86 CORVID.E. 



81. Corvus corone, Linnaeus. The Carrion-Crow. 



Spanish. Gragilla. 



Not mentioned by Favier, but is included by Mr. Drake in his 

 list of the birds of Morocco ; I never met with any on the African 

 side. On the Spanish side the Black Crow is scarce, and I only 

 remember one nest, which was taken near Utrera during the 

 month of March ; another pair nested near Motril in 1893 (Mena). 



Black, with metallic gloss ; nostrils covered with bristly feathers ; base 

 of body-feathers whitish. Length 18-19 inches. 



82. Corvus cornix, Linnaeus. The Hooded or Grey Crow. 



Not recorded from the Moorish side of the Straits. Saunders 

 mentions the Hooded Crow as having been met with in 

 Andalucia ; there was one in a museum at Seville, but upon 

 inquiry it proved to be from France. I never observed any, and 

 the Grey Crow must be a very rare straggler, as Arevalo does not 

 mention it as Andalucian. 



Head, throat, wings, thighs, and tail-feathers black ; the rest of plumage 

 dull grey. Length 18-19 inches. 



83. Corvus frugilegus, Linnaeus. The Rook. 



On the Moorish side of the Straits I can find no record of the 

 occurrence of the Rook. I never met with any near Gibraltar, 

 or, indeed, further south than the Goto del Rey, in the neigh- 

 bourhood of Seville, where there were several large flocks in 

 January ; and they appear to be there regular winter visitants. 



Black, with blue gloss. 



Adults. With bare scurfy skin on forehead, lores, and throat. 



Young in first plumage have these parts feathered, and resemble young 

 Carrion-Crows, but the bases to the body-feathers are grey and the bill is 

 slender. Length 18-20 inches.
