Knob-billed Duck

Sarkidiornis melanotos

The Knob-billed Duck, also known as the Comb Duck, is a large, distinctive waterfowl species found in tropical wetlands of sub-Saharan Africa, South Asia, and South America. This duck is recognized by its unique knob at the base of the bill, which is more prominent in males. It has a striking black and white plumage with chestnut-brown accents, and its long, broad bill is adapted for filter-feeding on aquatic plants and invertebrates. Knob-billed Ducks are often seen in shallow freshwater habitats, such as marshes, lakes, and rivers, where they forage for food and breed in dense vegetation. They are known for their loud, trumpeting calls during courtship displays.
