162 PASSERES : Perching Birds 



RAVEN 



(486. Corvus corax sinuatus) 22-25 in. 



Entirely black, glossed with purplish. A huge crow in appear- 

 ance, but with a hoarse, guttural croak instead of the familiar 

 "caw, caw" of the crow. 



Any sort of animal matter, whether carrion, shell-fish, insects, 

 or the eggs or young of other birds, is the Raven's food. 



A wily, sagacious bird, endowed by Nature to persist in spite 

 of universal persecution. 



WHITE-NECKED RAVEN 



(487. Corvus cryptoleucus) 19-21 in. 



A small Raven that might easily be mistaken for a large Crow. 

 Its voice, however, is characteristic, being neither Raven nor 

 Crow. 



Neck feathers pure white at base visible only when they 

 are ruffled. 



Food habits appear identical with others of its genus, except 

 as affected by different habitat. 



WESTERN CROW 



(488b. Corvus brachyrhynchos hesperis) 18 in. 



Entirely black, glossy above, with purplish reflections. 



A "wise" bird like the rest of his clan, his sagacity fits him to 

 survive where other species of smaller intelligence must in time 

 be lost. His "caw, caw" advertises his presence at a safe 

 height in the air.
