Comb Duck - மூக்கன் தாரா.
The knob-billed duck (Sarkidiornis melanotos), or comb duck, is an unusual, pan-tropical duck, found in tropical wetlands in sub-Saharan Africa, Madagascar and south Asia from Pakistan to Laos and extreme southern China.
It also occurs in continental South America south to the Paraguay River region in eastern Paraguay, southeastern Brazil and the extreme northeast of Argentina and as a vagrant on Trinidad.
Comb ducks are usually found in single pairs or small groups (harems) during the breeding season, and in groups of up to 30 to 40 birds at other times.
The diet consists mainly of vegetable matter, such as aquatic vegetation, seeds of grasses and sedges, grain (including crops such as rice and corn), as well as various invertebrates, such as aquatic insect larvae and locusts.
Comb ducks usually nest close to water, in large tree cavities, holes in the walls of isolated buildings, abandoned nests of other birds, or sometimes on the ground.
The nest is a rough structure built from twigs and course grass and is lined with grass, leaves and feathers.
The breeding season is variable but usually coincides with the rainy season.
In some areas comb ducks are monogamous while in others males may hold small harems of two to four females, which they defend against other males.
Between 6 and 20 eggs may be laid, though nests sometimes contain the eggs of more than one female.
Incubation lasts 28 to 30 days and is performed exclusively by the female.
Within just a day or two of hatching, the ducklings leap from the nest, which may be up to 12 metres above the ground when summoned by the female.
