Surprised to see a pretty little Hermit Thrush here in the yard a few minutes ago - thought they'd long left the area; and interested to observe it vibrating or shaking its pink legs, sometimes left, sometimes right, sometimes so fast that its tail shook, too.  It would do that a few seconds, then dart and peck at something in the grass.  Could that be to stir up insects?
