500 Vultures

Again, a visit to the rubbish dump of Villarcayo (Burgos) has supposed the observation of nearly 500 Griffon Vulture (Gyps fulvus), one of the concentrations greater than I have seen, practically all in flight on the place. Other observed species have been Red Kite (Milvus milvus) (35), Carrion Crow (Corvus corone) and Common Raven (Corvus corax) of which peculiarly there were very few individuals (15).
