About Vanellus duvaucelii (R.Lesson, 1826)
The river lapwing, scientifically named Vanellus duvaucelii (R.Lesson, 1826), measures 29 to 32 centimeters in length. It has black feathers on its crest, crown, face, and central throat, with grey-white coloration on the sides of its neck and nape. It features a grey-brown breast band, white underparts, and a black patch on its belly. Its back is brown, its rump is white, and its tail is black. This species is particularly distinctive in flight: it has black primary flight feathers, white underwings and upper wing secondaries, and brown upper wing coverts. Adult males and females have similar plumage, though males are slightly larger than females. Juvenile river lapwings have brown tips on their black head feathers, a sandier shade of brown on the back, and pale fringes on their upperpart and wing covert feathers. The call of the river lapwing is a sharp tip-tip or did-did-did.
