A spot-billed pelican scoops a bill full of water to carry back to its chicks in the nest. As it scoops the water, it rushes into its lower pouch which causes drag and the head snaps back with the weight of the onrushing water. This cause the head to snap back momentarily. I waited for this moment and made this image as the water dribbled out of its bill, as it dragged its head back to normal.
