The male Black-throated Blue Warbler can be identified at sight, 

 but his obscurely colored mate has been the cause of many a field 

 student's neekache. When flitting about with other Warblers it is 

 difficult to observe any positive character by which to distinguish her; 

 but the white spot at the base of the primaries is an unmistakable 

 mark, if one can see it clearly. 



When nesting, the birds seem to require woods with rather heavy 

 undergrowth. Their call-note is a sharp, recognizable chijD. The 

 song of the male is generally written zivee-zivee-zwee, but both call- 

 notes and song are subject to variation.
