Problem is being cold blooded he's still not gonns be that obvious.
IR goggles used directly after the sun sets would actually be a fantastic idea. He will retain more heat than the foliage through the night and the difference should be biggest about 30 minutes after there is no more direct sunlight when there is still dusk light he may still be active generating heat that the foliage will not.
I stared for hours and looked over pictures with nothing definitive. I wish I was closer I am generally very good at finding things...
