140 YELLOW-RUMP WARBLER. 



belly and vent white, the latter spotted with black; bill and legs 

 black. This is the spring and summer dress of the male; that of 

 the female of the same seasons differs but little, chiefly in the co- 

 lors being less vivid and not so strongly marked with a tincture 

 of brownish on the back. 



In the month of October the slate color has changed to a 

 brownish olive, the streaks of black are also considerably brown; 

 and the white is stained with the same color; the tail coverts, how- 

 ever, still retain their slaty hue, the yellow on the crown, and sides 

 of the breast becomes nearly obliterated. Their only note is a 

 kind of chip, occasionally repeated. Their motions are quick, and 

 one can scarcely ever observe them at rest. 



Tho the form of the bill of this bird obliges me to arrange 

 him with the Warblers; yet in his food and all his motions he is 

 decisively a Flycatcher. 



On again recurring to the descriptions in Pennant of the "Yel- 

 low-rump WarbW* "Golden-crowned W.'^t and "Belted W."t 

 I am persuaded that the whole three have been drawn from the 

 present species.
