ORNITHOLOGICAL EXPLORATIONS. 239 



Being acquainted with Dybowski's statement respecting the crow- 

 like voice of the Siberian raven, I paid special attention to the sounds 

 uttered by our island form. I can most emphatically state that the latter 

 lias a voice which in no respect is like that of a crow {Corvus comix), 

 and the common notes "kroh'' and "korr" are in fact almost identical 

 with that of the Norwegian C. corax, while the bell-like, sonorous " klong, 

 klong" is higher and a little less sounding. It has, however, another 

 very peculiar note, which I have never heard before. It often happened 

 on Copper Island that, when engaged in climbing high up on the steep 

 mountain peaks, I was startled by a sonorous and distinctly articulated 

 "halo, halo!" so like the voice of a human being that I repeatedly 

 looked around to discover the supposed Aleut before raising my eyes 

 to the skies, where the black scavenger amused himself by hallooing to 

 a neighbor on the other side of the valley, who would then answer with 

 a similar "halo!" It was only distinguishable from the human voice 

 by its somewhat more metallic sound. 



I need hardly add that the raven here, as in most places where he 

 has been for some time in contact with man, is extremely shy and diffi- 

 cult to get at within shot range.

The specimens of the Carrion Crow collected by me at Petropaulski 

 agree in every respect with skins from Japan. The latter has been 

 stated to be the same as the European C. corone, but a careful com- 

 parison has led me to a different conclusion. While agreeing with the 

 European bird in size the color is quite different. In the true corone 

 the gloss all over is most decidedly purplish, while in the Kamtschat- 

 kan and Japanese specimens before me the luster is equally decidedly 

 greenish. In fact, the latter come, in this respect, nearer to the big.
