CORVUS CORONE. 127 
which is carried from the town and thrown on the sea-shore. 
They are exceedingly tame to the natives, being viewed with 
superstitious awe by the Moors, but are wide awake to the 
European, especially if he carries a gun, and if once fired at 
will not give a second chance. The only way to be sure of 
getting them is at the nest, which is constructed of sticks, 
neatly lined with grass and small roots, and is built in clefts 
of rocks, on trees and in low bushes ; one nest which I saw 
was fixed in the crook or angle formed by a dead flowering 
stalk of the aloe, which had fallen across another stalk in full 
flower. 
The eggs are usually laid about the 2()th of April, and vary 
in number from five to seven, and, like those of others of the 
Crow tribe, difler much in the markings. Favier in his MS. 
says of this E-aven, under the head of C. corax, " This species

and heart of the Hoopoe. The Raven is the only species of 
Crow found in the neighbourhood of Tangier, and is very

indeed, further south than the Coto del Rey, in the neighbour- 
hood of Seville, where there were several large flocks in 
January ; and it appears to be there a regular winter visitant. 
On the Moorish side of the Straits I can find no record of 
its occurrence. 
178. CoRvus CORONE, Liuu. The Carrion-Crow. 
Not mentioned by Favier, but is included by Mr. Drake in 
his list of the birds of Morocco ; I never met with it on the 
African side. On the Spanish side it is scarce, and I only
