I'm fascinated by pelicans simply because you don't see them in Michigan and they are everywhere out here, and for the most part they are HUGE. National Geo says they have a body of nearly 6 ft and a wingspan of 10 ft; that sounds about right. It gets your attention.
Watching them fish is really something. They circle above the water until they spot a fish, and then abruptly dive straight down, sometimes spinning in like a small aircraft shot out of the sky. Not much grace in the act, but it works for them.
Here's a shot of one I happened to catch in flight at Lake Merritt.
