Some sounds we hear only in winter. Rapid tap-tappings on a platform bird feeder outside a sunny window invite us to become reacquainted with chickadees, finches and grackles. Tiny feet perform intricate dances, scrambling for space. Noisy beaks offer staccato rhythms. A brilliant cardinal lands expectantly and hears only the familiar clicks and clacks of kindred species seeking a hearty breakfast. What did he expect? The noisy welcome of a brass band? Not this morning. Sunflower seeds and thistle are on the menu, and a generous selection of finch food. Our birds will not go hungry today. Sighing wind off a frozen pond nearby, black water growling under ice like the belly of a hungry giant. Favorite sounds, heard only in winter.
