Gyps

Gyps is a genus of Old World vultures that was proposed by Marie Jules César Savigny in 1809. Gyps vultures have a slim head, a long slender neck with downy feathers, and a ruff around the neck formed by long buoyant feathers. The crown of their big beaks is a little compressed, and their big dark nostrils are set transverse to the beak. They have six or seven wing feathers, of which the first is the shortest and the fourth the longest.[1] Gyps comprises the following species:
