Seems to have inserted a couple of toes into the crack of our tongue and groove ceiling boards. It was sharing the front porch with a couple of Lesser Long-eared Bats, using opposite corners of the ceiling. When I checked again a couple of times later in the night none of them were present, so presumably they were just using it as a convenient spot for a rest from hunting. They have been doing it a lot in the last 2-3 weeks, with quite a dense scatter of bat poop collecting in the Long-ears' corner, and a smaller amount in the horseshoe bat's corner.
