not much like the eastern fish crow, appears to possess its peculiar habits. In all essential 
features it is like the common Corvus americanus ; so much so, indeed, that but for the slight «if- 
ference in size it would be difficult to tell skins of the two apart. According to Drs. Cooper end 
Suckley, they are maritime, feeding on the sea beach at low tide, and coming about the setile- 
ments with considerable familiarity, being much less shy and suspicious than the common crow. 
The note, too, is said to be a little different. 
The species is readily distinguished from the eastern fish crow by the larger size, the absence 
of green gloss on the belly ; the tarsi longer than the middle toe and claw instead of shorter, 
and the second quill being generally shorter than the sixth instead of longer. It is so much 
like the Corvus americanus as to be only distinguishable by its inferior size and habits. Indeed, 
it is almost a question whether it be more than a dwarfed race of the other species. 
Crows from California and one from Vancouver (10303) agree, by their larger size, with the 
eastern Corvus americanus, and may thus be distinguished from the C. cawrinus,
