We'd heard them calling for a few minutes, then we spotted one in a tree. It was dusk, so I shot a bunch of frames, full zoom, wide open, hoping to get lucky. The first photo is the best from that night. Then two nights later we heard them again. They were quite cooperative, posing in the trees right above our deck, with the sun still up. The last is one of them departing.
They appear to be Barred Owls, juveniles, according to their call
