Micro Troll or Mini Bat?

This bat, a common pipistrelle, had been sleeping in its cozy bunk bed between the logs on the outside of a cabin amidst a peaceful highland forest in Norway, teeming with berries, grouse, elk (in Europe, this means a version of the moose, i.e. it's not what Americans call elk!), bogs and trout lakes: here It was a bright and sunny July morning, nearly noon, and the creature didn't feel like getting up and taking off. But I was about to apply some resin varnish to the exterior walls of the cabin, so I just had to have this little troll move out.
