Leislers bat?

Observed: 30th July 2012 By: brillo
Bat
Description:

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

noctule

it looks to have the broad brown ears and distinctive mushroom-shaped tragus of a noctule but I'd want to see more pictures of the ears to be sure

Leislers do tend to have that

Leislers do tend to have that roughled 'mane' around the shoulders and, like noctules, have a mushroom-tragus.
