like the sides of the neck ; under surface of body dull white, with 

 a tinge of pale yellow ; sides of the body with faint dusky streaks ; 

 thighs dusky ; under tail-coverts white, with scarcely any tinge of 

 yellow; under wing-coverts and axillaries white, mottled with 

 dusky bases along the edge of the wing ; quills dusky below, whitish 

 along the edge of the inner wob. Total length 4-7 inches, culmen 

 0-5, wing 2-4, tail 1-7, tarsus 0-55. 



1 ouHff in autumn plumage. General colour above dull olive-brown, 

 a little clearer greyish on the head ; wing-bar obscured by a tinge 

 of olive ; quills margined with olive ; entire under surface of body 

 pale yellow, a little whiter on the lower abdomen and under tail- 

 coverts ; lower mandible pale. 



From the above it will be seen that the winter plumage of the 

 young birds more resembles that of the adult female. The males 

 can, however, always be told from the females, even in the winter 

 dress, by the more distinct stripes on the sides of the body, and 

 generally by a tinge of blue on the head. 



Hab. Eastern North America to the Eocky Mountains in the 

 latitude of Colorado, and to the Lower Missouri ; rare in the 

 Atlantic States, but occurs in New England ; Canada West {Coues). 

 Cuba. Extends in winter throughout Central America from Mexico 

 to Panama, and into Colombia, Ecuador, Peru, Bolivia ; ? Brazil.
