top of my Poinciana for the night. She was a right pest!
If it wasn't for complaints from the main house, I would leave those who wanted to roost in the trees up there.
