The Lesser Whistling Duck, also known as Dendrocygna javanica, is a fascinating bird species that can mesmerize anyone with its unique characteristics and captivating presence. Found throughout Asia, these ducks can also be spotted in the diverse and picturesque landscapes of Nepal. In this article, we will delve deeper into the fascinating details of this bird and explore its distinctive features and habitat in Nepal.
Distinctive Features of the Lesser Whistling Duck
The Lesser Whistling Duck is a medium-sized waterfowl, measuring around 40-45 cm in length with a wingspan of 65-75 cm. One of the most striking features of this bird is its reddish-brown plumage with darker streaks on its back. The chest is paler, while the neck and head are light grayish-brown. A black ring encircles the eyes, giving it an enigmatic appearance.
While in flight, these ducks emit a distinctive high-pitched whistling sound – a peculiar characteristic that earned them their name. This melodious whistle is unique and can be easily distinguished from other waterfowl sounds.
Habitat and Distribution in Nepal
The Lesser Whistling Duck prefers freshwater wetlands such as marshes, swamps, lakes, and ponds surrounded by vegetation and trees. They can also be found foraging on rice paddies and agricultural fields, making their presence noticeable across different landscapes.
In Nepal, their preferred habitats are lowland areas such as the Terai belt and riverine forests or wetlands along rivers like the Rapti and Narayani. During migration seasons, they make brief appearances at higher altitudes but predominantly reside in lowland wetlands.
Behavior and Diet
Lesser Whistling Ducks are mainly nocturnal, spending daytime hours resting on trees or floating on the water. As dusk sets in, they become more active and start searching for their preferred meals. Their diet primarily consists of aquatic plants, seeds, insects, small fish, and crustaceans. They also glean rice fields for leftover grains.
Breeding and Conservation
Lesser Whistling Ducks typically breed during the rainy season, when water levels are high and vegetation is plentiful. Nests are built close to the ground or on tree branches near water bodies. The female incubates 8-12 creamy-white eggs while the male fiercely guards the nest.
Though not globally threatened, Lesser Whistling Ducks face risks such as habitat loss due to human activities like deforestation and wetland drainage. In Nepal, efforts are underway to conserve wetlands and their inhabitants to ensure a secure future for these enchanting birds.
In conclusion, the Lesser Whistling Duck is a captivating species whose presence adds beauty and charm to the diverse landscapes of Nepal. Efforts to conserve their habitat will not only help protect these birds but also contribute towards preserving the rich biodiversity of Nepal's natural world.
