towns or liirgei* settlements, however, a large proportion of t,be individuals; 

 of this species have abandoned such nesting-places as those described above, 

 and resorted to the buildings, where "odd nooks and crannies" afforded 

 superior attractions. 



Although chiefly a bird of the lower valleys, this species was sometimes 

 found in the lower canons of the mountains, it being common in Buena 

 Vista Canon, in the West Humboldt range, in September, having apparently 

 nested among the ruined adobe houses of the deserted town. In City 

 Creek Canon, near Salt Lake City, several nests were found at an altitude 

 of about 1,800 feet above the level of the mesa, or at the lower limit to the 

 breeding- ranee of C. cassiui, a sinn^le nest of ^\llil■h was found on a tree 

 adjoining one in whicli was a nest of the present bird. In Parley's Park it 

 was likewise found, but in small numbers, and only on the floor o^ thu 

 park, the C. cassini inhabiting the upper portion of the streams.
