BIRDS OF KORTH AND MIDDLE AMERICA. 571 



Yoimg male, nestling jplimiage. — Above uniform brownish gra}^ 

 (deep drab-gray), the pileum divided long'itudinally by a broad median 

 stripe of grayish white; sides of head (including a broad superciliary 

 stripe) and entire under parts white; a narrow postocular stripe of deep 

 drab-gray; wings as in adults, but edgings greenish rather than bluish. 



[Autumnal and winter adults do not differ from spring and summer 

 specimens except in being more highly colored. This is more evident 

 in females, in which the superciliary stripe and under parts are often 

 entirely pale sulphur or primrose yellow. 1 have not seen specimens 

 which I am able to identify as 3"oung, of either sex, in first autumn or 

 winter; possibly some of the yellower supposed adult females are in 

 reality immature birds.] 



Eastern United States, chiefly west of the AUeghenies; breeding 

 northward to eastern Nebraska (Omaha), Minnesota, Wisconsin, Michi- 

 gan (as far as Mackinac Island), Ontario (Drummondville, etc.), western 

 and central New York (Niagara, Oneida, and Monroe counties), east- 

 ward to eastern Mar3dand (Baltimore County) and western Virginia 

 (Natural Bridge), southward to Tennessee, Louisiana (Franklin and 

 St. Tammany parishes), etc.; casually or irregularly northward to 

 Connecticut (Suflield; Seymour), Rhode Island (Providence; Paw- 

 tucket), Long Island (Crow Hill), and New Jersey (Morris County); 

 west regularly to edge of the Great Plains, occasionally to Rocky 

 Mountains (Denver, Colorado; Rio Mimbres, New Mexico). In winter

 America, and western South America (chiefly east of the Andes) to 

 central Peru and Bolivia (Naipiri).
