GRIFFON VULTURE. 9 
same manner as the first nest. It was not due to any carrion about the 
place (such as is frequently the case in a Neophron’s nest), but appeared 
to be caused from the dung and the natural odour of the birds. At times 
it was most nauseating. 
“ As I was making good my retreat towards the spur of the hill I met 
with a mishap which gave me rather a start. I had grown bold when I 
found the ledges of strata gave such good hand and foothold, and so did 
not take much notice of where I rested. Suddenly a piece under my foot 
gave way, and I swung round on the hand (which luckily had a good 
hold) furthest from the rock, causing my egg-bag to swing round and hit 
the rock. Luckily I somehow got a foothold and was able to reach a 
safer spot. During the time that I was rifling their nests the Griffons 
kept sailing about overhead; ever and again one bolder than the rest 
would come swooping past me, but never near enough to give me any 
apprehension. Most fortunately they did not realize what a very slight 
touch would have upset my balance when traversing the small ledges. I 
was very glad when I found myself doubling the spur, and could see that 
the ground in rear of the cliff was easy to traverse, though rough and 
broken. I made my way in rear over huge boulders with aloes and every 
sort of obstacle growing between them, the worst being prickly pears, 
which abounded. I passed a huge cave which was evidently much fre- 
quented by the Vultures as a shelter in certain winds, judging from the 
enormous amount of dung which spread like whitewash all down the face 
of the crags. 
“Upon blowing the eggs I found that four were quite fresh, or nearly 
so; the rest contained young Vultures in various states of development : 
one would have been hatched out within a week.” 
The Griffon Vulture seldom lays more than one egg, although occa- 
sionally two have been recorded, and Salvin found one egg and one young 
bird in a nest of this species in Algeria. The eggs are coarse in texture, 
and possess little or no gloss. Most eggs are white, or nearly so; but some 
show a considerable amount of marking which cannot be explained by 
any supposition of their being stained. One specimen in my collection 
is very faintly but broadly streaked and blotched on the larger end with 
very pale pinkish brown; another, one of the handsomest eggs of this 
species I ever saw, obtained by Colonel Irby at Malaga, has the colouring- 
matter very evenly distributed in spots and blotches and pale streaks 
uniformly over the entire surface; a third is washed round its centre with a 
band of reddish brown, and on the larger end is a thick irregular mass 
of rich brown; a fourth (which is figured) has the deep-brown spots 
confined to the smaller end of the egg, where they form an irregular 
zone ; whilst a fifth, which may be called a typical egg, is milky white, 
spotless or clouded here and there with staims and nest-markings. My
