This photograph by Mary Weems was taken in the hollow. Not sure what kind of owl it is, but there is evidence of at least four types of owls in the hollow. We have heard the distinctive calls of three types of owls – the great horned owl (or hoot owl), the screech owl, and the barred owl. I also once saw a white-faced barn owl, in of all places, the barn. We have seen large owls flying that are either great horned owls or barred owls – the two largest species of owls found in this area. There are other owls around but I’m not able to recognize their calls with any confidence.
