681. Maryland Yellow -throat — Geothlypis 

 trichas trichas. 



Smaller than sparrow. Length 5)^ inches. 



Male — Forehead and on sides of head black; 

 throat and breast bright yellow, whitish on the 

 belly; upperparts, wings and tail olive; no wing-

Unlike most warblers, this bird frequents rather 

 open grassy or weedy places, the nest being placed 

 among the tall weeds. The plain upperparts, 

 wings and tail and the bright yellow of the throat 

 and breast are distinguishing features, while the 

 black face-patch of the male is an excellent field- 

 mark.
