The Lesser Yellowleg is an eating machine. It is constantly feeding on various things in the water and every 15 minutes or so it would hop onto a rock and poop. Then it would walk right back into the water and continue eating. There must be a lot of stuff in the water because it is contantly stabbing at the water with its long sharp beak.
