Индийский водорез Rynchops albicollis

Unmistakable; black above and white below with bright orange bill (lower mandible longer than the upper). Favors slow-moving rivers with sandbars, on which this species forms noisy colonies, often in association with terns. Flies rapidly on long angular wings, “skimming” the water with the extended lower mandible. Gives a sharp “kip kip.”
