The Sunda teal, known scientifically as Anas gibberifrons and colloquially as Bebek cokelat or Itik benjut, is a dabbling duck of mottled brown plumage. It boasts white and green flashes on its wings, adding a touch of brilliance to its otherwise camouflaged appearance.
Both male and female Sunda teals are similarly colored, which is quite unusual compared to the sexual dimorphism seen in many duck species. The key to identifying this species lies in its lighter neck, paler face, and notably bulging forehead. Juveniles present a paler version of the adult plumage, particularly on the head.
These ducks are found in open wetlands, where they can be seen dabbling around. They have a preference for freshwater lakes and marshes, which provide the ideal conditions for their nesting and feeding habits.
The Sunda teal graces the wetlands of Indonesia with its presence. It is a bird that has adapted to the specific environmental conditions of this region.
A social and vocal species, the Sunda teal is particularly chatty at night. The males emit a soft peep, while the females are known for their loud quack, a sound that often punctuates the stillness of their freshwater habitats.
The male's soft peep and the female's loud quack are characteristic sounds of the Sunda teal, especially under the cover of darkness.
Nesting near their favored freshwater habitats, Sunda teals are ground nesters but may also use tree holes or even rabbit burrows to lay their eggs, demonstrating their adaptability.
The Sunda teal was once considered to include subspecies such as the Andaman teal and the grey teal, but it is now recognized as monotypic. It is closely related to the chestnut teal, with the female chestnut teal resembling the Sunda teal, though the latter can be distinguished by its lighter neck and paler face.
As dabbling ducks, Sunda teals feed in the water by tipping forward and grazing on underwater plants. They may also forage for food on land near the water's edge.
The Sunda teal is currently classified as Near Threatened on the IUCN Red List. Conservation efforts are important to ensure that this species does not move closer to the brink of endangerment.
