Pippistrelle in trouble

A neighbour found this Pipistrelle clinging to the stone wall of their house and got in touch with me. I called out the local bat man who thankfully was able to come straight away to tend to this cold and probably unwell bat. I am waiting to hear how things transpired once he got it watered, fed and warm. It is a male Common Pipistrelle (Pipistrellus pipistrellus) but interestingly the pips around my house appear to be the Soprano Pipistrelle (Pipistrellus pygmaeus). UPDATE: Pip returned to site after feeding and watering and was seen 'scoffing insects' before returning to its roost.
