About Evening Bats
One of the most distinct features about the Evening Bat, Nycticeius Humeralis, that you may notice is that it looks almost exactly like a Brown bat. While the Evening bat is quite a bit smaller than the Big Brown bat, the glossy brown fur, black face, feet and wings give it the impression that it could be a baby brown bat. Upon closer inspection though, you will notice that the Evening bat reaches only about four inches long with a wingspan of about eleven inches.
