Undertook a bat survey at a mansion house last night with a fellow surveyor in North East Scotland. and were given this bat which they found on Sunday under a radiator in the drawing room. Assumed it was a Leislers but am wondering if it may be a Noctule. I cannot get the wings out to measure the wingspan but the forearm is 50mm and it weighs 20g, both of which are at the upper limit for Leislers It is a male with a long slim black penis. Any thoughts; its not often (never) that you come across these in northern scotland
