186 DWIGHT 



Similar to the previous plumage. Above, sepia-brown streaked with clove-brown 

 and tinged with walnut. Below, dull white, clearer on the chin, washed on 

 throat and sides with pinkish buff and streaked broadly on throat and sides 

 with clove-brown, walnut tinged and veiled with whitish or buffy edgings ; the 

 chin flecked ; the breast, abdomen and crissum white. 



4. First Nuptial Plumage acquired by wear which is marked 

 and produces a brown-streaked plumage. The buffs and browns 

 are largely lost. A few new feathers may be assumed about 

 the chin in spring, but there is no evidence of a moult. 



5. Adult Winter Plumage acquired b}- a complete post- 

 nuptial moult beginning in mid-August. Practically indistin- 

 guishable from first winter dress, sometimes paler below, the 

 tertiary' edgings rather darker. 



6. Adult Nuptial Plumage acquired by wear as in the 

 young bird. 



Female. — The sexes are practicalh' alike in all plumages, 

 although the colors will average duller in the female, and the 

 moults are the same. 



Ammodramus princeps (Alayn.). Ipswich Sparrow 



1. Natal Down. No specimen seen. 



2. Juvenal Plumage acquired by a complete postnatal moult. 



Above, buff, palest on the back, streaked narrowly on the pileum, nape and rump, 

 and broadly on the back with deep clove-brown. Below, pale yellowish buff, 

 palest on chin, abdomen and crissum ; narrowly streaked on sides of throat, 

 across jugulum, on sides, flanks and thighs with clove-brown. Wings and tail 

 clove-brown the quills and coverts with whitish or pale cinnamon edgings, be- 

 coming russet on the tertiaries the proximal one white edged. Bill and feet 

 pinkish buff, the former becoming dusky, the latter slightly browner with age. 



This description is based upon nine specimens in my collection 

 taken on Sable Island, Nova Scotia, in July and August. 



3. First Winter Plumage acquired by a partial postju venal 

 moult in August which involves the body plumage, and ap- 

 parently the wing coverts, but not the rest of the win^s nor 

 the tail, young and old becoming practically indistinguishable. 



Similar to the previous plumage. Above, chiefly drab-gray which edges feathers 

 clove-brown centrally bordered by a zone of Vandyke-brown so that the streak- 

 ing above is suffused. The nape and median crown stripe are yellowish. The
