ROCKIN' ROBIN - An American Robin stands on a small rock to get just that little bit of extra height as it scans the yard for food. Hunting Robins move in short bursts across the ground - running or hopping forward, then standing upright, often cocking its head to one side. It seems like they are listening for worms, actually they are watching the grass and soil for signs of activity as they hunt their favorite food - earthworms.
