Pelican Diving for Food

California Brown Pelican diving for fish in the Mission River, San Diego, California. Most pelicans dive from perhaps 50 feet up, diving at a near vertical incline into the ocean to catch fish. A few California Brown Pelicans have adapted to diving in much shallower rivers. They cruise over the water at about 4-5 feet scanning for fish and, upon spotting one, swoop headfirst into the water after them.
