10 BRITISH BIRDS, 
friend Mr. Howard Saunders tells me that in Southern Spain there is a 
colony of Griffon Vultures whose eggs are always more or less spotted 
and streaked. Griffon Vultures’ eggs vary from 3°85 to 3’5 inches in length, 
and from 2°9 to 2°7 inches in breadth. Eggs of the Black Vulture (Vul- 
tur cinereus), although, as a rule, richly marked, sometimes very closely 
resemble those of the Griffon Vulture. It is then impossible to separate 
the eggs of the two species with certainty,—although in the fie/d confusion 
can never arise; for the Black Vulture invariably nests in trees, and the 
Griffon just as invariably on rocks. 
The Griffon Vulture is a buffish-brown bird with nearly black wings 
and tail, and with the head and neck covered with white down. The bill 
is pale brown and the legs lead-colour ; not vice versdé, as is erroneously 
given in Dresser’s ‘ Birds of Europe.’ 
The young birds, when newly hatched, are covered with white down.
