In southern India, it is called “pittai” or “pittri” in Tamil, while “kothiwai” or “kadu” are common names in Malayalam.
Family and Phylogeny
The Indian Spot-billed Duck is a member of the Anatidae family, a diverse group of waterfowl that includes ducks, geese, and swans. Anatidae is a globally distributed family with over 150 species, and the Indian Spot-billed Duck belongs to the subfamily Anatinae, which comprises true ducks.
The duck’s genus, Anas, is one of the most speciose in the Anatidae family, with over 50 species. Anas ducks are typically characterized by their dabbling behavior, where they feed by submerging only their heads and necks to reach aquatic vegetation. The Indian Spot-billed Duck is closely related to other Anas species, such as the Northern Shoveler and the Gadwall.

Feeding Ecology
The Indian Spot-billed Duck is a versatile and opportunistic omnivore, adapting its diet to the availability of food sources in its wetland habitat. Its primarily herbivorous diet consists of aquatic plants, grasses, and vegetation. The duck is adept at submerging its head and neck to uproot underwater vegetation, which it consumes in large quantities.
In addition to plant matter, the duck also feeds on small invertebrates and insects. It dabbles in shallow water, using its specialized bill to filter out small aquatic organisms. The duck may also prey on larger insects, such as dragonflies and beetles.
The Indian Spot-billed Duck has a flexible feeding strategy. During the breeding season, when protein requirements are higher, it may increase its intake of small animals to support its egg-laying efforts. The duck’s adaptable feeding behavior enables it to thrive in various wetland environments, ensuring a reliable food supply throughout the year.
Breeding Behavior of the Indian Spot-billed Duck
The Indian Spot-billed Duck embarks on its breeding journey during the monsoon season, when water bodies are brimming with life. These ducks exhibit a unique courtship ritual, where the male duck swims in a circle around the female duck, flashing its distinctive white wing-speculum and uttering soft calls.
Once the female duck accepts the male’s advances, they embark on a joint quest for a suitable nesting site. Nest construction is primarily the responsibility of the female, who meticulously weaves together plant materials in a concealed location among dense vegetation. The nest resembles a shallow bowl, lined with soft materials like feathers and down.
The Indian Spot-billed Duck typically lays a clutch of 8-12 eggs, which are incubated by the female for 24-28 days. During this period, the male remains close by, providing protection and occasionally assisting with incubation duties. Hatchlings are altricial, meaning they are born helpless and rely heavily on their parents for survival.
The ducklings, covered in soft down feathers, are precocial and can follow their parents to water within a few hours of hatching. Both parents play an active role in caring for the young, leading them to food sources and guarding them against potential threats. The ducklings remain under parental care until they are fully fledged and capable of independent feeding and flight, usually at around 50-60 days of age.
Conservation Status of the Indian Spot-billed Duck
The Indian Spot-billed Duck holds a vital place in the avian ecosystem, but its existence is confronted with significant challenges. The *IUCN Red List*, the global authority on conservation status, has classified this species as Vulnerable, highlighting the critical need for conservation efforts to safeguard its future. This classification signifies that the Indian Spot-billed Duck is at high risk of extinction in the wild unless proactive measures are taken to address the threats it faces.
Habitat loss and degradation are major factors contributing to the _*vulnerable* condition of the Indian Spot-billed Duck. Rapid urbanization and the encroachment of wetlands for industrial and agricultural purposes reduce the availability of its natural habitats. The destruction of these ecosystems not only deprives the duck of its breeding, feeding, and nesting grounds but also disrupts its migratory patterns.
Additionally, pollution poses a significant threat to the Indian Spot-billed Duck. Industrial effluents and agricultural runoff contaminate its wetland habitats, impacting its health and reproductive success. Toxic chemicals accumulate in the food chain, affecting the duck’s immune system and causing developmental abnormalities. Pollution can also alter the availability and quality of its food sources, further exacerbating its vulnerability.
Unsustainable hunting practices further contribute to the decline of the Indian Spot-billed Duck. In some regions, the species is hunted for its meat and feathers, leading to population depletions. Illegal hunting and poaching further jeopardize its numbers, threatening its long-term survival.

Habitat destruction poses a formidable threat to the Indian Spot-billed Duck. Wetlands, their primary abodes, are rapidly disappearing due to urbanization, industrialization, and agriculture expansion. Draining and filling of these vital ecosystems rob the ducks of their breeding, foraging, and nesting grounds, leaving them vulnerable.
2. Pollution
Pollution seeps into the aquatic habitats of the Indian Spot-billed Duck, posing severe risks to their health and survival. Industrial wastewater, fertilizers, and pesticides contaminate water sources, poisoning the ducks and disrupting their food supply. Oil spills can coat their feathers, impairing their insulation and mobility.
3. Hunting
Hunting remains a significant threat to the Indian Spot-billed Duck, despite being protected by law in many areas. Poaching for meat and feathers continues to deplete their populations. Unregulated hunting during breeding seasons disrupts their reproductive cycles, leaving fewer offspring to sustain the species.
