October: Feeding on the Fly
October is the month of heaviest migration. Most robins fly south in winter; however, some stick around—and move around—in northern locations where food can be found. The robins that stay will have the advantage of first choice of best territories in spring. Meanwhile, migrating robins find plentiful berries all along the journey south. Robins don't migrate on a particular route but fly in flocks, looking for food. Down feathers grow under outer feathers, adding extra insulation against winter's cold.
