 associated with the northwestern forests of tall firs as is that of our 

 eastern bird with the pine woods of New England. Its breeding range 

 is confined to the coniferous forests from Prince William Sound and 

 the upper Yukon in Alaska south to Washington and east to south- 

 western Alberta and western Montana, but it is better known as a 

 migrant through the Eocky Mountain region in general and as a 

 winter visitant in California.
