4. FIRST NUPTIAL PLUMAGE acquired by wear which pro- 

 duces little obvious change. 



5. ADULT WINTER PLUMAGE acquired by a complete post- 

 nuptial moult in August. Practically indistinguishable from 

 the first winter ; the wings and tail perhaps averaging blacker 

 and with grayer edgings. 



6. ADULT NUPTIAL PLUMAGE acquired by wear as in the 

 young bird.

 tail.

2. JUVENAL PLUMAGE acquired by a complete postnatal moult. 



Above, cinnamon-brown mottled or streaked with dull clove-brown. Wings and 

 tail deep cinnamon-rufous or russet; the tail with "watered" barring; the 

 wing edgings richer rufous ; coverts dusky terminally and tipped with pale 

 buff forming two wing bands ; the tertiaries narrowly edged with pale buff ; 

 the alulae with white. Below, dull white, a buffy wash on the throat, sides 

 and crissum, streaked broadly except on the chin and mid-abdomen with dull 

 black. Bill and feet dull pinkish buff, the former becoming slaty, the latter 

 dusky. 



3. FIRST WINTER PLUMAGE acquired by a partial postju venal 

 moult, beginning towards the end of July, which involves the 

 body plumage, usually most of the wing coverts and not the 

 rest of the wings nor the tail, young and old becoming practi- 

 cally indistinguishable. 



Similar to previous plumage but unstreaked above Above, rich deep cinnamon- 

 rufous ; white below, streaked with black and washed on throat, sides and 

 i crissum with ochraceous buff; the wing coverts cinnamon-rufous, the wing. 

 bands buffy white. 



4. FIRST NUPTIAL PLUMAGE acquired by wear which is 

 marked, although, until late in the season, the colors fade little 

 except the buff below, the streakings coming out clear on a 

 white ground.
