BLACK-AND-GRAY BIRDS. 



HOODED CROW.— Plate S. Lengtli, 19 inches. 

 Head, throat, wings, and tail glossy black, but 

 readily distinguished from all other members of the 

 Crow family by its ash-gray back and under parts. 

 Resident. 



Eggs. — 4-5, bluish-green, spotted and blotched 

 with olive -brown, of the same size as those of 

 the Carrion Crow, but sometimes rather longer 

 (plate 121). 



Nest. — Like that of the Carrion Crow, and placed 

 on rocks inland or by the sea, or in tall trees. 



Distribution. — Common in Ireland and Scotland ; 

 less common in the Isle of Man ; rare in Wales. 

 Large immigration from the Continent on our east 

 coasts in autumn. 



This bird is held to be a variety of the Carrion 

 Crow, and its form, flight, cry, feeding, and nesting 

 habits are the same. The areas of distribution of the 

 two species are largely complementary, interbreeding 

 taking place where they overlap. 



JACKDAW — 14 inches ; najje alone gray. 



BLACK TERN.— Form, like Common Tern (plate 

 114), but tail only slightly forked. Length, 10 inches. 

 Upper parts slate-gray ; tail paler, short for a Tern, 

 and not deeply forked ; head, neck, and under parts
