Abstract
Food caching and retrieving behavior by a red fox Vulpes vulpes was observed in a coniferous forest in Minami-Aizu, southern Fukushima, Japan, using a camera trap. The red fox hoarded food at the base of a tree on Oct. 30, 2022, 5:29 AM, and retrieved it on the same day, 6:49 PM (approximately 13.3 hours of hoarding). A raccoon dog Nyctereutes procyonoides visited the same site nine minutes after the fox left, and consumed leftovers remaining there. No interference was observed between the two canids. Although it was difficult to identify the nature of the food, it looked like some plant material (e.g., vegetable) or human food waste. Over the next two consecutive days, a fox and two raccoon dogs visited the site.
