Flight of whistling ducks widowers Dendrocygna vid
Author 'Francis-Sisco' (Id 230943 ) : The Dendrocygne widower lives in the tropical areas of south America, Africa south of the Sahara, Madagascar and the Comoros.
The dendrocygne widower has a powerful flight performance thanks to its large wings. In flight, it appears completely dark, with the contrast of the white of the head, and the distinctive silhouette of the wigeons, the long neck stretched out and the legs considerably projected to the rear of the short tail. The beating of the wings are relatively deep. Lien : Https://fr.wikipedia.org/wiki/Dendrocygne_veuf
