American White Pelicans at Woodlake Pond in Carrollton, Texas.
Wikipedia has this to say about American White Pelicans:
They winter on the Pacific and Gulf of Mexico coasts from central California and Florida south to Panama, and along the Mississippi River at least as far north as St. Louis, Missouri. In winter quarters, they are rarely found on the open seashore, preferring estuaries and lakes. They cross deserts and mountains but avoid the open ocean on migration. But stray birds, often blown off course by hurricanes, have been seen in the Caribbean. In Colombian territory it has been recorded first on February 22, 1997, on the San Andrés Island, where they might have been swept by Hurricane Marco which passed nearby in November 1996. Since then, there have also been a few observations likely to pertain to this species on the South American mainland, e.g. at Calamar.
