When I returned to Louisiana in 2001, seeing a Black-Bellied Whistling Duck was rare. Since then, the population has rapidly increased to the point that it is the most common duck I see. Originating in Mexico and Central America, they have migrated to Louisiana in large numbers. I often see them in the neighborhood perching on rooftops when I walk the dog. On my photo tours, we often have the opportunity to photograph these beautiful ducks.
