 on the nimp and upper tail-coverts ; lesser -wing-coverts like the 

 back : median and greater coverts dusky ashy brown, externally 

 washed ■with olive -greenish ; bastard-wing dusky brown ; primary- 

 coverts and quills dusky, edged with dark olive, more ashy on the 

 primaries, the first primary whitish along the outer margin ; tail- 

 feathers light ashy brown, edged with olive, the outer ones fringed 

 with white along the tip of the inner web ; head greyer than the 

 back, ashj"^ washed with olive-green ; lores black, extending below 

 the eye, and surmounted by a broad streak of white from the base 

 of the bill to above the eye ; eyelid white ; ear-coverts slaty grey, 

 washed with olive ; cheeks, throat, and entire breast bright yellow ; 

 entire abdomen, thighs, and under tail-coverts white ; sides of 

 breast washed with olive-green ; flanks pale brown ; asillaries and 

 under wing-coverts pale lemon-yellovs^ ; quills dusky below, ashy 

 white along the inner web : " bill black, the base of the lower man- 

 dible blue ; feet greyish blue ; iris hazel " (Audubon). Total length 

 7*5 inches, culmen 0"65, wing 3'15, tail 3*2, tarsus 1-05. 



Winter ijlumaiie. Seems to differ from the summer dress only in 

 having the head and ear-coverts as distinctly olive as the back, 

 without any ashy grey ; the flanks and under tail-coverts more 

 distinctly washed with pale brown, as well as the thighs. 



" There is very little difference with sex, age, or season in this bird, 

 excepting in the purity and intensity of the tints. The yellow of 

 the breast is sometimes heightened to orange, or may show golden 

 as usual, with stains of intense orange here and there. Immature 

 specimens have the under mandible light plumbeous or plumbeous 

 white. In very young birds the yellow may appear as slashing in 

 ihe white, and the peculiar markings of the sides of the head are 

 defective." {Coues.)
