sharply ascending scale, the last three in a 

 sharply descending scale. The song is en- 

 tirely different from that of any other western 

 warbler and as it comes floating down from

 bird music. 



The nest of the hermit warbler is placed in 

 all sorts of locations from small trees along 

 mountain streams to high conifers in the 

 mountains.
