About the Knob-billed Duck
Also known as: Comb Duck, African Comb Duck, Knob-billed Goose, Nakta Duck

The Knob-billed Duck, scientifically known as Sarkidiornis melanotos, is a species of duck that is found in the tropical freshwater wetlands of Sub-Saharan Africa, South Asia, and parts of the Indian subcontinent. This species is instantly recognizable by the distinctive knob on the bills of the males, a feature from which it derives its name.

Inhabiting a variety of wetland environments, the Knob-billed Duck is adept at foraging both in water and on land. Its diet is quite diverse, including aquatic vegetation and a range of small invertebrates. This feeding versatility allows it to thrive in different types of wetlands, from lakes and marshes to flooded fields.

Visually striking, the males display a dark, iridescent plumage with white markings, while the females are more subdued in color, which helps in camouflage. The characteristic bill knob becomes more prominent during the breeding season, adding to the males' allure.

The Knob-billed Duck's widespread distribution across multiple continents speaks to its adaptability and the ecological significance of maintaining healthy wetland ecosystems. As a species, it highlights the importance of wetland conservation efforts in preserving not just its habitat but also the myriad of life forms that depend on these crucial ecosystems.
