GYPS HISPANIOLENSIS. 29 
A few days after, on the 26tli of February, I again 
examined the nest, only to find it lined with wool and a few 
rushes. Muster-day at Gibraltar, on the 28th, compelled our 
return to the Rock ; so I engaged a man to take the nest and 
bring the egg to Gibraltar, which he never did, probably not 
liking the journey through the swampy jungle. The following 
year this nest was not used by any birds ; but in 1874 a pair 
of Eagles (apparently Aqv.ila adalberti) took possession, re- 
building and lining it with fresh green boughs. This was early 
in March ; and with persistent bad luck, on our return there 
in April, my friend found nothing in the nest, although the 
Eagles were about. I imagine that they had been robbed of 
their eggs, or else had deserted it owing to too frequent 
examination. 
The Black Vulture is said to nest near Utrera ; but upon 
inquiry I could not ascertain such to be the case ; they 
appear to go further north to breed, as Lord Lilford found 
them nesting towards Madrid, and in one season received no 
less than some seventy eggs. More solitary in habits than 
the Griffon, and unlike that Vulture, they build in trees and 
not in colonies — laying only one egg, about the beginning of 
April. 
This Vulture is to be recognized when on the wing, within 
a short distance, by its dark appearance. The immature 
birds are very dark-coloiu-ed, becoming lighter with age, till 
they attain the adult plumage. The bare skin about the head 
and neck is of a pale bluish colour.

'' This Vulture occurs commonly near Tangier, both as a 
resident and on passage, and is often seen feeding in company 
with the Neophron on the same carcass. ^^ — Favier. 
I did not see many Griffon Vultures in Morocco, but 
there were a few pair about Jebel Moosa in April. Near 
Gibraltar they are very plentiful, nesting in colonies, not 
exceeding thirty-five pairs, in holes or, rather, small caves in
