WOOD WARBLERS 



dent of the Pacific Coast. Wintering through 

 Mexico to Central America. 



The bhick-throated gray warbler is abun- 

 dant throughout its range from sea level to 

 high mountains in both coniferous timber 

 and mixed woods. It keeps more to the upper 

 branches than do most of the warblers, es- 

 pecially in bright weather but comes down 

 into the lower branches and undergrowth in 

 misty or cloudy weather. It has striking 

 black and white, lengthwise streaked plumage 

 making it easily recognized among all our 

 western warblers, except Townsend's, which it 

 resembles in general appearance at a distance, 

 but which, when seen closely will not be con- 

 fused with it. The song of the black- 

 throated gray warbler is an indistinct medley 

 of notes resembling that of both the Town- 

 send and hermit, except in the ending, which 

 has a zee, zee quality that is distinctive and 

 may be recognized as far as it is heard. The 

 nest is placed in some conifer from twenty to 

 fifty feet from the ground.
