I noticed holes dug in the lawn beside the walkway and wondered what had happened. Hours later I mentioned it to David, and he went out to look. At his suggestion, we viewed the video clips from the porch cam. There was the culprit, a skunk! He was active about three hours before I went out to walk. He could have been digging for beetles, crickets, or grubs. Skunks are nocturnal, so they are not likely to be out when I walk. Although the action is visible on my phone and computer, it is too dark to play here. The next day I took photos of the holes the skunk had dug.
