African Comb Duck - Sarkidiornis melanotos
This peculiar duck belonging to the species Sarkidiornis melanotos (Anseriformes - Anatidae) gets its common name from the large, fleshy, dark grey growth or ‘comb’ on the top of the male’s beak, an unusual and distinctive structure which enlarges during the breeding season.
Also known as Knob-billed Duck, the species has a wide distribution across sub-Saharan Africa, Madagascar, South and Central America, and tropical Asia, including Cambodia, China, India, Japan and Vietnam.
