I was tempted to give a Theme prefix to this one -- after all, the branches are bare of foliage, the birds are puffed up to stay warm in the frigid air, and the juvenile is molting into winter adulthood. But so many nice snowy scenes have been posted this month that I resisted the temptation. Anyway, I liked the juxtaposition of these two House Sparrows, sitting by the side of a pond near the Jersey Shore a few weeks ago.
