Wandering Whistling Duck

The Wandering Whistling Duck, known scientifically as Dendrocygna arcuata, is a distinctive species of whistling duck. With long necks and legs, they present a unique silhouette that is somewhat intermediate between a goose and a duck. Their plumage is primarily dark brown, adorned with black spotting on the breast, and they possess a strong head and neck with a darker crown and hindneck. These birds measure between 54 to 60 centimeters in height and weigh an average of 750 grams.

Identification Tips

To identify the Wandering Whistling Duck, look for their characteristic long neck and legs, as well as the dark crown and hindneck that contrast with the rest of the body. The black spotting on the breast is also a key feature. In flight, listen for the whistling noise their wings produce, which is a hallmark of this species.
