No kidding--the first time I saw one here I thought I needed eyeglasses. The good news is that the white pelican does NOT do the spectacular dives of the coastal brown pelican, given that the waters are just not that deep around here. From same source as above: "This large snow-white bird is 50″–70″ long with black wing tips that can span up to 110″ (9ft.), their feet are orange, and webbed not only between the four front toes but also between the second toe and the inwardly directed back toe."
White pelicans are BIG.
