Pelicans?

After I finished my run this afternoon, I sat in my car and nibbled on a high protein energy bar. I saw several birds flying in a circle above the Jordan River; the circle was slowly drifting southward. The birds weren't ducks or geese, and I think they were Pelicans. They were too far away for me to be sure, but they had the color of the Pelicans I saw about a year ago in one of the nearby fishing ponds (white body and black on both wings). I watched them for about a minute, until they disappeared from my site. The following picture was taken from the web.
