Last night (Friday), I was walking around the Griffy Creek valley just before sunset. As I descended the ridge a Barred Owl, Strix varia, started hooting from the other side of the ravine, and continued for about 5 minutes. I walked into the main valley and was watching the sunset sky through the silhouetted trees, when I saw a large bird fly from one ridge to another, rounded wings tips leading me to think it was the barred owl. But soon the unmistakable sound of a great horned owl, Bubo virginianus, filled the valley. Soon a second started hooting, but a bit more quietly, from the other side of the valley.
They called back and forth for 15 minutes, moving ever closer together, each with its own particular tonality and resonance. They were still calling as I left the valley after dark, and as it seemed like date night in the valley, I was happy to leave them to their good times.
