This little guy tries to sleep in the entrance to the house were I live. It is about 6 - 7 cm long and has the cutest little feet you can imagine. It was funny how it moved it's ear when the autofocus motor started to work. No wonder modern lenses have ultrasonic motors to adjust the focus.
If you look carefully you can see its eye how it is looking at you from behind its arm/wing.
I like its fluffy fur.
It could be a common pipistrelle, a Brandt's bat or a pipistrellus nathusii.
