This .sprij^-htly Warbler was not .scyu at Sacramento, liiit in the valhy 

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

 rare summer resident, becoming exceedingly numerous in autumn. Its 

 haunts during- the breeding-season were much the same as those of the 

 8unnner Yellow-bird {Bendnicca astiva), but in September it was most 

 abundant in the .shrubbery along the canon streams.
