When I passed by at around 11 a.m., both Burrowing Owls were back in their habitual spots. The sun was working hard to break through a high overcast. The east owl looked like it was just settling into its position in front of the tombstone slab with the white dot. A Ground Squirrel crouched on top of the stone, followed by a Black Phoebe (not shown in the video). The owl ignored them both. Its behavior showed alertness, as it tracked various motions in its view; and then it quieted and its eyes half closed. Here is a short video:
A few minutes later I reached the north owl. It held quite still, apart from swiveling its head. A park visitor approached and looked at the camera screen while I was filming. The sound track captures her reaction.
