The remaining owl chose a new roost for the day in a tree just to the west of its previous tree. At fly out, it went to the hill between the nursery and compost, and most likely caught and ate a mouse. It then went to a pile of brush next to one of the compost dumpster and hunted before flying off to the west.
The real thrill of the night was seeing the pair of Eastern Coyotes who were making their way south along the path that goes between the compost area and the Conservatory Garden. They went then made a loop in the nursery. I had to leave early, but reports are the pair howled five times.
