PASSERINE BIRDS OF NEW YORK 247 



and auriculars jet-black veiled slightly with pale buff. Broad submalar 

 stripes joining at angle of the chin, and superciliary lines white. Outer half 

 of median and greater coverts bright lemon-yellow forming an almost con- 

 tinuous wing patch, lesser coverts plumbeous gray, edged with olive-green. 



4. FIRST NUPTIAL PLUMAGE acquired by wear, through which 

 the buff edgings of the black areas, the olive edgings of the 

 back and the yellow edgings below are almost completely lost, 

 the plumage becoming clear gray, white, yellow and black. 



5. ADULT WINTER PLUMAGE acquired by a complete post- 

 nuptial moult in July. Practically indistinguishable from the 

 young bird, the veiling usually less marked or absent, and black 

 occupying the whole interramal space which is white in the first 

 winter dress. 



6. ADULT NUPTIAL PLUMAGE acquired by wear as in the 

 young bird. 



Female. In Juvenal plumage the sexes are alike. In first 

 winter and other plumages olive-gray, dusky on the lores and 

 auriculars, replaces the black areas of the male, and olive-yellow 

 marks the crown. Above, the plumage is greenish ; the sub- 

 malar stripes are grayish.

 plumage and wing coverts, but not the rest of the wings nor 

 the tail. Young and old becqme practically indistinguishable in 

 many cases.
