Corvus dominicensis Cory, Auk, 1886, p. 228. (Proposed as new from the 

 Dominican Republic.) 



Resident; locally common. 



We have termed this bird the white-necked crow because though 

 in life it appears wholly black when in the hand it is found that the 

 feathers of the hind neck at the base are pure white, this color being 

 entirely concealed by the black overlying feather tips. The present 

 species is distinctly larger than the other crow of the island and 

 utters higher pitched notes that are rather like those of the ravens
