Cotton Pygmy Goose (Nettapus coromandelianus)

The Cotton Pygmy Goose (Nettapus coromandelianus) is a small, brightly colored waterbird belonging to the family Anatidae. It is found throughout much of South and Southeast Asia, including India, Thailand, and Indonesia. The Cotton Pygmy Goose inhabits a range of wetland habitats, including marshes, ponds, and lakes, where it feeds on a variety of aquatic plants, seeds, and invertebrates.

Physical Characteristics:

The Cotton Pygmy Goose measures around 25 centimeters (10 inches) in length, with a wingspan of approximately 40 centimeters (16 inches). It has a distinctive, brightly colored plumage with a black and white head, a reddish-brown back, and a white belly. The bird has a small, pointed bill and short legs, which are set far back on its body, making it well-adapted for swimming.


The Cotton Pygmy Goose feeds primarily on aquatic plants, seeds, and invertebrates, such as insects, snails, and crustaceans. The bird is able to filter food from the water by using its bill to strain small organisms from the mud.

Reproduction and Lifecycle:

The breeding season for the Cotton Pygmy Goose typically occurs between March and June, depending on the location. These ducks are monogamous and form pair bonds that can last for several breeding seasons. They build a shallow nest on the ground near water, often concealed among vegetation.

The female lays 6 to 12 cream-colored eggs, which are incubated by the female for around 21-25 days. After hatching, the chicks are able to leave the nest almost immediately and are led by the female to nearby water. The young birds are able to fly at around 35-40 days old and become fully independent within a few weeks of fledging.

Conservation Status:

The Cotton Pygmy Goose is currently listed as a species of “Least Concern” by the International Union for Conservation of Nature (IUCN) due to its wide distribution and stable population. However, the bird could face potential threats from habitat loss due to wetland drainage, pollution, and other human activities. Conservation efforts focus on habitat preservation, monitoring populations, and reducing disturbances to nesting sites to ensure the long-term survival of the species.
