In the broad, reed-lined wetlands of Africa and southern Asia, this dark-plumed heavyweight drifts across open water with unhurried authority. It feeds on aquatic plants, seeds, and small invertebrates, grazing steadily along marsh edges and flooded plains. What makes it extraordinary is its quiet influence on wetland health — by stirring sediments, trimming vegetation, and dispersing plant seeds as it moves, it helps keep shallow waters open and productive. A bold silhouette crowned with a striking knob, yet a steadfast caretaker of living wetlands.
