5. Adult Winter Plumage acquired by a complete post- 

 nuptial moult in July. Similar to the first winter dress but the 

 streaking below broader, and the wings and tail blacker with 

 grayer edgings ; but none of these differences are constant, and 

 a dull adult may easily be mistaken for a high-colored young 

 bird. Spotting on the back is more extensive and a solid patch 

 of black may be* assumed. 



6. Adult Nuptial Plumage acquired by a partial prenuptial 

 moult which involves the same areas as in the young bird with 

 similar results. Black edging on the nape and a more solid 

 black patch on the back may be acquired, with less of the 

 greenish edgings that are common to }-oung birds. The wings 

 and tail being blacker, show less wear. 



Female. — The plumages and moults of the female correspond 

 to tho.se of the male, the prenuptial moult always more restricted 

 as is regularly the case with females of all species. The juvenal 

 plumage is the same as that of the male, the wings and tail and 

 their edgings duller. The first winter plumage is browner above, 

 especially on the pileum than that of the male, the yellow rather 

 paler below and the streaking scanty and obscure. The first 

 nuptial plumage resembles the previous dress but the throat is 

 distinctly streaked with black, the auriculars are blackish instead 

 of gray, tne orbital ring whiter and posterior part of the super- 

 ciliary line white. The adult winter plumage differs but slightly 

 from first winter, the wing edgings grayer and the streaks 

 broader, but duller than the male first winter. The adult nuptial 

 plumage has the pileum browner than in nuptial male plumage, 

 the streaks fewer and the black of the back merely streaks, 

 never solid.

1. Natal Down. No specimen seen. 



2. Juvenal Plumage acquired by a complete postnatal moult.

 edged largely with bice-green, the primaries with bluish cinereous gray, the 

 tertiaries with grayish white, the coverts with drab, two wing bands white. 

 Below, grayish white, faintly tinged with primrose-yellow. Bill and feet pink-
