A week or two ago, I enjoyed watching a young otter, grooming and snacking, on the banks of my home pond. The next morning, when I peered out my windows, it was clear that the otter had come back, leaving a furrow in the snow, across the frozen pond, under my front-entry deck, and around the house. A few days later, it was back, scouting around the house and garden and checking out the pond, leaving a new furrow in the snow. Perhaps it has a regular (but temporary) route it follows, revisiting places where foraging has been successful in the past.
