buff tipped. Below grayish Avhite with distinct dusky vermiculatioiis except on 

 the chin, abdomen and crissum. Tail black, the three outer rectrices with 

 much white. Lores grayish. Bar through eye dusky. 



4. First Nuptial Plumage acquired by a partial prenuptial 

 moult in March which inv^olves the anterior part of the head, 

 chin and throat. A whiter chin and black lores are acquired, 

 young and old becoming practically indistinguishable. A good 

 deal of the vermiculation is lost by wear of the feather edges. 



5. Adult Winter Plumage acquired by a complete post- 

 nuptial moult. Differs from first winter in having a white wing 

 band on the greater co\erts, the tertiaries and secondaries with 

 white edgings, the wings and tail jet-black, including all the 

 coverts. The back is graj^er without the bro\vnish tint of the 

 young bird. 



6. Adult Nuptial Plumage acquired apparently by a partial 

 prenuptial moult as in the young bird. 



Female. — The plumages and moults correspond to those of 

 the male. Usually browner, especially the wings and tail and

 dusky subterminal bands on each feather. Bill and feet dusky becoming black. 



3. First Winter Plumage acquired by a partial postju venal 

 moult in September and October, which involves the body 

 plumage, tertiaries, wing coverts and tail, but not the rest of the 

 wings. 



Similar to previous plumage but grayer above and the vermiculations absent or very
