Today, November 7, marks the first day of winter (立冬, りっとう） according to the traditional calendar. Kumanichi reports that migratory birds have been flocking to Lake Ezu to spend the winter; apparently, some 3,000 birds of ten species winter in the area. You’ll likely see flocks in V-formation flying overhead; visit the lake in winter and the warmth of the water relative to the early morning air leaves it covered with a layer of mist. - William
