During' the vrinter of our residence at Carson City, several examples of 

 this northern bird were seen, but it was at all times less connnon than 

 the smaller species (C. cxculitoroides), and seemed to be confined to the shel- 

 tered ravines among tlie foot-hills of the mountains. Those observed were 

 perched on tlie sununits of the willows along a stream, patiently surveying 

 the surrounding fields and thickets, after the manner of other species of the 

 genus.
