3. HEIMINTHOPHILA. 



241 



brown, paler beneath; feet brown, tinged with blue; iris hazel" 

 {Auduhon). Total length 4-4 inches, culmen U"45, wing 2'55, 

 tail 1-75, tarsus 0'65. 



Adult female. Like the male, but the ashy of the head less pui'e 

 and clear, and the underparts more or less tinged with greenish 

 yellow. (Coues.) 



The male in winter plumage is much more uniformly olive above 

 than in summer, the upper surface being entirely yellowish oHve, 

 including the head, which is only a little more dusky than the 

 back ; the eyebrow, sides of face, and throat are yellow instead of 

 white ; centre of breast and abdomen, as well as the under tail- 

 coverts, white ; the ilanks and sides of tlie body olive-yeUow. 



Young birds are described by Dr. Coues as being similar in 

 plumage to the above, and the changes appear to resemble those of 

 the common Plujlloscopi of Europe, which are always yellower in 

 autumn than in summer ; but, unlike the European birds, this Hel- 

 mhithojildla appears to regain its full spring plumage by the wearing 

 away of the olive tips to the grey crown, rather than by a complete 

 spring moult — at least I can find no evidence of the latter in the 

 series of specimens examined. 



The adult female in winter differs from the male of the same time 

 of year only in being duUer in colour. 



Hah. Chiefly Eastern North America, but west to the Upper 

 Missouri region and in Colorado to the Eocky Mountains ; common, 

 especially in tke Mississippi valley, but less so in the Atlantic 

 States ; migratory ; breeds in New England and the northern tier 

 of States, and thence to high latitudes in British America {Coues). 

 Winters throughout Central America, and as far south as Co- 

 lombia and Venezuela.
