Mr. Aiken communicates the following : 



" It seems to me not a little singular that I should have been the first 



to detect the presence of this bird in Colorado ; for it outnumbers all the 



other Corvi in certain localities. It had previously been considered a bird 



of the southeast, and was supposed to be confined mainly to the Staked 



Plains of Texas ; but I now know it to be common along the eastern base of 



the Rocky Mountains, throughout the entire extent of Colorado, and it even 



winters as far north as Cheyenne. It has also been found at Tucson, Ariz., 



by Captain Bendire, who includes it among the resident birds of that 



locality, so that it has quite an extended range. I first saw them in October, 



1871, about twenty-five miles south of Cheyenne, on the line of the Denver 



Pacific Railroad, where a large flock was hovering over the plain. In the 



city of Denver, I have often seen them searching for food in the less 



frequented streets, and about one hundred miles farther south, on the 



F< mtaine Qui Bouille, I have seen immense numbers. At the latter place, 



a flock of probably one thousand individuals was resident during the 



winter of 1S71-72. Although so abundant in winter, very few are to 



Le seen in summer; the greater number either pass to the northward or
