About twice a year large flocks of pelicans are seen flying up or down the Mississippi River near Elsah, IL. This particular day the sun was out, the sky clear and I think the birds were just enjoying the day flying. They flew back and forth across the river picking up a good updraft as they came over the bluffs. They flew silently around and around. Unlike the geese that make a mighty racket as they fly by. I think geese like to make lots of noise. The pelicans are silent fliers.
