428 ORNITBOLOGY. 



These same individuals, in the case of non-resident sjiecies, during their 

 autumnal migration, probably follow the bases of the mountain ranges 

 directly southward, instead of returning by the devious route by which 

 they reached the western portions of the country. The occasional cap- 

 ture of such species as those named above, and the more accidental occur- 

 rence of others, as Edopistes migratoria (see pp. 355, 380, 385, and 596), at 

 localities in the Western Region, may thus be accounted for.

This interesting little Warbler Avas first observed among the cedar and 

 pifiwn groves on the eastern slope of the Ruby Mountains. It was not met 

 with west of this locality, but eastward it occurred on all those ranges 

 liaving a similar or equally extensive growth. At the first-named locality 

 it was rather common in July and August, and Avas found in the same 

 groA'cs with the Black-throated Gray Warbler (Dendrceca nigresccns) and 

 the Lead-colored Vireo (Lanivireo plumhcus). On the Wahsatch and Uintah 

 Mountains it was more abundant, being particularly plentiful among the 

 scrub-oaks on the foot-hills near Salt Lake City. They lived entirely 

 among the bushes, which there were so dense that the birds were difficult to 

 obtain, even when shot. The usual note of this species is a soft pit, very 

 different from the sharp cMp of //. cdata, Avhile its song is so exceedingly 

 similar to that of the Summer Yellow-bird (Dendrosca cestiva) that we often 

 found it difficult to distinguish them.
