Yesterday at the marsh, the last day of winter (phew!), I saw my first robin of the season. It was hopping along the side of the trail, cocking its head as if listening for worms in the soil. Apparently they don't hunt by listening, but by sight. Since their eyes are on the sides of their heads, they tilt them and use one eye to look for worm castings in the grass, or the tunnels made by the worms.
