American White Pelican, Pelecanus erythrorhynchos, flying low along the water in the Mission River Preserve. While frequently found in the interior of North America, these birds are less common visitors near the ocean. This one was found in a group of four birds. They were located about two miles inland from the mouth of the Mission River. I've only seen them there two or three times, as they tend to avoid the ocean on their annual Winter migration.
