I can't tell which specie, but will attach two photos. Perhaps you can identify them?
I'm not sure they are the same kind. The ears look much bigger on the flying one, but perhaps that's just a difference between adults and juveniles, or something like that?
One was found dead under the window sill, where you can spot the thin space between the bricks and house structure.
The other is from a shot out on the porch where they often fly by.
