 of the Truckee, ami in many suitable localities to the eastward, it was a 

 rare summer resident, becoming' exceedingly numerous in autumn. Its 

 haunts durinsr the breedingf-season were much the same as those of the 

 Summer Yellow-l)inl {Dendraeca ccstlvd), but in September it was most 

 abundant in the .shrubbery along' the cafion streams.
