See my Guide to Photographing Pelicans in La Jolla.
Here are a few photos of California brown pelicans performing the pelican head throw, also known as the pelican bill throw. It looks painful. The brown pelican lifts its large bill up, arches its neck back until the throat gular pouch is stretched and taut, holds this position for a moment, and lowers its bill again. Sometimes it will open its jaw during the head throw, other times it will precede or follow the bill throw by bending its neck such that the throat pouch is turned inside out. Strange. Check out this bird, it is one of my favorite species and truly bizarre. I’ve seen one bird photo specialist refer to the head throw behaviour as “elusive”, however in my experience the head throw is quite easy to capture on film provided you are reasonably observant and can put your lens on the subject in a timely manner.

California Brown Pelican claps its jaws mandibles, sometimes rapidly several times, perhaps to dislodge debris or simply because its fun and feels good. This is not the same as the "yawn" that precedes a head throw. Adult winter breeding plumage with brown hind-neck.
