Across broad lakes, floodplains, and slow-moving rivers of sub-Saharan Africa and South Asia, this imposing waterfowl moves with unhurried authority. It feeds on aquatic plants, seeds, and small invertebrates, grazing in shallows and resting in large, watchful flocks. What makes it extraordinary is the male’s prominent bill knob — a bold, dark swell that signals dominance during breeding season. Yet beyond the display, it helps cycle nutrients through wetlands, linking open water and grassy shores in quiet balance. A strong silhouette against reflective waters, yet a steady custodian of expansive marshlands.
