These elegant flying birds are not seagulls. They are much larger, with enormous, comic beaks. They are brown pelicans.
On land, they look ungainly. In close up, some may even consider them ugly. The pouch under the beak is not very obvious, except when they are feeding.
But in the air, they are the epitome of sheer grace. Either individually, or in formation. In and around Pismo Beach in California, there are hundreds and hundreds of pelicans and other sea birds. They are just majestic sights.
It is impossible that such beauty can exist without a purpose.
