Dendrocygnini

The tribe Dendrocygnini, commonly known as whistling ducks, are a distinct group of eight species within the Anatidae family. These long-legged, long-necked waterfowl are characterized by their sibilant calls and sociable, though sometimes aggressive, behavior. Both sexes typically share similar plumage and engage in mutual preening.1

Whistling ducks are capable of slow wingbeats in flight, often with their legs trailing. They are also known to perch in trees or on posts and walk with an upright stance. While some species nest in hollow trees, ground nesting is more common. In many species, males participate in nest building and raising young, and may also share incubation duties.1

Examples of whistling ducks include the fulvous tree duck (Dendrocygna bicolor), found in disparate populations across the Americas, India, and Africa, and the West Indian whistling-duck (Dendrocygna arborea), a secretive species native to the West Indies that is considered endangered. The black-bellied whistling-duck (Dendrocygna autumnalis) is another species, known for perching in trees and being active in the evening or early morning. It is important to note that whistling ducks are not true ducks but are more closely related to geese and swans.1234
