Griffon Vultures travel long distances in search of food and the birds seen in the skies over Trujillo are mainly from the colonies in Monfragüe National Park, about 50 kilometres away. With their broad wings they use termals in the sky to soar to great height and then gliding a long way without needing to flap their wings. They can also be seen on the ground on the plains near Trujillo where they may be attracted by carrion. An animal carcase can bring in sometimes as many as fifty vultures or more. At such a gathering there will be a lot of noisy squabbling between individuals. Griffon Vultures are resident species.
