I couldn't find either owl before fly out tonight. Although frustrating, I'm happy that they've both found more private places to roost. I had been in the teens the night before, so it's possible that they roosted together.
After walking all around the Loch, I found the female near Glen Span Arch. Then I found the male as well. He was fishing for her, while she called to him. He's gotten better at fishing. He brought her two treats within about fifteen minutes.
He went off into the woods, but she stayed near the stream for another half hour. After having been feed, I suspect she was in no rush to fly off.
The two blurry pictures in the set below are the male handing off his treats to the female.
