Mr. Wilson says that immature specimens have the whole plumage of a more rusty shade, 

 and the primaries light ochreous. 



This Raven is known only from the island of Hawaii, where, according to Mr. Wilson, it is 

 confined to elevations of 1100 to 6000 feet in the districts of Kona and Kau. In the former 

 it was met with, not uncommonly, both by Palmer and Wilson. The former sent me 

 1G specimens. The cry is apparently truly corvine, for Peale compared it with that of the 

 North-American Fish-Crow (Corvus oaaifragus), and Palmer with that of the English Rook. 



In November Palmer saw these Crows collecting nesting-material, and in June 

 Mr. Wilson states that the broods had already left the nest. The eggs are unknown; the 

 nest is said to be a loose structure of dead twigs and placed on trees. 



The principal food consists of the fruit and flowers of the Ie (Freycinetia arborea), but 

 Palmer says that it also eats meat, insects, and various fruits. 



This Crow is not shy, and can easily be shot, when attracted by an imitation of its cry.
