470 ORNITHOLOGICAL SKETCHES 
with vultures. Every second fresh arrivals came plunging 
down from above, and I quickly began to number them. Ina 
few minutes there were seventy-five Griffon Vultures and one 
Egyptian Vulture on that one spot; but almost before I had 
finished counting, the birds left the place one after another 
and flapped heavily about. Of the sheep there remained 
nothing but some spots of blood, a little wool, and its bones, 
which lay scattered in all directions. 
This feast of the vultures was a singular and interesting

with my rifle, and afterwards the vultures gradually flew 
away in yarious directions. On my way back I saw some

Throughout Spain the Griffon Vulture is more or less a 
perfectly cormmon bird, I might even say a characteristic 
creature of this wild, stony, thinly populated country. The 
observer will find no difficulty in seeing it at any hour of the 
day, though generally at a great distance. At the nest, how- 
ever, it is not easy to study it closely, for its dwelling is
