wings and tail blacker and the edgings grayer rather than 

 greener as in the young bird ; a few chestnut feathers sometimes 

 appear on the throat and the crown. 



6. Adult Nuptial Plumage acquired by a partial prenuptial 

 moult as in the young bird. 



Female. — The plumages and moults correspond to those of 

 the male. Distinguishable first in first winter plumage, which is 

 a clearer green \\'ithout the crown streaks of the male, the black 

 spots on the back duller and usually even a trace of chestnut is 

 lacking on the flanks. The first nuptial plumage acquired by a 

 limited moult approaches in pattern and color that of the male, 

 but is much duller and the chestnut limited. The adult winter 

 plumage is similar to the first winter, but whiter below, with a 

 a wash of chestnut on the flanks and with crown streaks and the 

 dorsal spots better defined, resembling closely the male first 

 winter dress, although usually rather duller. The adult nuptial 

 plumage is practically indistinguishable from the first nuptial, the 

 older birds with richer colors, but the chestnut is at most merely 

 a crown patch, a pectoral band and a wash on the sides.

3. First Winter Plumage acquired by a partial postjuvenal 

 moult, in July and August in eastern Canada, which involves 

 the body plumage and the wing coverts, but not the rest of the 

 wings and the tail. 



Similar to previous plumage but unspotted. Above, including sides of head, olive- 

 green, olive-gray on tail-coverts, rather obscurely streaked, chiefly on the back, 

 with black. The wing coverts clove-brown edged with olive-green and tipped 

 with white, yellow-tinged. Below, very pale canary-yellow, white on abdomen 

 and crissum with a few obscure grayish streaks on the throat and sides. A
