Third of three birds that were feeding is an unusual manner: the bill was held at a shallow angle, half-submerged, and the bill tips were vibrated or trembled such that bubbles and droplets of water emanated from around the submerged part of the bill. On a few occasions the birds then struck close to where they had been "bubbling", but I did not see them catch any prey. The three birds fed in this manner the entire time we were present.
