Below, a short video clip of a Barn Owl roosting at a known nest site, just outside Duhallow this evening. While surveying buildings for the presence of Barn Owls a careful check is always made from outside, and sometimes you get lucky...
You can just see the Barn Owl as the camera zooms in. Walking straight into the building would probably have prompted the owl to slip unobtrusively through another exit and it might have gone unnoticed (Video: Michael O'Clery).
Enhanced screengrab of the latter part of the video clip.
