November 2008Fondo Amigos del Buitre (FAB) studies since many years the population of Griffon Vultures at the pre-Pyrenees of Aragón (Riglos, Guara). Here we find important colonies, representing about 5% of the Spanish population in 1999 (SEO/BirdLife).

"In 2008 the population of the Griffon Vulture in this area has fallen by 21% and the number of fledged young by a 48%, compared to the 5-year period before the food crises. In 2008 62 out of each 100 nests failed. The 2007 results were quite worse. At Governmental feeding stations some 80 tons of food a month has been distributed, less than a 15% of the food demanded by the vultures."
